In Case You Missed It: COVID
FDA grants emergency use for Moderna COVID-19 vaccine
As expected, the US Food and Drug Administration granted Moderna an emergency use authorization (EUA) for its messenger RNA COVID-19 vaccine December 18.
There is one final step — the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices will need to recommend its use, as it did 2 days after the Pfizer/BioNTech mRNA vaccine received its EUA on December 10.
The EUA for the Moderna vaccine is “a major milestone in trying to contain this pandemic,” Hana Mohammed El Sahly, MD, told Medscape Medical News.
Scaling up distribution of the two vaccine products will come next. She notes that even under less emergent conditions, making sure people who need a vaccine receive it can be hard. “I hope the media attention around this will make more people aware that there are vaccines that might help them,” said El Sahly, chair of the FDA Vaccines and Related Biological Products Advisory Committee (VRBPAC).
The EUA for the Moderna vaccine follows a review by the independent VRBPAC members on December 17, which voted 20-0 with one abstention to recommend the EUA. The vaccine is authorized for use in people 18 and older.
Emergency approval of a second COVID-19 vaccine “is great — we need all the tools we can to fight this pandemic,” Stephen Schrantz, MD, infectious disease specialist and assistant professor of medicine at the University of Chicago, told Medscape Medical News. “The early data coming from Moderna looks good, and I agree with the FDA that an EUA is indicated.
“It’s incumbent upon all us healthcare professionals to put ourselves out there as supporting this vaccine and supporting people getting it,” Schrantz continued. “We want to make sure people who are on the fence understand this is a safe vaccine that has been vetted appropriately through the FDA and through phase 3 clinical trials.”
“I know the critical role physicians play as vaccine influencers,” AMA President Susan Bailey, MD, said during a December 14 webinar for journalists reporting on COVID-19 vaccines. “We have to continue to do what physicians have always done: review the evidence and trust the science. Lives are at stake.” The webinar was cosponsored by the AMA and the Poynter Institute.
Ramping up healthcare provider immunizations
“I am very excited to see the FDA’s positive review of the Moderna vaccine. We have been waiting to have another vaccine we can use for healthcare workers and staff, and now we have it,” Aneesh Mehta, MD, of Emory University School of Medicine in Atlanta, Georgia, told Medscape Medical News.
“We had been hoping for a vaccine with a 70% or 80% efficacy, and to see two vaccines now with greater than 90% efficacy is remarkable,” he added.
The efficacy levels associated with both mRNA vaccines “did exceed expectations for sure — this is not what we built the studies around. It was surprising in the good sense of the word,” said El Sahly, who is also associate professor of molecular virology and microbiology at Baylor College of Medicine in Houston, Texas.
Unanswered questions remain
Schrantz likewise said the high efficacy rate was important but not all that is needed. “[W]hat we know about this vaccine is it is very effective at preventing disease. We don’t have any understanding at this time whether or not these vaccines prevent infection and transmissibility.”
Bailey said, “The jury is still out on whether or not you can still transmit the virus after you’ve had the vaccine. Hopefully not, but we don’t really know that for sure.”
“It’s risky to think that once you get the shot in your arm everything goes back to normal. It doesn’t,” Bailey added.
Another unknown is the duration of protection following immunization. The Pfizer and Moderna products “have similar constructs, seem to have a reasonable safety profile, and excellent short-term efficacy,” El Sahly said. She cautioned, however, that long-term efficacy still needs to be determined.
Whether any rare adverse events will emerge in the long run is another question. Answers could come over time from the ongoing phase 3 trials, as well as from post-EUA surveillance among vaccine recipients.
“Our work is not done after issuing an EUA,” FDA Commissioner Stephen Hahn, MD, said in a JAMA webinar on December 14. The FDA is closely monitoring for any adverse event rates above the normal background incidence. “We are going to be transparent about it if we are seeing anything that is not at base level.”
“The key is to be humble, keep your eyes open and know that once the vaccine is out there, there may be things we learn that we don’t know now. That is true for virtually any medical innovation,” Paul Offit, MD, director of The Vaccine Education Center at Children’s Hospital of Philadelphia and a member of the FDA VRBPAC, said during the AMA/Poynter Institute webinar.
During the same webinar, an attendee asked about prioritizing immunization for spouses and family members of healthcare workers. “My husband wants to know that too,” replied Patricia A. Stinchfield, APRN, CNP, pediatric nurse practitioner in infectious diseases at Children’s Minnesota, St. Paul.
“It is true we should be thinking about our healthcare workers’ family members. But at this point in time we just don’t have the supplies to address it that way,” said Stinchfield, who is also the president-elect of the National Foundation for Infectious Diseases.
Advantages beyond the numbers?
“The major advantage of having two vaccines is sheer volume,” Mehta said. An additional advantage of more than one product is the potential to offer an option when a specific vaccine is contraindicated. “We could offer someone a different vaccine…similar to what we do with the influenza vaccine.”
“The more the merrier in terms of having more vaccine products,” Schrantz said. Despite differences in shipping, storage, minimum age requirements, and dosing intervals, the Pfizer and Moderna vaccines are very similar, he said. “Really the only difference between these two vaccines is the proprietary lipid nanoparticle — the delivery vehicle if you will.”
Both vaccines “appear very similar in their capacity to protect against disease, to protect [people in] various racial and ethnic backgrounds, and in their capacity to protect against severe disease,” Offit said.
In terms of vaccines in the development pipeline, “We don’t know but we might start to see a difference with the Johnson & Johnson vaccine or the Janssen vaccine, which are single dose. They might confer some advantages, but we are waiting on the safety and efficacy data,” Schrantz said.
As a two-dose vaccine, the AstraZeneca product does not offer an advantage on the dosing strategy, “but it is easier to transport than the mRNA vaccines,” he said. Some concerns with the initial data on the AstraZeneca vaccine will likely need to be addressed before the company applies for an EUA, Schrantz added.
“That is an important question,” El Sahly said. The ongoing studies should provide more data from participants of all ages and ethnic backgrounds that “will allow us to make a determination as to whether there is any difference between these two vaccines.
She added that the Pfizer and Moderna vaccines seem comparable from the early data. “We’ll see if this stands in the long run.”
Future outlook
Now that the FDA approved emergency use of two COVID-19 vaccines, “we need each state to quickly implement their plans to get the vaccines into the hands of providers who need to give the vaccines,” Mehta said. “We are seeing very effective rollout in multiple regions of the country. And we hope to see that continue as we get more vaccines from manufacturers over the coming months.”
“Within a year of identifying the sequence of this virus we have two large clinical vaccine trials that show efficacy,” Offit said. “That was an amazing technologic accomplishment, but now comes the hard part. Mass producing this vaccine, getting it out there, making sure everybody who most benefits gets it, is going to be really, really hard.”
“But I’m optimistic,” Offit said. “If we can do this by next Thanksgiving, we’re going to see a dramatic drop in the number of cases, hospitalizations and deaths, and we can get our lives back together again.”
“My greatest hope is that a year from now we look back and realize we did something really amazing together,” Bailey said, “and we have a feeling of accomplishment and appreciation for all the hard work that has been done.”
Mehta shared the important message he shares when walking around the hospital: “While these vaccines are coming and they are very promising, we need to continue to remember the 3 Ws: wearing a mask, washing your hands, and watching your distance,” he said.
“With the combination of those 3Ws and those vaccines, we will hopefully come through this COVID pandemic.”
El Sahly receives funding through the NIH for her research, including her role as co-chair of the Moderna vaccine phase 3 clinical trial. Schrantz is a site investigator for the Moderna and Janssen vaccine trials. Mehta also receives funding through the NIH. None of these experts had any relevant financial disclosures.

COVID-19 vaccine found effective but doctors watching for reactions, adverse events
The Pfizer COVID-19 vaccine was shown to be highly effective in a large trial, but clinicians will be waiting and watching for reactions and adverse events in their vaccinated patients.
A two-dose regimen of the BNT162b2 mRNA COVID-19 vaccine was found to be safe and 95% effective in preventing SARS-CoV-2 infection in persons aged 16 years and older, according to an ongoing phase 2/3 trial. Pfizer and BioNTech published safety and efficacy results from the landmark global phase 1/2/3 trial of their COVID-19 vaccine candidate in the New England Journal of Medicine .
“We previously reported phase 1 safety and immunogenicity results from clinical trials of the vaccine candidate BNT162b2,” lead author Fernando P. Polack, MD, of Vanderbilt University, Nashville, Tenn., and colleagues wrote. “This data set and [present] trial results are the basis for an application for emergency-use authorization,” they explained.
The BNT162b2 vaccine trial
Among 43,448 individuals aged 16 years and older, the efficacy, safety, and immunogenicity of the BNT162b2 vaccine candidate was evaluated in a continuous phase 1/2/3 study. Participants were randomly assigned (1:1) to receive two injections of either 30 mcg of BNT162b2 (n = 21,720) or saline placebo (n = 21,728) administered intramuscularly 21 days apart. The safety evaluation, where subjects were monitored 30 minutes post vaccination for acute reactions, was observer blinded.
Eligibility criteria included healthy individuals or those with stable chronic medical conditions, including viral hepatitis B and C, as well as human immunodeficiency virus. Persons with a diagnosis of an immunocompromising condition, those receiving immunosuppressive therapy, and individuals with a medical history of COVID-19 were excluded.
The first primary endpoint was efficacy of BNT162b2 against laboratory-confirmed COVID-19 with onset at least 7 days following the second dose. The primary safety endpoint was local and systemic reactions occurring within 7 days post injection of BNT162b2 or placebo.
Safety
“At the data cutoff date of Oct. 9, a total of 37,706 participants had a median of at least 2 months of safety data available after the second dose and contributed to the main safety data set,” the authors wrote.
Among these participants, 83% were White, 28% were Hispanic or Latinx, and 9% were Black or African American; 49% of subjects were female and the median age was 52 years, with 42% over aged 55 years.
Overall, BNT162b2 had a favorable safety profile. Mild to moderate pain at the injection site within 7 days after the injection was the most frequently reported local reaction (<1% across all age groups reported severe pain). Most local reactions resolved within 1-2 days and no grade 4 reactions were reported.
The investigators reported: “Fever (temperature, ≥38° C) was reported after the second dose by 16% of younger vaccine recipients and by 11% of older recipients. Only 0.2% of vaccine recipients and 0.1% of placebo recipients reported fever (temperature, 38.9-40° C) after the first dose, as compared with 0.8% and 0.1%, respectively, after the second dose.”
BNT162b2 recipients had more injection-site pain than those receiving the placebo. After the first and second doses, younger recipients (under 55 years) had more pain at the injection site (83 vs. 14 and 78 vs. 12 events, respectively), redness (5 vs. 1 and 6 vs. 1), and swelling (6 vs. 0 and 6 vs. 0), compared with placebo recipients.
The same trend was observed for patients aged over 55 years, with vaccine recipients reporting more pain at the injection site (71 vs. 9 and 66 vs. 8 events, respectively), redness (5 vs. 1 and 7 vs. 1), and swelling (7 vs. 1 and 7 vs. 1) than placebo recipients.
Pain was less common overall among vaccine recipients aged over 55 years (71% reported pain after the first dose; 66% post second dose) than among younger vaccine recipients (83% post first dose; 78% post second dose).
The most common systemic events following the second dose were fatigue and headache, which occurred in 59% and 52% of younger vaccine recipients and 51% and 39% of older vaccine recipients, respectively. But fatigue and headache were also reported by participants in the placebo group (23% and 24%, respectively, post second dose, among younger vaccine recipients; 17% and 14% among older recipients).
The incidence of serious adverse events was low and similar in the vaccine (0.6%) and placebo (0.5%) arms. Severe systemic events occurred in 2% or less of vaccine recipients following either dose, except for fatigue (3.8%) and headache (2.0%) post second dose. No deaths were considered to be vaccine or placebo related.
“The safety appears comparable to other vaccines, but the relatively short period of observation, 2 months, and the relatively small number of subjects who have received the vaccine (less than 30,000), compared to the hundreds of millions likely to ultimately receive the vaccine, precludes conclusions regarding the potential for rare long term adverse effects,” David L. Bowton, MD, FCCP, a pulmonologist and professor emeritus of critical care anesthesiology at Wake Forest University, Winston-Salem, N.C., said in an interview. “Clinicians should be aware of the risk of anaphylactic reactions and discuss it with their patients [who have] a history of these reactions.”
Efficacy
Among 36,523 subjects without evidence of existing or prior COVID-19 infection, 8 cases of COVID-19 with onset at least 7 days after the second dose were seen among vaccine recipients and 162 among placebo recipients, corresponding to 95.0% vaccine efficacy (95% credible interval, 90.3%-97.6%).
“Supplemental analyses indicated that vaccine efficacy among subgroups defined by age, sex, race, ethnicity, obesity, and presence of a coexisting condition was generally consistent with that observed in the overall population,” the authors wrote.
Between the first and second doses, 39 cases of COVID-19 were observed among BNT162b2 recipients and 82 cases among placebo recipients, corresponding to 52% vaccine efficacy during the 21-day interval (95% CI, 29.5%-68.4%) suggesting early protection may begin as soon as 12 days after the first injection.
“This is an incredible achievement given that an effective vaccine has never been developed and approved for use in such a short timeframe,” Dr. Bowton explained. “That the vaccine is highly effective in reducing the incidence of symptomatic COVID-19 seems incontrovertible.”
“This vaccine has shockingly amazing efficacy and is well tolerated, and the results are beyond even optimistic projections,” Douglas S. Paauw, MD, of the University of Washington, Seattle, said in an interview.
Questions remain
“It is not yet known if the vaccine prevents asymptomatic infections, with their attendant risk of contagion, as rates of seroconversion of trial participants against betacoronavirus nucleoproteins not included in the vaccine has not been reported,” Dr. Bowton commented.
“Common questions our patients will ask us remain unanswered for now, [including] how long will the protection last, is it safe in pregnant women, and does it prevent asymptomatic infection,” Dr. Paauw explained. “We do not know everything about longer term side effects, but the benefits of this vaccine appear to outweigh the risks of the vaccine.”
The researchers noted these and other limitations in their report, acknowledging that longer follow-up is needed to evaluate long-term safety of the vaccine.
This study was supported by BioNTech and Pfizer. Several authors disclosed financial relationships with Pfizer and other pharmaceutical companies outside the submitted work. Dr. Bowton and Dr. Paauw had no conflicts to disclose.

Participants were randomly assigned (1:1) to receive two injections of either 30 mcg of BNT162b2 (n = 21,720) or saline placebo (n = 21,728) administered intramuscularly 21 days apart. The safety evaluation, where subjects were monitored 30 minutes post vaccination for acute reactions, was observer blinded.
Eligibility criteria included healthy individuals or those with stable chronic medical conditions, including viral hepatitis B and C, as well as human immunodeficiency virus. Persons with a diagnosis of an immunocompromising condition, those receiving immunosuppressive therapy, and individuals with a medical history of COVID-19 were excluded.
The first primary endpoint was efficacy of BNT162b2 against laboratory-confirmed COVID-19 with onset at least 7 days following the second dose. The primary safety endpoint was local and systemic reactions occurring within 7 days post injection of BNT162b2 or placebo.
Safety
“At the data cutoff date of Oct. 9, a total of 37,706 participants had a median of at least 2 months of safety data available after the second dose and contributed to the main safety data set,” the authors wrote.
Among these participants, 83% were White, 28% were Hispanic or Latinx, and 9% were Black or African American; 49% of subjects were female and the median age was 52 years, with 42% over aged 55 years.
Overall, BNT162b2 had a favorable safety profile. Mild to moderate pain at the injection site within 7 days after the injection was the most frequently reported local reaction (<1% across all age groups reported severe pain). Most local reactions resolved within 1-2 days and no grade 4 reactions were reported.
The investigators reported: “Fever (temperature, ≥38° C) was reported after the second dose by 16% of younger vaccine recipients and by 11% of older recipients. Only 0.2% of vaccine recipients and 0.1% of placebo recipients reported fever (temperature, 38.9-40° C) after the first dose, as compared with 0.8% and 0.1%, respectively, after the second dose.”
BNT162b2 recipients had more injection-site pain than those receiving the placebo. After the first and second doses, younger recipients (under 55 years) had more pain at the injection site (83 vs. 14 and 78 vs. 12 events, respectively), redness (5 vs. 1 and 6 vs. 1), and swelling (6 vs. 0 and 6 vs. 0), compared with placebo recipients.
The same trend was observed for patients aged over 55 years, with vaccine recipients reporting more pain at the injection site (71 vs. 9 and 66 vs. 8 events, respectively), redness (5 vs. 1 and 7 vs. 1), and swelling (7 vs. 1 and 7 vs. 1) than placebo recipients.
Pain was less common overall among vaccine recipients aged over 55 years (71% reported pain after the first dose; 66% post second dose) than among younger vaccine recipients (83% post first dose; 78% post second dose).
The most common systemic events following the second dose were fatigue and headache, which occurred in 59% and 52% of younger vaccine recipients and 51% and 39% of older vaccine recipients, respectively. But fatigue and headache were also reported by participants in the placebo group (23% and 24%, respectively, post second dose, among younger vaccine recipients; 17% and 14% among older recipients).
The incidence of serious adverse events was low and similar in the vaccine (0.6%) and placebo (0.5%) arms. Severe systemic events occurred in 2% or less of vaccine recipients following either dose, except for fatigue (3.8%) and headache (2.0%) post second dose. No deaths were considered to be vaccine or placebo related.
“The safety appears comparable to other vaccines, but the relatively short period of observation, 2 months, and the relatively small number of subjects who have received the vaccine (less than 30,000), compared to the hundreds of millions likely to ultimately receive the vaccine, precludes conclusions regarding the potential for rare long term adverse effects,” David L. Bowton, MD, FCCP, a pulmonologist and professor emeritus of critical care anesthesiology at Wake Forest University, Winston-Salem, N.C., said in an interview. “Clinicians should be aware of the risk of anaphylactic reactions and discuss it with their patients [who have] a history of these reactions.”
Efficacy
Among 36,523 subjects without evidence of existing or prior COVID-19 infection, 8 cases of COVID-19 with onset at least 7 days after the second dose were seen among vaccine recipients and 162 among placebo recipients, corresponding to 95.0% vaccine efficacy (95% credible interval, 90.3%-97.6%).
“Supplemental analyses indicated that vaccine efficacy among subgroups defined by age, sex, race, ethnicity, obesity, and presence of a coexisting condition was generally consistent with that observed in the overall population,” the authors wrote.
Between the first and second doses, 39 cases of COVID-19 were observed among BNT162b2 recipients and 82 cases among placebo recipients, corresponding to 52% vaccine efficacy during the 21-day interval (95% CI, 29.5%-68.4%) suggesting early protection may begin as soon as 12 days after the first injection.
“This is an incredible achievement given that an effective vaccine has never been developed and approved for use in such a short timeframe,” Dr. Bowton explained. “That the vaccine is highly effective in reducing the incidence of symptomatic COVID-19 seems incontrovertible.”
“This vaccine has shockingly amazing efficacy and is well tolerated, and the results are beyond even optimistic projections,” Douglas S. Paauw, MD, of the University of Washington, Seattle, said in an interview.
Questions remain
“It is not yet known if the vaccine prevents asymptomatic infections, with their attendant risk of contagion, as rates of seroconversion of trial participants against betacoronavirus nucleoproteins not included in the vaccine has not been reported,” Dr. Bowton commented.
“Common questions our patients will ask us remain unanswered for now, [including] how long will the protection last, is it safe in pregnant women, and does it prevent asymptomatic infection,” Dr. Paauw explained. “We do not know everything about longer term side effects, but the benefits of this vaccine appear to outweigh the risks of the vaccine.”
The researchers noted these and other limitations in their report, acknowledging that longer follow-up is needed to evaluate long-term safety of the vaccine.
This study was supported by BioNTech and Pfizer. Several authors disclosed financial relationships with Pfizer and other pharmaceutical companies outside the submitted work. Dr. Bowton and Dr. Paauw had no conflicts to disclose.

The Pfizer COVID-19 vaccine was shown to be highly effective in a large trial, but clinicians will be waiting and watching for reactions and adverse events in their vaccinated patients.
A two-dose regimen of the BNT162b2 mRNA COVID-19 vaccine was found to be safe and 95% effective in preventing SARS-CoV-2 infection in persons aged 16 years and older, according to an ongoing phase 2/3 trial. Pfizer and BioNTech published safety and efficacy results from the landmark global phase 1/2/3 trial of their COVID-19 vaccine candidate in the New England Journal of Medicine .
“We previously reported phase 1 safety and immunogenicity results from clinical trials of the vaccine candidate BNT162b2,” lead author Fernando P. Polack, MD, of Vanderbilt University, Nashville, Tenn., and colleagues wrote. “This data set and [present] trial results are the basis for an application for emergency-use authorization,” they explained.

Contact tracing in hospitals falls off as COVID-19 cases rise
Like most health care workers at his hospital in Lafayette, Ind., Ramesh Adhikari, MD, FHM, occasionally gets an email noting that a patient he saw later tested positive for COVID-19. He’s reminded to self-monitor for symptoms. But 10 months into the pandemic, it has become increasingly unlikely for contact tracing investigations to result in clinicians quarantining.
The very act of working in the hospital, Dr. Adhikari said, means being likely to see COVID-19 every day, whether in a known patient or an asymptomatic person who tests positive later. If hospitalists had to quarantine after every interaction with a COVID-positive person, there wouldn’t be anyone left to do their jobs.
“It’s really hard to do [contact tracing] in health care workers thoroughly because of the way we work,” Dr. Adhikari said. “It’s impossible to do it absolutely.”
In a recently updated guidance, the Centers for Disease Control and Prevention extended more leeway in contact tracing when community rates of COVID-19 surge, even allowing that contact tracing “may not be possible” in certain situations. And by defining an exposure more narrowly – health care workers are only considered “exposed” if their contact was more than 15 minutes or lacking in some form of PPE – the guidelines suggest that hospitals can rely more on universal PPE and screening protocols, as Dr. Adhikari’s hospital does, and less on extensive contact tracing to curtail viral spread.
Accordingly, while contact tracing has gotten more lax, doctors say, universal precautions – including full PPE and screening of symptoms for patients and health care workers – have become more stringent.
It’s a shift from the beginning of the pandemic. At first, CDC recommended wearing masks only during aerosol-producing procedures. Exposures were frequently reported and health care workers sent home. With more evidence in favor of stricter PPE requirements, hospitals including the one where Shyam Odeti, MD, FHM, works in Johnson City, Tenn., have adopted a universal precaution strategy – requiring masks everywhere and a gown, face shield, gloves, and N95 to enter a COVID-positive patient’s room. Thus, most exposures fall into that low-risk category.
“If I get it and am asymptomatic, I don’t think my colleagues would be exposed by any means because of these stringent policies being enforced,” said Dr. Odeti, a hospitalist who often wears a surgical mask on top of his N95 all day. “And U.S. health care is not in a state that can afford to quarantine health care workers for 14 days.”
Can universal PPE precautions supplant contact tracing?
The extent of contact tracing varies by hospital. Larger university and community hospitals often have infection control and occupational health teams that can do their own contact tracing, while smaller institutions can’t always spare staff. And some state health departments get involved with contact tracing of health care workers while others do not.
“I would venture to say that most hospitals are doing something in terms of contact tracing,” said Pam Falk, MPH, CIC, a member of the Association for Professionals in Infection Control and Epidemiology’s COVID-19 task force and an infection control consultant. “It kind of depends on their bandwidth.”
But there’s no longer a norm. Outside of a pandemic, with ample staffing and far fewer instances that need to be investigated, standards for contact tracing are higher, Dr. Falk said: When a patient is found to have an airborne disease such as tuberculosis, measles, mumps, or chickenpox, a hospital’s infection prevention team should investigate, confirm the diagnosis and identify everyone who was exposed. The hospital’s occupational health team assists in deciding who will likely need prophylactic treatment and if employees should be furloughed. The thoroughness of such measures has always depended on a hospital’s bandwidth.
Because PPE seems to be able to contain COVID-19 better than some of the older diseases targeted by contact tracing, universal protections may be a reasonable alternative in current circumstances, doctors said – if PPE is available.
“At the end of the day, universal source control with surgical masks – and ideally eye protection for clinicians as well – should prevent most transmissions,” said Aaron Richterman, MD, from the division of infectious diseases at the Hospital of the University of Pennsylvania, Philadelphia, who coauthored a JAMA commentary on decreased transmission rates in hospitals.
Contact tracing is still useful, though, to identify weaknesses in universal protection measures, he said.
“I don’t think it’s worth abandoning. It’s like a tool in the toolbox. All are imperfect, and none work 100% of the time,” Dr. Richterman said, but using all of them can achieve a fairly high measure of safety. Of the tools, universal masking likely works the best, he contends, so it should be the top pick for hospitals without resources to use all of the tools.
A recent incident at Brigham and Women’s Hospital in Boston is a case study in how contact tracing can work together with universal protections to identify cracks in the system, said Dr. Richterman, who worked at the hospital earlier in the pandemic.
Mass General Brigham adopted a universal masking policy for staff and patients in March 2020. Then, when the system experienced an outbreak in September, the hospital did “a very detailed public evaluation that included contact tracing and universal testing,” Dr. Richterman said. Testing even included genetic analysis of the virus to confirm which cases were hospital acquired. In the end, the hospital identified weaknesses in infection control that could be rectified, such as clinicians eating too close together.
“The approach is not to point fingers, but to say: ‘What’s wrong with the system and how do we improve?’ ” Dr. Richterman said. “To ask, why did that maskless transmission happen? Is there not enough space to eat? Are people working too many hours? It’s useful for systems to understand where transmissions are happening.”
Amith Skandhan, MD, SFHM, a hospitalist in Dothan, Ala., is comfortable without much contact tracing as long as there is universal PPE use. His hospital informs clinicians of exposures, but “basically we’re trained to treat every patient as if they had COVID,” he said, so “I feel more secure in the hospital than in the community.” Masks have become so habitual they’re like part of your regular clothing, he said – you feel incomplete if you don’t have one.
While ad hoc approaches to contact tracing may be useful in the current stage of the pandemic, they are likely to be short-lived: Once a community’s positivity rate falls, the CDC’s guidance suggests how hospitals can return to full contact tracing.

Should I be afraid of getting COVID again?
Is it over or do I have to brace myself for the possibility of a reinfection? Moreover, could the second time potentially be worse than the first?
I was diagnosed with COVID in March of this year. After spending 10 days in the hospital, and one night in the ICU, it took another 2 months for the air-hunger, headaches, and fatigue to completely resolve. Compared with many other unfortunate victims, I did all right – and I am very grateful for the care I received.
Now, as the surge in cases takes new life, I will be on the front lines taking care of patients. Having had an eventful personal encounter with the virus, I now have a unique vantage point and remain fully committed to paying my fortunate circumstances forward. Although I can’t help but have the same question faced by millions of others: Am I safe now?
It is no surprise that studies have shown health care workers comprising 6% of COVID hospital admissions, with one-third of these admissions being nurses. Recently, we heard that over 900 health care workers at Mayo Clinic had acquired the infection in the first 2 weeks of the ongoing second COVID surge. Are these frontline workers protected? Can they return to work with no fear of a rerun? Or, for that matter, anyone who has been afflicted by COVID – are they now forever immune?
There are no clear answers here. But to understand this a little, let’s quickly revisit some basic principles of immunity.
Innate and adaptive immunity
Simply put, there are two forms of immunity: innate and adaptive. Innate immunity encompasses our body’s natural protective mechanisms that come into play almost immediately. This enables recognition of the virus and activates an immediate antiviral defense and attempt at removal of the infective agent. This, however, does not always do the job. Accordingly, a couple weeks after the initial exposure to the pathogen, adaptive immunity is invoked. Circulating white blood cells within our body recognize the virus and set off an immune response, involving the activation of T and B cells that actively attack the infective agent. It is this T- and B-cell–mediated immunity that should protect one against a second infection with the same agent.
What about herd immunity?
Herd immunity is defined as essentially yielding to the virus and letting it spread naturally in order to develop community-wide immunity. By consequence of a large proportion of the population becoming immune after exposure to the disease, person-to-person spread can potentially be mitigated. This does not confer immunity to the virus at the individual level; rather, it reduces the risk of vulnerable people coming in contact with the pathogen.
Unfortunately, depending on herd immunity as a way to deal with COVID-19 has not worked well, even in well-contained countries like Sweden, where a disproportionate number of their most vulnerable populations have died. It is self-evident that containment strategies with vaccination may be our best way forward to achieve herd immunity. Not surrendering to the virus.
Am I safe from reinfection?
In all honesty, we’re not entirely sure. But it is important to recognize a few points when considering your relative safety.
- The immune system is far from perfect. Not everyone has a robust immune response. And in those who do, the immune response can wane over time, potentially allowing for reinfection. While rare, there have already been some clearly documented reinfections, four that have been confirmed and published; two patients (in Nevada and Ecuador) actually fared worse the second time around.
- The virus can mutate and escape detection by the immune system. One could still be susceptible to reinfection from a different strain. (At least, this remains the case with the influenza virus.) There is some evidence that SARS-CoV-2 does not mutate rapidly, and hence this may not be a problem. But we don’t know for certain, at least as of yet.
- Even a vigorous immune response can be overwhelmed by the virus. It is unclear whether the relative length of time and the amount of virus exposure could undermine a previously primed immune system.
A prior infection and a consequent healthy immunity may help you combat a reinfection but it does not prevent you from harboring or carrying the virus. You may be asymptomatic, but you can still be a carrier and spread the infection. I am a strong advocate for limiting your exposure to others no matter your previous exposure status, in order to limit the spread of the virus.
So, what should I do?
I guess the answer is that you can’t be too careful. Not everyone has had their antibody levels tested, and even if positive, it is unclear how well that affords protection. It is best to presume that you are vulnerable for a reinfection and that you can still carry and spread the virus. This may be the safest approach until we actually achieve herd immunity through vaccination.
Even then, for a period of time, there will remain a sense of uncertainty. So, containment strategies inclusive of distancing and masking will and should remain a way of life at least until mid-2021, when we will be in a better position to reassess the landscape.
The surge is back. As I repay my debt and get back to the front line, I will continue to mask up and practice distancing. I am taking no chances of getting reinfected or being an asymptomatic carrier.
I had COVID, I also have antibodies, and I will be taking the vaccine. I implore you all to do the same.

Moderna COVID-19 vaccine wins decisive recommendation from FDA panel
The US Food and Drug Administration (FDA) put Moderna’s application before its Vaccines and Related Biological Products Advisory Committee. The panel voted 20-0 on this question: “Based on the totality of scientific evidence available, do the benefits of the Moderna COVID-19 Vaccine outweigh its risks for use in individuals 18 years of age and older?” There was one abstention.
The FDA is not bound to act on the recommendations of its advisers, but the agency usually takes the panel’s advice. The FDA cleared the similar Pfizer-BioNTech vaccine on December 11 through an emergency use authorization (EUA), following a positive vote for the product at a December 10 advisory committee meeting. In this case, the FDA staff appeared to be pushing for a broad endorsement of the Moderna vaccine, for which the agency appears likely to soon also grant an EUA.
Marion Gruber, PhD, director of the Office of Vaccines Research and Review at FDA’s Center for Biologics Evaluation and Research, earlier rebuffed attempts by some of the panelists to alter the voting question. Some panelists wanted to make tweaks, including a rephrasing to underscore the limited nature of an EUA, compared with a more complete approval through the biologics license application (BLA) process.
FDA panelist Michael Kurilla, MD, PhD, of the National Institutes of Health was the only panelist to abstain from voting. He said he was uncomfortable with the phrasing of the question.
“In the midst of a pandemic and with limited vaccine supply available, a blanket statement for individuals 18 years and older is just too broad,” he said. “I’m not convinced that for all of those age groups the benefits do actually outweigh the risks.”
In general, though, there was strong support for Moderna’s vaccine. FDA panelist James Hildreth Sr, MD, PhD, of Meharry Medical College in Nashville, Tennessee spoke of the “remarkable achievement” seen in having two vaccines ready for clearance by December for a virus that only emerged as a threat this year.
Study data indicate the primary efficacy endpoint demonstrated vaccine efficacy (VE) of 94.1% (95% CI, 89.3% - 96.8%) for the Moderna vaccine, with 11 COVID-19 cases in the vaccine group and 185 COVID-19 cases in the placebo group, the FDA staff noted during the meeting.
The advisers and FDA staff also honed in on several key issues with COVID-19 vaccines, including the challenge of having people in the placebo groups of studies seek to get cleared vaccines. Also of concern to the panel were early reports of allergic reactions seen with the Pfizer product.
Doran L. Fink, MD, PhD, an FDA official who has been closely involved with the COVID-19 vaccines, told the panel that two healthcare workers in Alaska had allergic reactions minutes after receiving the Pfizer vaccine, one of which was a case of anaphylactic reaction that resulted in hospitalization.
In the United Kingdom, there were two cases reported of notable allergic reactions, leading regulators there to issue a warning that people who have a history of significant allergic reactions should not currently receive the Pfizer-BioNTech vaccine.
The people involved in these incidents have recovered or are recovering, Fink said. But the FDA expects there will be additional reports of allergic reactions to COVID-19 vaccines.
“These cases underscores the need to remain vigilant during the early phase of the vaccination campaign,” Fink said. “To this end, FDA is working with Pfizer to further revise factsheets and prescribing information for their vaccine to draw attention to CDC guidelines for post- vaccination monitoring and management of immediate allergic reactions.”
mRNA vaccines in the lead
An FDA emergency clearance for Moderna’s product would be another vote of confidence in a new approach to making vaccines. Both the Pfizer-BioNTech and Moderna vaccines provide the immune system with a kind of blueprint in the form of genetic material, mRNA. The mRNA sets the stage for the synthesis of the signature spike protein that the SARS-CoV-2 virus uses to attach to and infect human cells.
In a December 15 commentary for this news organization Michael E. Pichichero, MD, wrote that the “revolutionary aspect of mRNA vaccines is the speed at which they can be designed and produced.”
“This is why they lead the pack among the SARS-CoV-2 vaccine candidates and why the National Institute of Allergy and Infectious Diseases provided financial, technical, and/or clinical support. Indeed, once the amino acid sequence of a protein can be determined (a relatively easy task these days) it’s straightforward to synthesize mRNA in the lab — and it can be done incredibly fast,” he wrote.
The FDA allowed one waiver for panelist James K. Hildreth in connection with his personal relationship to a trial participant and his university’s participation in vaccine testing.

Vaccine rollout on track, expect 300 million doses through March: Feds
If the initial success of the Pfizer-BioNTech rollout continues, and emergency use authorization (EAU) is granted to Moderna and Johnson & Johnson vaccines in development, Operation Warp Speed officials expect to have 300 million doses of COVID-19 vaccines to distribute across the United States between now and March 31.
The initial rollout remains on track, said Alex Azar, US Department of Health and Human Services (HHS) secretary, during a media briefing today. “We continue to have good news to report. As of today, shipments of vaccine will have been delivered to every delivery site identified by public health jurisdictions for our first wave of shipments.”
Anomalies in shipments to California and Alabama arose when temperature monitors showed the Pfizer vaccine dropped lower than the recommended -80 ºC (-112 °F). These vaccine trays remained on delivery trucks and were returned to Pfizer for prompt replacement, said Operation Warp Speed Chief Operating Officer Gen. Gustave F. Perna.
Azar estimated another 2 million doses of the Pfizer vaccine will be available next week. “And if the Moderna vaccine is authorized by the FDA in the coming days, we have allocated nearly 5.9 million doses of that product.”
The Moderna vaccine data released this week look promising, said Moncef Slaoui, PhD, Operation Warp Speed chief scientific adviser. “In the short term, I expect the protection to be quite significant.”
The findings in the first 2 weeks after the first dose show up to 65% protection, he said, and predicted the second-dose efficacy data will be coming in the next few weeks.
Enrollment in the phase 3 Johnson & Johnson trial with nearly 44,000 participants is expected to end December 17. Initial efficacy results are anticipated by early January, with more complete efficacy numbers by late January, Slaoui said.
The AstraZeneca COVID-19 vaccine trial also is underway with enrollment continuing. “We expect accruement to end in late December or early next year, with first results expected probably in February,” Slaoui said.
Antibody treatments underutilized
The media briefing also addressed COVID-19 therapeutics. Azar reported low uptake of available antibody therapies. “I want to remind Americans that there are two authorized antibody treatments that Operation Warp Speed has supported. They can help prevent hospitalization in those patients with the highest risk for severe disease.”
The higher-risk group includes those who are 65 and older and people with comorbid conditions that put them at increased risk for COVID-19 hospitalization.
The federal government allocated more than 330,000 doses of these treatments and many states have product available, Azar said.
Slaoui agreed, saying there is a “disappointing level of usage of monoclonal antibody therapy in hospitals. We look forward to that improving.”
Up to 3 billion vaccine doses possible
“We now have more than 900 million doses of the vaccine we have contracted delivery for,” Azar said. The government has options to increase that to a total of 3 billion doses.
In addition to the 100 million Pfizer vaccine doses and 100 million Moderna doses already ordered, the government just took an option for another 100 million Moderna doses for the second quarter of 2021. Operation Warp Speed officials are negotiating with Pfizer for additional product as well.
Azar added that there are 100 million doses of the Johnson & Johnson vaccine in active production and expects AstraZeneca can provide 300 million doses of their product.
With the possibility of three or more vaccine products and with 330 million Americans, minus the 70 million or so children under age 16, “we believe we will actually have surplus supplies,” Azar said. Plans are to take the US surplus vaccine and surplus manufacturing capacity “and use that for the benefit of the world community.”

Antibody treatments underutilized
The media briefing also addressed COVID-19 therapeutics. Azar reported low uptake of available antibody therapies. “I want to remind Americans that there are two authorized antibody treatments that Operation Warp Speed has supported. They can help prevent hospitalization in those patients with the highest risk for severe disease.”
The higher-risk group includes those who are 65 and older and people with comorbid conditions that put them at increased risk for COVID-19 hospitalization.
The federal government allocated more than 330,000 doses of these treatments and many states have product available, Azar said.
Slaoui agreed, saying there is a “disappointing level of usage of monoclonal antibody therapy in hospitals. We look forward to that improving.”
Up to 3 billion vaccine doses possible
“We now have more than 900 million doses of the vaccine we have contracted delivery for,” Azar said. The government has options to increase that to a total of 3 billion doses.
In addition to the 100 million Pfizer vaccine doses and 100 million Moderna doses already ordered, the government just took an option for another 100 million Moderna doses for the second quarter of 2021. Operation Warp Speed officials are negotiating with Pfizer for additional product as well.
Azar added that there are 100 million doses of the Johnson & Johnson vaccine in active production and expects AstraZeneca can provide 300 million doses of their product.
With the possibility of three or more vaccine products and with 330 million Americans, minus the 70 million or so children under age 16, “we believe we will actually have surplus supplies,” Azar said. Plans are to take the US surplus vaccine and surplus manufacturing capacity “and use that for the benefit of the world community.”

If the initial success of the Pfizer-BioNTech rollout continues, and emergency use authorization (EAU) is granted to Moderna and Johnson & Johnson vaccines in development, Operation Warp Speed officials expect to have 300 million doses of COVID-19 vaccines to distribute across the United States between now and March 31.
The initial rollout remains on track, said Alex Azar, US Department of Health and Human Services (HHS) secretary, during a media briefing today. “We continue to have good news to report. As of today, shipments of vaccine will have been delivered to every delivery site identified by public health jurisdictions for our first wave of shipments.”
Anomalies in shipments to California and Alabama arose when temperature monitors showed the Pfizer vaccine dropped lower than the recommended -80 ºC (-112 °F). These vaccine trays remained on delivery trucks and were returned to Pfizer for prompt replacement, said Operation Warp Speed Chief Operating Officer Gen. Gustave F. Perna.
Azar estimated another 2 million doses of the Pfizer vaccine will be available next week. “And if the Moderna vaccine is authorized by the FDA in the coming days, we have allocated nearly 5.9 million doses of that product.”
The Moderna vaccine data released this week look promising, said Moncef Slaoui, PhD, Operation Warp Speed chief scientific adviser. “In the short term, I expect the protection to be quite significant.”
The findings in the first 2 weeks after the first dose show up to 65% protection, he said, and predicted the second-dose efficacy data will be coming in the next few weeks.
Enrollment in the phase 3 Johnson & Johnson trial with nearly 44,000 participants is expected to end December 17. Initial efficacy results are anticipated by early January, with more complete efficacy numbers by late January, Slaoui said.

COVID-19 ranks as a leading cause of death in United States
Adults over age 45 were more likely to die from COVID-19 than car crashes, respiratory diseases, drug overdoses, and suicide. And those over age 55 faced even higher rates of dying because of the coronavirus.
“The current exponential increase in COVID-19 is reaching a calamitous scale in the U.S.,” the authors wrote. “Putting these numbers in perspective may be difficult.”
Population health researchers at Virginia Commonwealth University put COVID-19 deaths into context by comparing this year’s numbers to the leading causes of death for March through October 2018, sorting by age.
By October 2020, COVID-19 had become the third leading cause of death overall for those between the ages of 45 and 84 years, following after heart disease and cancer. For those over age 85, COVID-19 was the second leading cause of death, surpassing cancer and following behind heart disease.
For people aged 35-44 years, COVID-19 surpassed car crashes and respiratory diseases and was slightly lower than suicide, heart disease, and cancer. For those under age 35, drug overdoses, suicide, and car crashes remained the leading causes of death.
Importantly, the authors wrote, death rates for the two leading causes – heart disease and cancer – are about 1,700 and 1,600 per day, respectively. COVID-19 deaths have surpassed these numbers individually throughout December and, on Wednesday, beat them combined. More than 3,400 deaths were reported, according to the COVID Tracking Project, marking an all-time high that continues to increase. Hospitalizations were also at a new high, with more than 113,000 COVID-19 patients in hospitals across the country, and another 232,000 new cases were reported.
“With COVID-19 mortality rates now exceeding these thresholds, this infectious disease has become deadlier than heart disease and cancer,” the authors wrote. “Its lethality may increase further as transmission increases with holiday travel and gatherings and with the intensified indoor exposure that winter brings.”
The reported number of COVID-19 deaths is likely a 20% underestimate, they wrote, attributable to delays in reporting and an increase in non–COVID-19 deaths that were undetected and untreated because of pandemic-related disruptions. Since the coronavirus is communicable and spreads easily, COVID-19 deaths are particularly unique and worrying, they said.
“Individuals who die from homicide or cancer do not transmit the risk of morbidity and mortality to those nearby,” they wrote. “Every COVID-19 death signals the possibility of more deaths among close contacts.”
The fall surge in cases and deaths is widespread nationally, as compared to the spring, with hot spots on both coasts and in rural areas, according to an accompanying editorial in JAMA from public health researchers at the Harvard T.H. Chan School of Public Health, Boston. People of color have faced twice the death rate as well, with one in 875 Black people and one in 925 Indigenous people dying from COVID-19, as compared with one in 1,625 White people.
“The year 2020 ends with COVID-19 massively surging, as it was in the spring, to be the leading cause of death,” they wrote. “The accelerating numbers of deaths fall far short of fully capturing each devastating human story: Every death represents untold loss for countless families.”
Vaccines offer hope, they said, but won’t prevent the upcoming increase in COVID-19 hospitalizations and deaths this winter. In 2021, containing the pandemic will require national coordination, resources to help overwhelmed health care workers, new support for state and local public health officials, a stimulus package for schools and businesses, and financial aid for people on the brink of eviction. The country needs federal coordination of testing, contact tracing, personal protective equipment, travel precautions, and a face mask mandate, they wrote.
“Ending this crisis will require not only further advances in treatment but also unprecedented commitment to all aspects of prevention, vaccination, and public health,” they wrote. “Only by doing so can future years see this illness revert back to the unfamiliar and unknown condition it once was.”

Pediatricians want kids to be part of COVID vaccine trials
If clinical trials for COVID-19 vaccines aren’t expanded soon to include children, it’s unlikely that even kids in their teens will be vaccinated in time for the next school year.
The hurdle is that COVID vaccine makers are only in the early stages of testing their products on children. The Pfizer vaccine authorized for use by the Food and Drug Administration on Friday was greenlighted only for people aged 16 years and older. Moderna just started trials for 12- to 17-year-olds for its vaccine, likely to be authorized later this month.
It will take months to approve use of the vaccines for middle- and high school–aged kids, and months more to test them in younger children. But some pediatricians say that concerns about the safety of the front-runner vaccines make the wait worthwhile.
Although most pediatricians believe the eventual vaccination of children will be crucial to subduing the COVID virus, they’re split on how fast to move toward that, says James Campbell, MD, professor of pediatrics at the University of Maryland’s Center for Vaccine Development and Global Health in Baltimore. Dr. Campbell and colleagues said it’s a matter of urgency to get the vaccines tested in kids, while others want to hold off on those trials until millions of adults have been safely vaccinated.
Much of the debate centers on two issues: the degree of harm COVID-19 causes children and the extent to which children are spreading the virus to their friends, teachers, parents and grandparents.
COVID-19’s impact on children represents a tiny fraction of the suffering and death experienced by vulnerable adults. Yet it would qualify as a pretty serious childhood disease, having caused 154 deaths and more than 7,500 hospitalizations as of Dec. 3 among aged people 19 years and younger in the United States. Those numbers rank it as worse than a typical year of influenza, and worse than diseases like mumps or hepatitis B in children before the vaccination era.
Studies thus far show that 1%-2% of children infected with the virus end up requiring intensive care, Stanley Plotkin, MD, professor emeritus of pediatrics at the University of Pennsylvania, Philadelphia told a federal panel. That’s in line with the percentage who become gravely ill as result of infections like Haemophilus influenzae type B, for which doctors have vaccinated children since the 1980s, he pointed out.
Dr. Campbell, who with colleagues has developed a plan for how to run pediatric COVID vaccine trials, pointed out that, “in a universe where COVID mainly affected children the way it’s affecting them now, and we had potential vaccines, people would be clamoring for them.”
The evidence that teens can transmit the disease is pretty clear, and transmission has been documented in children as young as 8. Fear of spread by children has been enough to close schools, and led the American Academy of Pediatrics to demand that children be quickly included in vaccine testing.
“The longer we take to start kids in trials, the longer it will take them to get vaccinated and to break the chains of transmission,” said Yvonne Maldonado, MD, a professor of pediatrics at Stanford (Calif.) University who chairs the AAP’s infectious disease committee. “If you want kids to go back to school and not have the teachers union terrified, you have to make sure they aren’t a risk.”
Other pediatricians worry that early pediatric trials could backfire. Cody Meissner, MD, chief of pediatric infectious diseases at Tufts Medical Center and a member of the FDA’s advisory committee on vaccines, is worried that whatever causes multisystem inflammatory syndrome in children, a rare but frightening COVID-related disorder, might also be triggered, however rarely, by vaccination.
Dr. Meissner abstained from the committee’s vote Thursday that supported, by a 17-4 vote, an emergency authorization of the Pfizer vaccine for people aged 16 years and older.
“I have trouble justifying it for children so unlikely to get the disease,” he said during debate on the measure.
But panel member Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, said the 16-years-and-up authorization would speed the vaccine’s testing in and approval for younger children. That is vital for the world’s protection from COVID-19, he said, since in the United States and most places “most vaccines are delivered early in life.”
While vaccines given to tens of thousands of people so far appear to be safe, the lack of understanding of the inflammatory syndrome means that children in any trials should be followed closely, said Emily Erbelding, MD, MPH, director of the division of microbiology and infectious diseases at the National Institute of Allergy and Infectious Diseases.
Under a 2003 law, vaccine companies are required eventually to test all their products on children. By late November, Pfizer had vaccinated approximately 100 children aged 12-15 years, said spokesperson Jerica Pitts.
Moderna has started enrolling 3,000 children aged 12 years and over in another clinical trial, and other companies have similar plans. Assuming the trials show the vaccines are safe and provide a good immune response, future tests could include progressively younger children, moving to, say, 6- to 12-year-olds next, then 2- to 6-year-olds. Eventually, trials could include younger toddlers and infants.
Similar step-down approaches were taken to test vaccines against human papillomavirus (HPV), influenza and other diseases in the past, Dr. Erbelding noted. Such trials are easiest to conduct when researchers know that a measurable immune response, like antibody levels in the blood, translates to effective protection against disease. Armed with such knowledge, they can see whether children were protected without them having to be exposed to the virus. Federal scientists hope to get that data from the Moderna and Pfizer adult vaccine trials, she said.
Vaccine trials geared to tweens or younger children may involve testing half-doses, which, if protective, would require less vaccine and might cause fewer incidents of sore arms and fevers that afflicted many who’ve received the Pfizer and Moderna vaccines, Dr. Campbell said.
But unless additional studies begin quickly, the window for having an FDA-authorized vaccine available before the next school year “will be closed even for our oldest children,” said Evan Anderson, MD, a pediatrics professor at Emory University, Atlanta. “Our younger children are almost certainly going into next school year without a vaccine option available for them.”
In the meantime, teachers are likely to be high on the priority list for vaccination. Protecting school staff could allow more schools to reopen even if most children can’t be vaccinated, Dr. Erbelding said.
Eventually, if the SARS-CoV-2 virus remains in circulation, governments may want to mandate childhood vaccination against the virus to protect them as they grow up and protect society as a whole, Dr. Plotkin said.
In the 1960s, Dr. Plotkin invented the rubella vaccine that has been given to hundreds of millions of children since. Like COVID-19, rubella – or German measles – is not usually a serious illness for children. But congenital rubella syndrome afflicted babies in the womb with blindness, deafness, developmental delays, and autism. Immunizing toddlers, which, in turn, protects their pregnant mothers, has indirectly prevented hundreds of thousands of such cases.
“We don’t want to use children to protect everyone in the community,” said Dr. Campbell. “But when you can protect both children and their community, that’s important.”
And while a coronavirus infection may not be bad for most children, missed school, absent friends, and distanced families have caused them immense suffering, he said.
“It’s a huge burden on a child to have their entire world flipped around,” Dr. Campbell said. “If vaccinating could help to flip it back, we should begin testing to see if that’s possible.”

Studies thus far show that 1%-2% of children infected with the virus end up requiring intensive care, Stanley Plotkin, MD, professor emeritus of pediatrics at the University of Pennsylvania, Philadelphia told a federal panel. That’s in line with the percentage who become gravely ill as result of infections like Haemophilus influenzae type B, for which doctors have vaccinated children since the 1980s, he pointed out.
Dr. Campbell, who with colleagues has developed a plan for how to run pediatric COVID vaccine trials, pointed out that, “in a universe where COVID mainly affected children the way it’s affecting them now, and we had potential vaccines, people would be clamoring for them.”
The evidence that teens can transmit the disease is pretty clear, and transmission has been documented in children as young as 8. Fear of spread by children has been enough to close schools, and led the American Academy of Pediatrics to demand that children be quickly included in vaccine testing.
“The longer we take to start kids in trials, the longer it will take them to get vaccinated and to break the chains of transmission,” said Yvonne Maldonado, MD, a professor of pediatrics at Stanford (Calif.) University who chairs the AAP’s infectious disease committee. “If you want kids to go back to school and not have the teachers union terrified, you have to make sure they aren’t a risk.”
Other pediatricians worry that early pediatric trials could backfire. Cody Meissner, MD, chief of pediatric infectious diseases at Tufts Medical Center and a member of the FDA’s advisory committee on vaccines, is worried that whatever causes multisystem inflammatory syndrome in children, a rare but frightening COVID-related disorder, might also be triggered, however rarely, by vaccination.
Dr. Meissner abstained from the committee’s vote Thursday that supported, by a 17-4 vote, an emergency authorization of the Pfizer vaccine for people aged 16 years and older.
“I have trouble justifying it for children so unlikely to get the disease,” he said during debate on the measure.
But panel member Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, said the 16-years-and-up authorization would speed the vaccine’s testing in and approval for younger children. That is vital for the world’s protection from COVID-19, he said, since in the United States and most places “most vaccines are delivered early in life.”
While vaccines given to tens of thousands of people so far appear to be safe, the lack of understanding of the inflammatory syndrome means that children in any trials should be followed closely, said Emily Erbelding, MD, MPH, director of the division of microbiology and infectious diseases at the National Institute of Allergy and Infectious Diseases.
Under a 2003 law, vaccine companies are required eventually to test all their products on children. By late November, Pfizer had vaccinated approximately 100 children aged 12-15 years, said spokesperson Jerica Pitts.
Moderna has started enrolling 3,000 children aged 12 years and over in another clinical trial, and other companies have similar plans. Assuming the trials show the vaccines are safe and provide a good immune response, future tests could include progressively younger children, moving to, say, 6- to 12-year-olds next, then 2- to 6-year-olds. Eventually, trials could include younger toddlers and infants.
Similar step-down approaches were taken to test vaccines against human papillomavirus (HPV), influenza and other diseases in the past, Dr. Erbelding noted. Such trials are easiest to conduct when researchers know that a measurable immune response, like antibody levels in the blood, translates to effective protection against disease. Armed with such knowledge, they can see whether children were protected without them having to be exposed to the virus. Federal scientists hope to get that data from the Moderna and Pfizer adult vaccine trials, she said.
Vaccine trials geared to tweens or younger children may involve testing half-doses, which, if protective, would require less vaccine and might cause fewer incidents of sore arms and fevers that afflicted many who’ve received the Pfizer and Moderna vaccines, Dr. Campbell said.
But unless additional studies begin quickly, the window for having an FDA-authorized vaccine available before the next school year “will be closed even for our oldest children,” said Evan Anderson, MD, a pediatrics professor at Emory University, Atlanta. “Our younger children are almost certainly going into next school year without a vaccine option available for them.”
In the meantime, teachers are likely to be high on the priority list for vaccination. Protecting school staff could allow more schools to reopen even if most children can’t be vaccinated, Dr. Erbelding said.
Eventually, if the SARS-CoV-2 virus remains in circulation, governments may want to mandate childhood vaccination against the virus to protect them as they grow up and protect society as a whole, Dr. Plotkin said.
In the 1960s, Dr. Plotkin invented the rubella vaccine that has been given to hundreds of millions of children since. Like COVID-19, rubella – or German measles – is not usually a serious illness for children. But congenital rubella syndrome afflicted babies in the womb with blindness, deafness, developmental delays, and autism. Immunizing toddlers, which, in turn, protects their pregnant mothers, has indirectly prevented hundreds of thousands of such cases.
“We don’t want to use children to protect everyone in the community,” said Dr. Campbell. “But when you can protect both children and their community, that’s important.”
And while a coronavirus infection may not be bad for most children, missed school, absent friends, and distanced families have caused them immense suffering, he said.
“It’s a huge burden on a child to have their entire world flipped around,” Dr. Campbell said. “If vaccinating could help to flip it back, we should begin testing to see if that’s possible.”

COVID-19 vaccines: Safe for immunocompromised patients?
Coronavirus vaccines have become a reality, as they are now being approved and authorized for use in a growing number of countries including the United States. The U.S. Food and Drug Administration has just issued emergency authorization for the use of the COVID-19 vaccine produced by Pfizer and BioNTech. Close behind is the vaccine developed by Moderna, which has also applied to the FDA for emergency authorization.
The efficacy of a two-dose administration of the vaccine has been pegged at 95.0%, and the FDA has said that the 95% credible interval for the vaccine efficacy was 90.3%-97.6%. But as with many initial clinical trials, whether for drugs or vaccines, not all populations were represented in the trial cohort, including individuals who are immunocompromised. At the current time, it is largely unknown how safe or effective the vaccine may be in this large population, many of whom are at high risk for serious COVID-19 complications.
At a special session held during the recent annual meeting of the American Society of Hematology, Anthony Fauci, MD, the nation’s leading infectious disease expert, said that individuals with compromised immune systems, whether because of chemotherapy or a bone marrow transplant, should plan to be vaccinated when the opportunity arises.
In response to a question from ASH President Stephanie J. Lee, MD, of the Fred Hutchinson Cancer Center, Seattle, Dr. Fauci emphasized that, despite being excluded from clinical trials, this population should get vaccinated. “I think we should recommend that they get vaccinated,” he said. “I mean, it is clear that, if you are on immunosuppressive agents, history tells us that you’re not going to have as robust a response as if you had an intact immune system that was not being compromised. But some degree of immunity is better than no degree of immunity.”
That does seem to be the consensus among experts who spoke in interviews: that as long as these are not live attenuated vaccines, they hold no specific risk to an immunocompromised patient, other than any factors specific to the individual that could be a contraindication.
“Patients, family members, friends, and work contacts should be encouraged to receive the vaccine,” said William Stohl, MD, PhD, chief of the division of rheumatology at the University of Southern California, Los Angeles. “Clinicians should advise patients to obtain the vaccine sooner rather than later.”
Kevin C. Wang, MD, PhD, of the department of dermatology at Stanford (Calif.) University, agreed. “I am 100% with Dr. Fauci. Everyone should get the vaccine, even if it may not be as effective,” he said. “I would treat it exactly like the flu vaccines that we recommend folks get every year.”
Dr. Wang noted that he couldn’t think of any contraindications unless the immunosuppressed patients have a history of severe allergic reactions to prior vaccinations. “But I would even say patients with history of cancer, upon recommendation of their oncologists, are likely to be suitable candidates for the vaccine,” he added. “I would say clinicians should approach counseling the same way they counsel patients for the flu vaccine, and as far as I know, there are no concerns for systemic drugs commonly used in dermatology patients.”
However, guidance has not yet been issued from either the FDA or the Centers for Disease Control and Prevention regarding the use of the vaccine in immunocompromised individuals. Given the lack of data, the FDA has said that “it will be something that providers will need to consider on an individual basis,” and that individuals should consult with physicians to weigh the potential benefits and potential risks.
The CDC’s Advisory Committee on Immunization Practices has said that clinicians need more guidance on whether to use the vaccine in pregnant or breastfeeding women, the immunocompromised, or those who have a history of allergies. The CDC itself has not yet released its formal guidance on vaccine use.
COVID-19 vaccines
Vaccines typically require years of research and testing before reaching the clinic, but this year researchers embarked on a global effort to develop safe and effective coronavirus vaccines in record time. Both the Pfizer/BioNTech and Moderna vaccines have only a few months of phase 3 clinical trial data, so much remains unknown about them, including their duration of effect and any long-term safety signals. In addition to excluding immunocompromised individuals, the clinical trials did not include children or pregnant women, so data are lacking for several population subgroups.
But these will not be the only vaccines available, as the pipeline is already becoming crowded. U.S. clinical trial data from a vaccine jointly being developed by Oxford-AstraZeneca, could potentially be ready, along with a request for FDA emergency use authorization, by late January 2021.
In addition, China and Russia have released vaccines, and there are currently 61 vaccines being investigated in clinical trials and at least 85 preclinical products under active investigation.
The vaccine candidates are using both conventional and novel mechanisms of action to elicit an immune response in patients. Conventional methods include attenuated inactivated (killed) virus and recombinant viral protein vaccines to develop immunity. Novel approaches include replication-deficient, adenovirus vector-based vaccines that contain the viral protein, and mRNA-based vaccines, such as the Pfizer and Moderna vaccines, that encode for a SARS-CoV-2 spike protein.
“The special vaccine concern for immunocompromised individuals is introduction of a live virus,” Dr. Stohl said. “Neither the Moderna nor Pfizer vaccines are live viruses, so there should be no special contraindication for such individuals.”
Live vaccine should be avoided in immunocompromised patients, and currently, live SARS-CoV-2 vaccines are only being developed in India and Turkey.
It is not unusual for vaccine trials to begin with cohorts that exclude participants with various health conditions, including those who are immunocompromised. These groups are generally then evaluated in phase 4 trials, or postmarketing surveillance. While the precise number of immunosuppressed adults in the United States is not known, the numbers are believed to be rising because of increased life expectancy among immunosuppressed adults as a result of advances in treatment and new and wider indications for therapies that can affect the immune system.
According to data from the 2013 National Health Interview Survey, an estimated 2.7% of U.S. adults are immunosuppressed. This population covers a broad array of health conditions and medical specialties; people living with inflammatory or autoimmune conditions, such as inflammatory rheumatic diseases (rheumatoid arthritis, axial spondyloarthritis, lupus); inflammatory bowel disease (Crohn’s disease and ulcerative colitis); psoriasis; multiple sclerosis; organ transplant recipients; patients undergoing chemotherapy; and life-long immunosuppression attributable to HIV infection.
As the vaccines begin to roll out and become available, how should clinicians advise their patients, in the absence of any clinical trial data?
Risk vs. benefit
Gilaad Kaplan, MD, MPH, a gastroenterologist and professor of medicine at the University of Calgary (Alta.), noted that the inflammatory bowel disease (IBD) community has dealt with tremendous anxiety during the pandemic because many are immunocompromised because of the medications they use to treat their disease.
“For example, many patients with IBD are on biologics like anti-TNF [tumor necrosis factor] therapies, which are also used in other immune-mediated inflammatory diseases such as rheumatoid arthritis,” he said. “Understandably, individuals with IBD on immunosuppressive medications are concerned about the risk of severe complications due to COVID-19.”
The entire IBD community, along with the world, celebrated the announcement that multiple vaccines are protective against SARS-CoV-2, he noted. “Vaccines offer the potential to reduce the spread of COVID-19, allowing society to revert back to normalcy,” Dr. Kaplan said. “Moreover, for vulnerable populations, including those who are immunocompromised, vaccines offer the potential to directly protect them from the morbidity and mortality associated with COVID-19.”
That said, even though the news of vaccines are extremely promising, some cautions must be raised regarding their use in immunocompromised populations, such as persons with IBD. “The current trials, to my knowledge, did not include immunocompromised individuals and thus, we can only extrapolate from what we know from other trials of different vaccines,” he explained. “We know from prior vaccines studies that the immune response following vaccination is less robust in those who are immunocompromised as compared to a healthy control population.”
Dr. Kaplan also pointed to recent reports of allergic reactions that have been reported in healthy individuals. “We don’t know whether side effects, like allergic reactions, may be different in unstudied populations,” he said. “Thus, the medical and scientific community should prioritize clinical studies of safety and effectiveness of COVID-19 vaccines in immunocompromised populations.”
So, what does this mean for an individual with an immune-mediated inflammatory disease like Crohn’s disease or ulcerative colitis who is immunocompromised? Dr. Kaplan explained that it is a balance between the potential harm of being infected with COVID-19 and the uncertainty of receiving a vaccine in an understudied population. For those who are highly susceptible to dying from COVID-19, such as an older adult with IBD, or someone who faces high exposure, such as a health care worker, the potential protection of the vaccine greatly outweighs the uncertainty.
“However, for individuals who are at otherwise lower risk – for example, young and able to work from home – then waiting a few extra months for postmarketing surveillance studies in immunocompromised populations may be a reasonable approach, as long as these individuals are taking great care to avoid infection,” he said.
No waiting needed
Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, feels that the newly approved vaccine should be safe for most of his patients.
“Patients with psoriatic disease should get the mRNA-based COVID-19 vaccine as soon as possible based on eligibility as determined by the CDC and local public health officials,” he said. “It is not a live vaccine, and therefore patients on biologics or other immune-modulating or immune-suppressing treatment can receive it.”
However, the impact of psoriasis treatment on immune response to the mRNA-based vaccines is not known. Dr. Gelfand noted that, extrapolating from the vaccine literature, there is some evidence that methotrexate reduces response to the influenza vaccine. “However, the clinical significance of this finding is not clear,” he said. “Since the mRNA vaccine needs to be taken twice, a few weeks apart, I do not recommend interrupting or delaying treatment for psoriatic disease while undergoing vaccination for COVID-19.”
Given the reports of allergic reactions, he added that it is advisable for patients with a history of life-threatening allergic reactions such as anaphylaxis or who have been advised to carry an epinephrine autoinjector, to talk with their health care provider to determine if COVID-19 vaccination is medically appropriate.
The National Psoriasis Foundation has issued guidance on COVID-19, explained Steven R. Feldman, MD, PhD, professor of dermatology, pathology, and social sciences & health policy at Wake Forest University, Winston-Salem, N.C., who is also a member of the committee that is working on those guidelines and keeping them up to date. “We are in the process of updating the guidelines with information on COVID vaccines,” he said.
He agreed that there are no contraindications for psoriasis patients to receive the vaccine, regardless of whether they are on immunosuppressive treatment, even though definitive data are lacking. “Fortunately, there’s a lot of good data coming out of Italy that patients with psoriasis on biologics do not appear to be at increased risk of getting COVID or of having worse outcomes from COVID,” he said.
Patients are going to ask about the vaccines, and when counseling them, clinicians should discuss the available data, the residual uncertainty, and patients’ concerns should be considered, Dr. Feldman explained. “There may be some concern that steroids and cyclosporine would reduce the effectiveness of vaccines, but there is no concern that any of the drugs would cause increased risk from nonlive vaccines.”
He added that there is evidence that “patients on biologics who receive nonlive vaccines do develop antibody responses and are immunized.”
Boosting efficacy
Even prior to making their announcement, the American College of Rheumatology had said that they would endorse the vaccine for all patients, explained rheumatologist Brett Smith, DO, from Blount Memorial Physicians Group and East Tennessee Children’s Hospital, Alcoa. “The vaccine is safe for all patients, but the problem may be that it’s not as effective,” he said. “But we don’t know that because it hasn’t been tested.”
With other vaccines, biologic medicines are held for 2 weeks before and afterwards, to get the best response. “But some patients don’t want to stop the medication,” Dr. Smith said. “They are afraid that their symptoms will return.”
As for counseling patients as to whether they should receive this vaccine, he explained that he typically doesn’t try to sway patients one way or another until they are really high risk. “When I counsel, it really depends on the individual situation. And for this vaccine, we have to be open to the fact that many people have already made up their mind.”
There are a lot of questions regarding the vaccine. One is the short time frame of development. “Vaccines typically take 6-10 years to come on the market, and this one is now available after a 3-month study,” Dr. Smith said. “Some have already decided that it’s too new for them.”
The process is also new, and patients need to understand that it doesn’t contain an active virus and “you can’t catch coronavirus from it.”
Dr. Smith also explained that, because the vaccine may be less effective in a person using biologic therapies, there is currently no information available on repeat vaccination. “These are all unanswered questions,” he said. “If the antibodies wane in a short time, can we be revaccinated and in what time frame? We just don’t know that yet.”
Marcelo Bonomi, MD, a medical oncologist from The Ohio State University Comprehensive Cancer Center, Columbus, explained that one way to ensure a more optimal response to the vaccine would be to wait until the patient has finished chemotherapy.* “The vaccine can be offered at that time, and in the meantime, they can take other steps to avoid infection,” he said. “If they are very immunosuppressed, it isn’t worth trying to give the vaccine.”
Cancer patients should be encouraged to stay as healthy as possible, and to wear masks and social distance. “It’s a comprehensive approach. Eat healthy, avoid alcohol and tobacco, and exercise. [These things] will help boost the immune system,” Dr. Bonomi said. “Family members should be encouraged to get vaccinated, which will help them avoid infection and exposing the patient.”
Jim Boonyaratanakornkit, MD, PhD, an infectious disease specialist who cares for cancer patients at the Fred Hutchinson Cancer Research Center, agreed. “Giving a vaccine right after a transplant is a futile endeavor,” he said. “We need to wait 6 months to have an immune response.”
He pointed out there may be a continuing higher number of cases, with high levels peaking in Washington in February and March. “Close friends and family should be vaccinated if possible,” he said, “which will help interrupt transmission.”
The vaccines are using new platforms that are totally different, and there is no clear data as to how long the antibodies will persist. “We know that they last for at least 4 months,” said Dr. Boonyaratanakornkit. “We don’t know what level of antibody will protect them from COVID-19 infection. Current studies are being conducted, but we don’t have that information for anyone yet.”

The vaccines are using new platforms that are totally different, and there is no clear data as to how long the antibodies will persist. “We know that they last for at least 4 months,” said Dr. Boonyaratanakornkit. “We don’t know what level of antibody will protect them from COVID-19 infection. Current studies are being conducted, but we don’t have that information for anyone yet.”

Coronavirus vaccines have become a reality, as they are now being approved and authorized for use in a growing number of countries including the United States. The U.S. Food and Drug Administration has just issued emergency authorization for the use of the COVID-19 vaccine produced by Pfizer and BioNTech. Close behind is the vaccine developed by Moderna, which has also applied to the FDA for emergency authorization.
The efficacy of a two-dose administration of the vaccine has been pegged at 95.0%, and the FDA has said that the 95% credible interval for the vaccine efficacy was 90.3%-97.6%. But as with many initial clinical trials, whether for drugs or vaccines, not all populations were represented in the trial cohort, including individuals who are immunocompromised. At the current time, it is largely unknown how safe or effective the vaccine may be in this large population, many of whom are at high risk for serious COVID-19 complications.
At a special session held during the recent annual meeting of the American Society of Hematology, Anthony Fauci, MD, the nation’s leading infectious disease expert, said that individuals with compromised immune systems, whether because of chemotherapy or a bone marrow transplant, should plan to be vaccinated when the opportunity arises.
In response to a question from ASH President Stephanie J. Lee, MD, of the Fred Hutchinson Cancer Center, Seattle, Dr. Fauci emphasized that, despite being excluded from clinical trials, this population should get vaccinated. “I think we should recommend that they get vaccinated,” he said. “I mean, it is clear that, if you are on immunosuppressive agents, history tells us that you’re not going to have as robust a response as if you had an intact immune system that was not being compromised. But some degree of immunity is better than no degree of immunity.”
That does seem to be the consensus among experts who spoke in interviews: that as long as these are not live attenuated vaccines, they hold no specific risk to an immunocompromised patient, other than any factors specific to the individual that could be a contraindication.
“Patients, family members, friends, and work contacts should be encouraged to receive the vaccine,” said William Stohl, MD, PhD, chief of the division of rheumatology at the University of Southern California, Los Angeles. “Clinicians should advise patients to obtain the vaccine sooner rather than later.”
Kevin C. Wang, MD, PhD, of the department of dermatology at Stanford (Calif.) University, agreed. “I am 100% with Dr. Fauci. Everyone should get the vaccine, even if it may not be as effective,” he said. “I would treat it exactly like the flu vaccines that we recommend folks get every year.”
Dr. Wang noted that he couldn’t think of any contraindications unless the immunosuppressed patients have a history of severe allergic reactions to prior vaccinations. “But I would even say patients with history of cancer, upon recommendation of their oncologists, are likely to be suitable candidates for the vaccine,” he added. “I would say clinicians should approach counseling the same way they counsel patients for the flu vaccine, and as far as I know, there are no concerns for systemic drugs commonly used in dermatology patients.”
However, guidance has not yet been issued from either the FDA or the Centers for Disease Control and Prevention regarding the use of the vaccine in immunocompromised individuals. Given the lack of data, the FDA has said that “it will be something that providers will need to consider on an individual basis,” and that individuals should consult with physicians to weigh the potential benefits and potential risks.
The CDC’s Advisory Committee on Immunization Practices has said that clinicians need more guidance on whether to use the vaccine in pregnant or breastfeeding women, the immunocompromised, or those who have a history of allergies. The CDC itself has not yet released its formal guidance on vaccine use.
COVID-19 vaccines
Vaccines typically require years of research and testing before reaching the clinic, but this year researchers embarked on a global effort to develop safe and effective coronavirus vaccines in record time. Both the Pfizer/BioNTech and Moderna vaccines have only a few months of phase 3 clinical trial data, so much remains unknown about them, including their duration of effect and any long-term safety signals. In addition to excluding immunocompromised individuals, the clinical trials did not include children or pregnant women, so data are lacking for several population subgroups.
But these will not be the only vaccines available, as the pipeline is already becoming crowded. U.S. clinical trial data from a vaccine jointly being developed by Oxford-AstraZeneca, could potentially be ready, along with a request for FDA emergency use authorization, by late January 2021.
In addition, China and Russia have released vaccines, and there are currently 61 vaccines being investigated in clinical trials and at least 85 preclinical products under active investigation.
The vaccine candidates are using both conventional and novel mechanisms of action to elicit an immune response in patients. Conventional methods include attenuated inactivated (killed) virus and recombinant viral protein vaccines to develop immunity. Novel approaches include replication-deficient, adenovirus vector-based vaccines that contain the viral protein, and mRNA-based vaccines, such as the Pfizer and Moderna vaccines, that encode for a SARS-CoV-2 spike protein.
“The special vaccine concern for immunocompromised individuals is introduction of a live virus,” Dr. Stohl said. “Neither the Moderna nor Pfizer vaccines are live viruses, so there should be no special contraindication for such individuals.”
Live vaccine should be avoided in immunocompromised patients, and currently, live SARS-CoV-2 vaccines are only being developed in India and Turkey.
It is not unusual for vaccine trials to begin with cohorts that exclude participants with various health conditions, including those who are immunocompromised. These groups are generally then evaluated in phase 4 trials, or postmarketing surveillance. While the precise number of immunosuppressed adults in the United States is not known, the numbers are believed to be rising because of increased life expectancy among immunosuppressed adults as a result of advances in treatment and new and wider indications for therapies that can affect the immune system.
According to data from the 2013 National Health Interview Survey, an estimated 2.7% of U.S. adults are immunosuppressed. This population covers a broad array of health conditions and medical specialties; people living with inflammatory or autoimmune conditions, such as inflammatory rheumatic diseases (rheumatoid arthritis, axial spondyloarthritis, lupus); inflammatory bowel disease (Crohn’s disease and ulcerative colitis); psoriasis; multiple sclerosis; organ transplant recipients; patients undergoing chemotherapy; and life-long immunosuppression attributable to HIV infection.
As the vaccines begin to roll out and become available, how should clinicians advise their patients, in the absence of any clinical trial data?
Risk vs. benefit
Gilaad Kaplan, MD, MPH, a gastroenterologist and professor of medicine at the University of Calgary (Alta.), noted that the inflammatory bowel disease (IBD) community has dealt with tremendous anxiety during the pandemic because many are immunocompromised because of the medications they use to treat their disease.
“For example, many patients with IBD are on biologics like anti-TNF [tumor necrosis factor] therapies, which are also used in other immune-mediated inflammatory diseases such as rheumatoid arthritis,” he said. “Understandably, individuals with IBD on immunosuppressive medications are concerned about the risk of severe complications due to COVID-19.”
The entire IBD community, along with the world, celebrated the announcement that multiple vaccines are protective against SARS-CoV-2, he noted. “Vaccines offer the potential to reduce the spread of COVID-19, allowing society to revert back to normalcy,” Dr. Kaplan said. “Moreover, for vulnerable populations, including those who are immunocompromised, vaccines offer the potential to directly protect them from the morbidity and mortality associated with COVID-19.”
That said, even though the news of vaccines are extremely promising, some cautions must be raised regarding their use in immunocompromised populations, such as persons with IBD. “The current trials, to my knowledge, did not include immunocompromised individuals and thus, we can only extrapolate from what we know from other trials of different vaccines,” he explained. “We know from prior vaccines studies that the immune response following vaccination is less robust in those who are immunocompromised as compared to a healthy control population.”
Dr. Kaplan also pointed to recent reports of allergic reactions that have been reported in healthy individuals. “We don’t know whether side effects, like allergic reactions, may be different in unstudied populations,” he said. “Thus, the medical and scientific community should prioritize clinical studies of safety and effectiveness of COVID-19 vaccines in immunocompromised populations.”
So, what does this mean for an individual with an immune-mediated inflammatory disease like Crohn’s disease or ulcerative colitis who is immunocompromised? Dr. Kaplan explained that it is a balance between the potential harm of being infected with COVID-19 and the uncertainty of receiving a vaccine in an understudied population. For those who are highly susceptible to dying from COVID-19, such as an older adult with IBD, or someone who faces high exposure, such as a health care worker, the potential protection of the vaccine greatly outweighs the uncertainty.
“However, for individuals who are at otherwise lower risk – for example, young and able to work from home – then waiting a few extra months for postmarketing surveillance studies in immunocompromised populations may be a reasonable approach, as long as these individuals are taking great care to avoid infection,” he said.
No waiting needed
Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, feels that the newly approved vaccine should be safe for most of his patients.
“Patients with psoriatic disease should get the mRNA-based COVID-19 vaccine as soon as possible based on eligibility as determined by the CDC and local public health officials,” he said. “It is not a live vaccine, and therefore patients on biologics or other immune-modulating or immune-suppressing treatment can receive it.”
However, the impact of psoriasis treatment on immune response to the mRNA-based vaccines is not known. Dr. Gelfand noted that, extrapolating from the vaccine literature, there is some evidence that methotrexate reduces response to the influenza vaccine. “However, the clinical significance of this finding is not clear,” he said. “Since the mRNA vaccine needs to be taken twice, a few weeks apart, I do not recommend interrupting or delaying treatment for psoriatic disease while undergoing vaccination for COVID-19.”
Given the reports of allergic reactions, he added that it is advisable for patients with a history of life-threatening allergic reactions such as anaphylaxis or who have been advised to carry an epinephrine autoinjector, to talk with their health care provider to determine if COVID-19 vaccination is medically appropriate.
The National Psoriasis Foundation has issued guidance on COVID-19, explained Steven R. Feldman, MD, PhD, professor of dermatology, pathology, and social sciences & health policy at Wake Forest University, Winston-Salem, N.C., who is also a member of the committee that is working on those guidelines and keeping them up to date. “We are in the process of updating the guidelines with information on COVID vaccines,” he said.
He agreed that there are no contraindications for psoriasis patients to receive the vaccine, regardless of whether they are on immunosuppressive treatment, even though definitive data are lacking. “Fortunately, there’s a lot of good data coming out of Italy that patients with psoriasis on biologics do not appear to be at increased risk of getting COVID or of having worse outcomes from COVID,” he said.
Patients are going to ask about the vaccines, and when counseling them, clinicians should discuss the available data, the residual uncertainty, and patients’ concerns should be considered, Dr. Feldman explained. “There may be some concern that steroids and cyclosporine would reduce the effectiveness of vaccines, but there is no concern that any of the drugs would cause increased risk from nonlive vaccines.”
He added that there is evidence that “patients on biologics who receive nonlive vaccines do develop antibody responses and are immunized.”
Boosting efficacy
Even prior to making their announcement, the American College of Rheumatology had said that they would endorse the vaccine for all patients, explained rheumatologist Brett Smith, DO, from Blount Memorial Physicians Group and East Tennessee Children’s Hospital, Alcoa. “The vaccine is safe for all patients, but the problem may be that it’s not as effective,” he said. “But we don’t know that because it hasn’t been tested.”
With other vaccines, biologic medicines are held for 2 weeks before and afterwards, to get the best response. “But some patients don’t want to stop the medication,” Dr. Smith said. “They are afraid that their symptoms will return.”
As for counseling patients as to whether they should receive this vaccine, he explained that he typically doesn’t try to sway patients one way or another until they are really high risk. “When I counsel, it really depends on the individual situation. And for this vaccine, we have to be open to the fact that many people have already made up their mind.”
There are a lot of questions regarding the vaccine. One is the short time frame of development. “Vaccines typically take 6-10 years to come on the market, and this one is now available after a 3-month study,” Dr. Smith said. “Some have already decided that it’s too new for them.”
The process is also new, and patients need to understand that it doesn’t contain an active virus and “you can’t catch coronavirus from it.”
Dr. Smith also explained that, because the vaccine may be less effective in a person using biologic therapies, there is currently no information available on repeat vaccination. “These are all unanswered questions,” he said. “If the antibodies wane in a short time, can we be revaccinated and in what time frame? We just don’t know that yet.”
Marcelo Bonomi, MD, a medical oncologist from The Ohio State University Comprehensive Cancer Center, Columbus, explained that one way to ensure a more optimal response to the vaccine would be to wait until the patient has finished chemotherapy.* “The vaccine can be offered at that time, and in the meantime, they can take other steps to avoid infection,” he said. “If they are very immunosuppressed, it isn’t worth trying to give the vaccine.”
Cancer patients should be encouraged to stay as healthy as possible, and to wear masks and social distance. “It’s a comprehensive approach. Eat healthy, avoid alcohol and tobacco, and exercise. [These things] will help boost the immune system,” Dr. Bonomi said. “Family members should be encouraged to get vaccinated, which will help them avoid infection and exposing the patient.”
Jim Boonyaratanakornkit, MD, PhD, an infectious disease specialist who cares for cancer patients at the Fred Hutchinson Cancer Research Center, agreed. “Giving a vaccine right after a transplant is a futile endeavor,” he said. “We need to wait 6 months to have an immune response.”

Parents favored virtual learning over in-person school attendance
Parents of school-aged children were generally more comfortable with full-time virtual learning in schools in the fall of 2020, compared with full-capacity in-person attendance, according to a survey conducted in July.
Those of racial/ethnic minorities, however, “were less likely to feel that schools should reopen for all students and were more concerned about” several aspects of in-person instruction than were White parents, Leah K. Gilbert, MD, and associates at the Centers for Disease Control and Prevention’s COVID-19 Response Team said in the Morbidity and Mortality Weekly Report.
A slim majority, just under 53% of the 858 parents surveyed, said that they were very or somewhat comfortable with their children returning to schools that were reopening at full capacity, while almost 70% said they were very/somewhat comfortable with schools going exclusively with virtual learning, the investigators reported.
The question about full-capacity attendance in particular showed considerable variation by race and ethnicity, with 57% of White parents saying they were very/somewhat comfortable, versus 53% of Hispanic or Latino parents, 43% of Black parents, and 32.5% of parents of other races/ethnicities (American Indian/Alaska Native, Asian, or multiracial).
Comfort levels were closer regarding virtual learning: Parents of other races/ethnicities were lowest at 67% and Black parents were highest at 73%. When asked about schools reopening at 50% capacity and 50% virtual learning, Black parents were again lowest at 58% with strong or moderate comfort and White parents were highest at 68%, Dr. Gilbert and associates said.
“Although the majority of parent respondents had concerns about both school reopening for in-person instruction and virtual learning, the perceived risk for SARS-CoV-2 infection and poor health outcomes might account for the differences in parental attitudes and concerns by race and ethnicity,” they wrote.
