FDA OKs emergency use of Pfizer COVID-19 vaccine
The much-anticipated emergency use authorization (EUA) of this vaccine — the first such approval in the United States — was greeted with optimism by infectious disease and pulmonary experts, although unanswered questions remain regarding use in people with allergic hypersensitivity, safety in pregnant women, and how smooth distribution will be.
“I am delighted. This is a first, firm step on a long path to getting this COVID pandemic under control,” William Schaffner, MD, professor of infectious diseases at the Vanderbilt University School of Medicine in Nashville, Tennessee, said in an interview.
The FDA gave the green light after the December 10 recommendation from the agency’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting. The committee voted 17-4 in favor of the emergency authorization.
The COVID-19 vaccine is “going to have a major impact here in the US. I’m very optimistic about it,” Dial Hewlett, MD, a spokesperson for the Infectious Diseases Society of American (IDSA), told this news organization.
Daniel Culver, DO, chair of medicine at the Cleveland Clinic in Ohio, is likewise hopeful. “My understanding is that supplies of the vaccine are already in place in hubs and will be shipped relatively quickly. The hope would be we can start vaccinating people as early as next week.”
Allergic reactions reported in the UK
After vaccinations with the Pfizer vaccine began in the UK on December 8, reports surfaced of two healthcare workers who experienced allergic reactions. They have since recovered, but officials warned that people with a history of severe allergic reactions should not receive the Pfizer vaccine at this time.
“For the moment, they are asking people who have had notable allergic reactions to step aside while this is investigated. It shows you that the system is working,” Schaffner said.
Both vaccine recipients who experienced anaphylaxis carried EpiPens, as they were at high risk for allergic reactions, Hewlett said. Also, if other COVID-19 vaccines are approved for use in the future, people allergic to the Pfizer vaccine might have another option, he added.
Reassuring role models
Schaffner supports the CDC Advisory Committee on Immunization Practices (ACIP) decision to start vaccinations with healthcare workers and residents of long-term care facilities.
“Vaccinating healthcare workers, in particular, will be a model for the general public,” said Schaffner, who is also a former member of the IDSA board of directors. “If they see those of us in white coats and blue scrubs lining up for the vaccine, that will provide confidence.”
To further increase acceptance of the COVID-19 vaccine, public health officials need to provide information and reassure the general public, Schaffner said.
Hewlett agreed. “I know there are a lot of people in the population who are very hesitant about vaccines. As infection disease specialists and people in public health, we are trying to allay a lot of concerns people have.”
Reassurance will be especially important in minority communities. “They have been disproportionately affected by the virus, and they have a traditional history of not being optimally vaccinated,” Schaffner said. “We need to reach them in particular with good information and reassurance…so they can make good decisions for themselves and their families.”
No vaccine is 100% effective or completely free of side effects. “There is always a chance there can be adverse reactions, but we think for the most part this is going to be a safe and effective vaccine,” said Hewlett, medical director at the Division of Disease Control and deputy to commissioner of health at the Westchester County Department of Health in White Plains, New York.
Distribution: Smooth or full of strife?
In addition to the concern that some people will not take advantage of vaccination against COVID-19, there could be vaccine supply issues down the road, Schaffner said.
Culver agreed. “In the early phases, I expect that there will be some kinks to work out, but because the numbers are relatively small, this should be okay,” he said.
“I think when we start to get into larger-scale vaccination programs — the supply chain, transport, and storage will be a Herculean undertaking,” Culver added. “It will take careful coordination between healthcare providers, distributors, suppliers, and public health officials to pull this off.”
Planning and distribution also should focus beyond US borders. Any issues in vaccine distribution or administration in the United States “will only be multiplied in several other parts of the world,” Culver said. Because COVID-19 is a pandemic, “we need to think about vaccinating globally.”
Investigating adverse events
Adverse events common to vaccinations in general — injection site pain, headaches, and fever — would not be unexpected with the COVID-19 vaccines. However, experts remain concerned that other, unrelated adverse events might be erroneously attributed to vaccination. For example, if a fall, heart attack, or death occurs within days of immunization, some might immediately blame the vaccine product.
“It’s important to remember that any new, highly touted medical therapy like this will receive a lot of scrutiny, so it would be unusual not to hear about something happening to somebody,” Culver said. Vaccine companies and health agencies will be carefully evaluating any reported adverse events to ensure no safety signal was missed in the trials.
“Fortunately, there are systems in place to investigate these events immediately,” Schaffner said.
Pregnancy recommendations pending
One question still looms: Is the COVID-19 vaccination safe for pregnant women? This isn’t just a question for the general public, either, Schaffner said. He estimated that about 70 percent of healthcare workers are women, and data suggests about 300,000 of these healthcare workers are pregnant.
“The CDC’s Advisory Committee on Immunization Practices will speak to that just as soon as the EUA is issued,” he added.
Patients are asking Culver about the priority order for vaccination. He said it’s difficult to provide firm guidance at this point.
People also have “lingering skepticism” about whether vaccine development was done in a prudent way, Culver said. Some people question whether the Pfizer vaccine and others were rushed to market. “So we try to spend time with the patients, reassuring them that all the usual safety evaluations were carefully done,” he said.
Another concern is whether mRNA vaccines can interact with human DNA. “The quick, short, and definitive answer is no,” Schaffner said. The m stands for messenger — the vaccines transmit information. "Once it gets into a cell, the mRNA does not go anywhere near the DNA, and once it transmits its information to the cell appropriately, it gets metabolized, and we excrete all the remnants."
Hewlett pointed out that investigations and surveillance will continue. Because this is an EUA and not full approval, “that essentially means they will still be obligated to collect a lot more data than they would ordinarily,” he said.
How long immunoprotection will last also remains an unknown. “The big question left on the table now is the durability,” Culver said. “Of course, we won’t know the answer to that for quite some time.”
Schaffner and Culver have disclosed no relevant financial relationships. Hewlett was an employee of Pfizer until mid-2019. His previous work as Pfizer’s senior medical director of global medical product evaluation was not associated with development of the COVID-19 vaccine.

COVID-19 vaccines: Preparing for patient questions
With U.S. approval of one coronavirus vaccine likely imminent and approval of a second one expected soon after, physicians will likely be deluged with questions. Public attitudes about the vaccines vary by demographics, with a recent poll showing that men and older adults are more likely to choose vaccination, and women and people of color evincing more wariness.
Although the reasons for reluctance may vary, questions from patient will likely be similar. Some are related to the “warp speed” language about the vaccines. Other concerns arise from the fact that the platform – mRNA – has not been used in human vaccines before. And as with any vaccine, there are rumors and false claims making the rounds on social media.
In anticipation of the most common questions physicians may encounter, two experts, Krutika Kuppalli, MD, assistant professor of medicine in the division of infectious diseases at the Medical University of South Carolina, Charleston, and Angela Rasmussen, PhD, virologist and nonresident affiliate at Georgetown University’s Center for Global Health Science and Security, Washington, talked in an interview about what clinicians can expect and what evidence-based – as well as compassionate – answers might look like.
Q: Will this vaccine give me COVID-19?
“There is not an intact virus in there,” Dr. Rasmussen said. The mRNA-based vaccines cannot cause COVID-19 because they don’t use any part of the coronavirus itself. Instead, the Moderna and Pfizer vaccines contain manufactured mRNA molecules that carry the instructions for building the virus’ spike protein. After vaccine administration, the recipient’s own cells take up this mRNA, use it to build this bit of protein, and display it on their surfaces. The foreign protein flag triggers the immune system response.
The mRNA does not enter the cell nucleus or interact with the recipient’s DNA. And because it’s so fragile, it degrades quite quickly. To keep that from happening before cell entry, the mRNAs are cushioned in protective fats.
Q: Was this vaccine made too quickly?
“People have been working on this platform for 30 years, so it’s not that this is brand new,” Dr. Kuppalli said.
Researchers began working on mRNA vaccines in the 1990s. Technological developments in the last decade have meant that their use has become feasible, and they have been tested in animals against many viral diseases. The mRNA vaccines are attractive because they’re expected to be safe and easily manufactured from common materials. That’s what we’ve seen in the COVID-19 pandemic, the Centers for Disease Control and Prevention says on its website. Design of the spike protein mRNA component began as soon as the viral genome became available in January.
Usually, rolling out a vaccine takes years, so less than a year under a program called Operation Warp Speed can seem like moving too fast, Dr. Rasmussen acknowledged. “The name has given people the impression that by going at warp speed, we’re cutting all the corners. [But] the reality is that Operation Warp Speed is mostly for manufacturing and distribution.”
What underlies the speed is a restructuring of the normal vaccine development process, Dr. Kuppalli said. The same phases of development – animal testing, a small initial human phase, a second for safety testing, a third large phase for efficacy – were all conducted as for any vaccine. But in this case, some phases were completed in parallel, rather than sequentially. This approach has proved so successful that there is already talk about making it the model for developing future vaccines.
Two other factors contributed to the speed, said Dr. Kuppalli and Dr. Rasmussen. First, gearing up production can slow a rollout, but with these vaccines, companies ramped up production even before anyone knew if the vaccines would work – the “warp speed” part. The second factor has been the large number of cases, making exposures more likely and thus accelerating the results of the efficacy trials. “There is so much COVID being transmitted everywhere in the United States that it did not take long to hit the threshold of events to read out phase 3,” Dr. Rasmussen said.
Q: This vaccine has never been used in humans. How do we know it’s safe?
The Pfizer phase 3 trial included more than 43,000 people, and Moderna’s had more than 30,000. The first humans received mRNA-based COVID-19 vaccines in March. The most common adverse events emerge right after a vaccination, Dr. Kuppalli said.
As with any vaccine that gains approval, monitoring will continue.
UK health officials have reported that two health care workers vaccinated in the initial rollout of the Pfizer vaccine had what seems to have been a severe allergic response. Both recipients had a history of anaphylactic allergic responses and carried EpiPens, and both recovered. During the trial, allergic reaction rates were 0.63% in the vaccine group and 0.51% in the placebo group.
As a result of the two reactions, UK regulators are now recommending that patients with a history of severe allergies not receive the vaccine at the current time.
Q: What are the likely side effects?
So far, the most common side effects are pain at the injection site and an achy, flu-like feeling, Dr. Kuppalli said. More severe reactions have been reported, but were not common in the trials.
Dr. Rasmussen noted that the common side effects are a good sign, and signal that the recipient is generating “a robust immune response.”
“Everybody I’ve talked to who’s had the response has said they would go through it again,” Dr. Kruppalli said. “I definitely plan on lining up and being one of the first people to get the vaccine.”
Q: I already had COVID-19 or had a positive antibody test. Do I still need to get the vaccine?
Dr. Rasmussen said that there are “too many unknowns” to say if a history of COVID-19 would make a difference. “We don’t know how long neutralizing antibodies last” after infection, she said. “What we know is that the vaccine tends to produce antibody titers towards the higher end of the spectrum,” suggesting better immunity with vaccination than after natural infection.
Q: Can patients of color feel safe getting the vaccine?
“People of color might be understandably reluctant to take a vaccine that was developed in a way that appears to be faster [than past development],” said Dr. Rasmussen. She said physicians should acknowledge and understand the history that has led them to feel that way, “everything from Tuskegee to Henrietta Lacks to today.”
Empathy is key, and “providers should meet patients where they are and not condescend to them.”
Dr. Kuppalli agreed. “Clinicians really need to work on trying to strip away their biases.”
Thus far there are no safety signals that differ by race or ethnicity, according to the companies. The Pfizer phase 3 trial enrolled just over 9% Black participants, 0.5% Native American/Alaska Native, 0.2% Native Hawaiian/Pacific Islander, 2.3% multiracial participants, and 28% Hispanic/Latinx. For its part, Moderna says that approximately 37% of participants in its phase 3 trial come from communities of color.
Q: What about children and pregnant women?
Although the trials included participants from many different age groups and backgrounds, children and pregnant or lactating women were not among them. Pfizer gained approval in October to include participants as young as age 12 years, and a Moderna spokesperson said in an interview that the company planned pediatric inclusion at the end of 2020, pending approval.
“Unfortunately, we don’t have data on pregnant and lactating women,” Dr. Kuppalli said. She said she hopes that public health organizations such as the CDC will address that in the coming weeks. Dr. Rasmussen called the lack of data in pregnant women and children “a big oversight.”
Dr. Rasmussen has disclosed no relevant financial relationships. Dr. Kuppalli is a consultant with GlaxoSmithKline.

Dr. Kuppalli agreed. “Clinicians really need to work on trying to strip away their biases.”
Thus far there are no safety signals that differ by race or ethnicity, according to the companies. The Pfizer phase 3 trial enrolled just over 9% Black participants, 0.5% Native American/Alaska Native, 0.2% Native Hawaiian/Pacific Islander, 2.3% multiracial participants, and 28% Hispanic/Latinx. For its part, Moderna says that approximately 37% of participants in its phase 3 trial come from communities of color.
Q: What about children and pregnant women?
Although the trials included participants from many different age groups and backgrounds, children and pregnant or lactating women were not among them. Pfizer gained approval in October to include participants as young as age 12 years, and a Moderna spokesperson said in an interview that the company planned pediatric inclusion at the end of 2020, pending approval.
“Unfortunately, we don’t have data on pregnant and lactating women,” Dr. Kuppalli said. She said she hopes that public health organizations such as the CDC will address that in the coming weeks. Dr. Rasmussen called the lack of data in pregnant women and children “a big oversight.”
Dr. Rasmussen has disclosed no relevant financial relationships. Dr. Kuppalli is a consultant with GlaxoSmithKline.

With U.S. approval of one coronavirus vaccine likely imminent and approval of a second one expected soon after, physicians will likely be deluged with questions. Public attitudes about the vaccines vary by demographics, with a recent poll showing that men and older adults are more likely to choose vaccination, and women and people of color evincing more wariness.
Although the reasons for reluctance may vary, questions from patient will likely be similar. Some are related to the “warp speed” language about the vaccines. Other concerns arise from the fact that the platform – mRNA – has not been used in human vaccines before. And as with any vaccine, there are rumors and false claims making the rounds on social media.
In anticipation of the most common questions physicians may encounter, two experts, Krutika Kuppalli, MD, assistant professor of medicine in the division of infectious diseases at the Medical University of South Carolina, Charleston, and Angela Rasmussen, PhD, virologist and nonresident affiliate at Georgetown University’s Center for Global Health Science and Security, Washington, talked in an interview about what clinicians can expect and what evidence-based – as well as compassionate – answers might look like.
Q: Will this vaccine give me COVID-19?
“There is not an intact virus in there,” Dr. Rasmussen said. The mRNA-based vaccines cannot cause COVID-19 because they don’t use any part of the coronavirus itself. Instead, the Moderna and Pfizer vaccines contain manufactured mRNA molecules that carry the instructions for building the virus’ spike protein. After vaccine administration, the recipient’s own cells take up this mRNA, use it to build this bit of protein, and display it on their surfaces. The foreign protein flag triggers the immune system response.
The mRNA does not enter the cell nucleus or interact with the recipient’s DNA. And because it’s so fragile, it degrades quite quickly. To keep that from happening before cell entry, the mRNAs are cushioned in protective fats.
Q: Was this vaccine made too quickly?
“People have been working on this platform for 30 years, so it’s not that this is brand new,” Dr. Kuppalli said.
Researchers began working on mRNA vaccines in the 1990s. Technological developments in the last decade have meant that their use has become feasible, and they have been tested in animals against many viral diseases. The mRNA vaccines are attractive because they’re expected to be safe and easily manufactured from common materials. That’s what we’ve seen in the COVID-19 pandemic, the Centers for Disease Control and Prevention says on its website. Design of the spike protein mRNA component began as soon as the viral genome became available in January.
Usually, rolling out a vaccine takes years, so less than a year under a program called Operation Warp Speed can seem like moving too fast, Dr. Rasmussen acknowledged. “The name has given people the impression that by going at warp speed, we’re cutting all the corners. [But] the reality is that Operation Warp Speed is mostly for manufacturing and distribution.”
What underlies the speed is a restructuring of the normal vaccine development process, Dr. Kuppalli said. The same phases of development – animal testing, a small initial human phase, a second for safety testing, a third large phase for efficacy – were all conducted as for any vaccine. But in this case, some phases were completed in parallel, rather than sequentially. This approach has proved so successful that there is already talk about making it the model for developing future vaccines.
Two other factors contributed to the speed, said Dr. Kuppalli and Dr. Rasmussen. First, gearing up production can slow a rollout, but with these vaccines, companies ramped up production even before anyone knew if the vaccines would work – the “warp speed” part. The second factor has been the large number of cases, making exposures more likely and thus accelerating the results of the efficacy trials. “There is so much COVID being transmitted everywhere in the United States that it did not take long to hit the threshold of events to read out phase 3,” Dr. Rasmussen said.
Q: This vaccine has never been used in humans. How do we know it’s safe?
The Pfizer phase 3 trial included more than 43,000 people, and Moderna’s had more than 30,000. The first humans received mRNA-based COVID-19 vaccines in March. The most common adverse events emerge right after a vaccination, Dr. Kuppalli said.
As with any vaccine that gains approval, monitoring will continue.
UK health officials have reported that two health care workers vaccinated in the initial rollout of the Pfizer vaccine had what seems to have been a severe allergic response. Both recipients had a history of anaphylactic allergic responses and carried EpiPens, and both recovered. During the trial, allergic reaction rates were 0.63% in the vaccine group and 0.51% in the placebo group.
As a result of the two reactions, UK regulators are now recommending that patients with a history of severe allergies not receive the vaccine at the current time.
Q: What are the likely side effects?
So far, the most common side effects are pain at the injection site and an achy, flu-like feeling, Dr. Kuppalli said. More severe reactions have been reported, but were not common in the trials.
Dr. Rasmussen noted that the common side effects are a good sign, and signal that the recipient is generating “a robust immune response.”
“Everybody I’ve talked to who’s had the response has said they would go through it again,” Dr. Kruppalli said. “I definitely plan on lining up and being one of the first people to get the vaccine.”
Q: I already had COVID-19 or had a positive antibody test. Do I still need to get the vaccine?
Dr. Rasmussen said that there are “too many unknowns” to say if a history of COVID-19 would make a difference. “We don’t know how long neutralizing antibodies last” after infection, she said. “What we know is that the vaccine tends to produce antibody titers towards the higher end of the spectrum,” suggesting better immunity with vaccination than after natural infection.
Q: Can patients of color feel safe getting the vaccine?
“People of color might be understandably reluctant to take a vaccine that was developed in a way that appears to be faster [than past development],” said Dr. Rasmussen. She said physicians should acknowledge and understand the history that has led them to feel that way, “everything from Tuskegee to Henrietta Lacks to today.”
Empathy is key, and “providers should meet patients where they are and not condescend to them.”
Dr. Kuppalli agreed. “Clinicians really need to work on trying to strip away their biases.”

Vitamin D deficiency in COVID-19 quadrupled death rate
Vitamin D deficiency on admission to hospital was associated with a 3.7-fold increase in the odds of dying from COVID-19, according to an observational study looking back at data from the first wave of the pandemic.
Nearly 60% of patients with COVID-19 were vitamin D deficient upon hospitalization, with men in the advanced stages of COVID-19 pneumonia showing the greatest deficit.
Importantly, the results were independent of comorbidities known to be affected by vitamin D deficiency, wrote the authors, led by Dieter De Smet, MD, from AZ Delta General Hospital, Roeselare, Belgium.
“[The findings] highlight the need for randomized, controlled trials specifically targeting vitamin D–deficient patients at intake, and make a call for general avoidance of vitamin D deficiency as a safe and inexpensive possible mitigation of the SARS-CoV-2 pandemic,” Dr. De Smet and colleagues wrote in their article, published online Nov. 25 in the American Journal of Clinical Pathology.
A search of ClinicalTrials.gov reveals there are currently close to 40 ongoing intervention trials with vitamin D in COVID-19 around the world for varying purposes, including prevention, and varying forms of treatment.
Consider vitamin D to prevent COVID-19 infection
With regard to the potential role in prevention, “Numerous observational studies have shown that low vitamin D levels are a major predictor for poor COVID outcomes,” noted Jacob Teitelbaum, MD, an internist who specializes in treating chronic fatigue syndrome and fibromyalgia who also has an interest in COVID-19.
“This study shows how severe a problem this is,” Dr. Teitelbaum said in an interview. “A 3.7-fold increase in death rate if someone’s vitamin D level was below 20 [ng/mL] is staggering. It is arguably one of the most important risk factors to consider.”
“What is not clear is whether vitamin D levels are acting as an acute-phase reactant, dropping because of the infection, with larger drops indicating more severe disease, or whether vitamin D deficiency is causing worse outcomes,” added Dr. Teitelbaum, who is director of the Center for Effective CFIDS/Fibromyalgia Therapies, Kailua-Kona, Hawaii.
Also asked to comment, Andrea Giustina, MD, president of the European Society of Endocrinology, said: “The paper by De Smet et al confirms what we already hypothesized in BMJ last March: that patients with low vitamin D levels are at high risk of hospitalization for COVID-19 and developing severe and lethal disease. This is likely due to the loss in the protective action of vitamin D on the immune system and against the SARS-CoV-2–induced cytokine storm.”
He said it is particularly interesting that the authors of the new study had reported more prevalent vitamin D deficiency among men than women, most likely because women are more often treated with vitamin D for osteoporosis.
The new study should prompt all clinicians and health authorities to seriously consider vitamin D supplementation as an additional tool in the fight against COVID-19, particularly for the prevention of infection in those at high risk of both COVID-19 and hypovitaminosis D, such the elderly, urged Dr. Giustina, of San Raffaele Vita-Salute University, Milan.
Results adjusted for multiple confounders
Dr. De Smet and colleagues looked at serum 25-hydroxyvitamin D (25[OH]D) levels in 186 patients hospitalized for severe COVID-19 infection as a function of radiologic stage of COVID-19 pneumonia as well as the association between vitamin D status on admission and COVID-19 mortality.
Cognizant of the potential for confounding by multiple factors, they adjusted for age, sex, and known vitamin D–affected comorbidities such as diabetes, chronic lung disease, and coronary artery disease.
Patients were hospitalized from March 1 to April 7, 2020 (the peak of the first wave of the pandemic) at their institution, AZ Delta General Hospital, a tertiary network hospital.
The mean age of patients was 69 years, 41% were women, and 59% had coronary artery disease. Upon admission to hospital, median vitamin D level was 18 ng/mL (women, 20.7 ng/mL; men, 17.6 ng/mL).
A remarkably high percentage (59%, 109/186) of patients with COVID-19 were vitamin D deficient (25[OH]D <20 ng/mL) when admitted (47% of women and 67% of men), wrote the authors.
“What surprises me,” said Dr. Teitelbaum, is that almost 60% “of these patients had 25(OH)D under 20 ng/mL but most clinicians consider under 50 to be low.”
All patients had a chest CT scan to determine the radiologic stage of COVID-19 pneumonia and serum vitamin D measurement on admission. Radiologic stage of pneumonia was used as a proxy for immunologic phase of COVID-19.
Vitamin D deficiency correlated with worsening pneumonia
Among men, rates of vitamin D deficiency increased with advancing disease, with rates of 55% in stage 1, 67% in stage 2, and up to 74% in stage 3 pneumonia.
There is therefore “a clear correlation between 25(OH)D level and temporal stages of viral pneumonia, particularly in male patients,” the authors wrote.
“Vitamin D dampens excessive inflammation,” said Dr. Teitelbaum. “In these patients with acute respiratory distress syndrome, the immune system has gone wild.”
“The study was carried out in Belgium, so there’s less sunlight there than some other places, but even here in Hawaii, with plenty of sunshine, we have vitamin D deficiency,” he added.
“More studies are needed, but I think there are enough data to suggest a multivitamin should be used to aid prophylaxis, and this is reflected in [some] infectious disease recommendations,” he noted.

Just under three million will get COVID-19 vaccine in first week
The federal government says it will distribute only enough doses of Pfizer’s COVID-19 vaccine to immunize 2.9 million Americans in the first week after the US Food and Drug Administration (FDA) authorizes it, far less than the initially discussed 6.4 million doses.
Theoretically, states have already formulated plans for distribution based on the revised lower amount. But in a briefing with reporters on December 9, officials from Operation Warp Speed and the Department of Health and Human Services (HHS) didn’t make clear exactly what the states were expecting.
Vaccine will be shipped to and allocated by 64 jurisdictions and five federal agencies — the Bureau of Prisons, the Department of Defense, the Department of State, the Indian Health Service, and the Veterans Health Administration — according to the Centers for Disease Control and Prevention’s COVID-19 Vaccination Program Interim Playbook.
It will be up to states — which will receive a supply prorated to population — and these agencies to determine how to prioritize distribution of the 2.9 million doses. Each state and agency has its own plan. Gen. Gustave Perna, the chief operating officer for Operation Warp Speed, said in the briefing that 30 states have told the federal government they will prioritize initial doses for residents and staff of long-term care facilities.
The distribution is contingent on FDA authorization, which could happen soon. The FDA’s Vaccines and Related Biologics Advisory Committee weighed the effectiveness data for the Pfizer vaccine on December 10 and recommended that the agency grant emergency authorization. The FDA could issue a decision at any time.
Fewer doses out of the gate
Perna said the federal government will begin shipping the Pfizer vaccine within 24 hours of an FDA authorization.
He said those shipments will include a total of 2.9 million doses — not the 6.4 million that will be available. The government is holding 500,000 doses in reserve and another 2.9 million to guarantee that the first few million people who are vaccinated will be able to receive a second dose 21 days later, said Perna.
In part, that is because the FDA labeling will require that a first dose be followed by a second exactly 21 days later, said HHS Secretary Alex Azar in the briefing.
Federal officials have calculated how much to hold back on the basis of Pfizer’s production, said Azar. At least initially, “we will not distribute a vaccine knowing that the booster will not be available either from reserve supply by us or ongoing expected predicted production,” he said.
Even with Pfizer having reduced its estimates of how much vaccine it can deliver in December, Azar said, “There will be enough vaccine available for 20 million first vaccinations in the month of December.”
That estimate is predicated, however, on the idea that a vaccine under development by Moderna will receive clearance shortly after the FDA assesses that vaccine’s safety and effectiveness on December 17.

FDA panel overwhelmingly backs emergency authorization for Pfizer COVID vaccine
Federal advisers on Thursday told US regulators that the benefits of Pfizer's COVID vaccine outweigh its risks for people aged 16 years and older, moving this product closer to a special emergency clearance.
The US Food and Drug Administration (FDA) put Pfizer's application before its Vaccines and Related Biological Products Advisory Committee (VRBPAC), seeking expert feedback on what is likely to be the first COVID-19 vaccine cleared for use in the United States.
New York-based Pfizer is seeking an emergency use authorization (EUA) for its vaccine, known as BNT162b2, which it developed with Germany's BioNTech. The FDA asked its advisers to vote on a single question regarding this product: "Based on the totality of scientific evidence available, do the benefits of the Pfizer-BioNTech COVID-19 Vaccine outweigh its risks for use in individuals 16 years of age and older?"
The members of VRBPAC voted 17-4 in favor of the Pfizer vaccine, with one panelist abstaining. The FDA considers the recommendations of its panels, but is not bound by them. The agency is expected to quickly grant the special clearance to Pfizer's vaccine, with the company then expected to complete work needed for a more complete biologics license application (BLA).
The FDA often allows members of its advisory committees to explain the reasons for their decisions to vote for or against an application after the tallies are publicly counted.
But the FDA did not give VRBPAC members this opportunity on Thursday, leaving the public without detailed insight into their support or objections.
Before the vote, several panelists had asked if the FDA could rephrase the voting question, raising the age for the approved group to perhaps 18 years of age. During the day, panelists also had questioned whether Pfizer's studies give enough information to judge whether the vaccine works against severe cases of COVID. And there was a discussion about how Pfizer could address concerns about the potential for allergic reactions to the vaccine, given the news of two healthcare workers who experienced allergic reactions after having the vaccine but who have since recovered.
In closing the meeting, VRBPAC chairman, Arnold Monto, MD, noted that the panel will on Dec. 17 meet again to offer recommendations on Moderna Inc.'s COVID vaccine.
"I believe most of us are going to be revisiting some of these issues in about a week," he said.
The panelist who abstained was H. Cody Meissner, MD, an expert in pediatric infectious disease from Tufts University. He earlier was among the several panelists who raised questions about the limited data available about the benefit to those ages 16 and 17. Those voting against the application were Michael Kurilla, MD, PhD; Archana Chatterjee, MD, PhD; A. Oveta Fuller, PhD, and David Kim, MD, MA, according to a tally read by the FDA staff after the vote.
Meanwhile, Sheldon Toubman, JD, voted in favor of the application according to the FDA staff's tally. Toubman had been a chief critic among VRBPAC members in reviewing Pfizer's application at the meeting. He'd suggested limiting the EUA to healthcare workers and residents of nursing homes. Members of these two groups are expected to be the first in the US to get Pfizer's vaccine, for which there will be only a limited initial supply. That idea gained no traction.
Toubman also pressed for more evidence that Pfizer's vaccine will work against severe cases of COVID.
The FDA staff on December 8 released a largely positive agency review of Pfizer vaccine. The efficacy of a two-dose administration of the vaccine has been pegged at 95.0%, with eight COVID-19 cases in the vaccine group and 162 COVID-19 cases in the placebo group. The FDA staff said that the 95% credible interval for the vaccine efficacy was 90.3% to 97.6%.
In that review, the FDA staff said there may be a hint from the results observed to date that the Pfizer vaccine may help ward off severe cases of COVID-19. There were 10 study participants that had severe COVID-19 disease after the first dose: one who received the vaccine and nine who received placebo.
"The total number of severe cases is small, which limits the overall conclusions that can be drawn; however, the case split does suggest protection from severe COVID-19 disease," the FDA staff said.
At the meeting today, Doron Fink, MD, PhD, a lead FDA official on the COVID vaccine review, responded directly to Toubman's concerns. There are many examples of vaccines that protect as well if not better against severe disease as they do against mild to moderate disease, Fink said.
"Protecting against disease of any severity is actually a pretty good predictor of protection against severe disease," Fink said, adding that there's already been a "strong result" shown in terms of the efficacy of Pfizer's vaccine.
Rolling out
Canadian health regulators on December 9 announced their nation's conditional approval of Pfizer's vaccine for people ages 16 and older. In the United Kingdom, a widely publicized rollout of Pfizer's vaccine began on Dec. 8. News quickly spread about two workers in the National Health Service having allergic reactions following vaccination. Both of these workers carry adrenaline autoinjectors, suggesting they have suffered reactions in the past, the Guardian reported. These kinds of autoinjectors are well known in the United States under the brand name EpiPen.
A noted vaccine expert serving on VRBPAC, Paul Offit, MD, of Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, urged the FDA and Pfizer to investigate any connection between reaction to the vaccine and known allergies. If not fully addressed, reports of the reactions seen in initial vaccinations in the UK could prove to unnecessarily frighten people who have allergies away from getting the COVID shot, he said.
Offit suggested running tests where people with egg and peanut allergies would get the Pfizer vaccine under close medical observation "to prove that this is not going to be a problem."
"This is a practical solution because this issue is not going to die until we have better data," Offit said.
More than a dozen COVID-19 vaccines have reached advanced stages of testing, including ones developed in Russia and China, according to the World Health Organization (WHO). The two leading candidates for the US market are the Pfizer/BioNTech vaccine and a similar vaccine developed by Moderna and the National Institute of Allergy and Infectious Diseases. Johnson & Johnson and AstraZeneca are among the other companies with COVID-19 vaccines in testing.
The rapid development of COVID vaccines will create challenges in testing these products. A key issue will be how and whether to continue with placebo-controlled trials, even though such research would be helpful, FDA advisers said.
The FDA tasked Steven Goodman, MD, MHS, PhD, of Stanford University with presenting an overview of considerations for continuing a placebo-controlled trial as COVID vaccines become available. Once a COVID-19 vaccine becomes available to the public, people who have received placebo in the Pfizer trial should not be allowed to immediately receive the vaccine, Goodman said.
There isn't a strong medically-based argument against placebo-controlled research in COVID-19, as many people can take steps to reduce their risk for the infection, Goodman said.
"So as long as there are still important things to learn about the vaccine, placebo-controlled trials should not be regarded as unethical," Goodman said. " I think, however, they might be infeasible. And that is a big issue, because people may not be willing to either remain in the study or to enroll."
During the public comment session, a former FDA official spoke of a need for careful consideration of study volunteers' needs in designing trials of COVID-19 vaccines.
"Reasonable people can disagree over whether study subjects should have priority access to a product whose efficacy they helped demonstrate," said Peter Lurie, MD, president of the nonprofit Center for Science in the Public Interest. "But we ought to be able to agree on this: No subject who has put their body on the line in a vaccine study should be at a disadvantage in terms of vaccine access as a result of their participation."
Lurie argued against extended periods of blinded follow-up after authorization of a COVID-19 vaccine. Such a requirement would be "hard to justify ethically, if it is inconsistent with public health recommendations, particularly with rapidly rising case rates and the reported levels of effectiveness" of the Pfizer vaccine, said Lurie, who served as an associate commissioner at FDA from 2014 to 2017.
Lurie also noted the FDA staff's identification of what he called "disproportionate numbers of Bell's Palsy cases (4 in the vaccine groups vs. 0 in the placebo group)" as a matter that should continue to be monitored, including in the postmarketing phase. He raised no objections to the EUA.
Sidney Wolfe, MD, founder and senior adviser to Public Citizen's Health Research Group, also spoke at the public comment session, citing no objection to an EUA for the Pfizer vaccine. Like Lurie, he urged special consideration of people who have or will receive placebo in COVID-19 vaccine trials.
The Thursday advisory committee on the Pfizer vaccine differed from those held for many other products. The discussion focused more on how to monitor and evaluate the vaccine once approved, while advisory committees sometimes include a detailed look at whether a company has proven that its product works. One of the special advisers serving temporarily on VRBPAC, Eric J. Rubin, MD, PhD, also today published an editorial in The New England Journal of Medicine, titled "SARS-CoV-2 Vaccination — An Ounce (Actually, Much Less) of Prevention."
In the editorial, Rubin and coauthor, Dan L. Longo, MD, called the Pfizer vaccine results seen so far "impressive."
"In the primary analysis, only 8 cases of Covid-19 were seen in the vaccine group, as compared with 162 in the placebo group, for an overall efficacy of 95% (with a 95% credible interval of 90.3 to 97.6%)," they write. "Although the trial does not have the statistical power to assess subgroups, efficacy appeared to be similar in low-risk and high-risk persons, including some from communities that have been disproportionately affected by disease, and in participants older than 55 years of age and those younger than 55."
Intense Scrutiny
The FDA has come under intense scrutiny this year in part because of the aggressive — and ultimately unrealistic — timelines for COVID-19 treatments promoted by the Trump administration. President Donald Trump several times suggested a COVID-19 vaccine could be approved before the November election. Many concerned physicians and scientists including Medscape Editor-in-Chief Eric Topol, MD, called on FDA staff to fight back against any bid to inappropriately speed the approval process for political reasons.
"Any shortcuts will not only jeopardize the vaccine programs but betray the public trust, which is already fragile about vaccines, and has been made more so by your lack of autonomy from the Trump administration and its overt politicization of the FDA," Topol wrote in an August open letter to FDA Commissioner Stephen Hahn, MD.
In an October interview with Topol, Hahn noted that there has been some pushback against the idea of an EUA for a COVID-19 vaccine, with some people preferring to wait for a more complete biological license application.
"When you're talking about a pandemic where people are dying, you want to expedite it as much as possible," Hahn told Topol in the interview.
On Thursday, Hahn issued a public statement about the VRBPAC meeting. Hahn said the FDA's "career staff — made up of physicians, biologists, chemists, epidemiologists, statisticians, and other professionals — have been working around the clock to thoroughly evaluate the data and information in the EUA request."
"I can assure you that no vaccine will be authorized for use in the United States until FDA career officials feel confident in allowing their own families to receive it," Hahn said.
Many clinicians offered their views on the FDA meeting during the day on Twitter.
Robert Wachter, MD, chair of the Department of Medicine at the University of California, San Francisco, who has been a vocal opponent of some of Trump's public statements on COVID-19, urged state officials to stick with the FDA's call on the Pfizer vaccine. In a tweet, he noted that officials in California and several other states have called for independent reviews of COVID-19 vaccines.
If such reviews were to delay distribution of vaccines, this would "lead to more harm than good," Wachter tweeted. "Once FDA says 'go', we should go."

On Thursday, Hahn issued a public statement about the VRBPAC meeting. Hahn said the FDA's "career staff — made up of physicians, biologists, chemists, epidemiologists, statisticians, and other professionals — have been working around the clock to thoroughly evaluate the data and information in the EUA request."
"I can assure you that no vaccine will be authorized for use in the United States until FDA career officials feel confident in allowing their own families to receive it," Hahn said.
Many clinicians offered their views on the FDA meeting during the day on Twitter.
Robert Wachter, MD, chair of the Department of Medicine at the University of California, San Francisco, who has been a vocal opponent of some of Trump's public statements on COVID-19, urged state officials to stick with the FDA's call on the Pfizer vaccine. In a tweet, he noted that officials in California and several other states have called for independent reviews of COVID-19 vaccines.
If such reviews were to delay distribution of vaccines, this would "lead to more harm than good," Wachter tweeted. "Once FDA says 'go', we should go."

Patients with lung and blood cancers most vulnerable to COVID-19
Patients with cancer are at significantly increased risk for COVID-19 and worse outcomes, a new review confirms. It also found that patients with leukemia, non-Hodgkin lymphoma, and lung cancer are at greatest risk.
Blacks with cancer are at even higher risk, and for patients with colorectal cancer and non-Hodgkin lymphoma, the risk is higher for women than for men. (This contrasts with findings in noncancer populations, where men are more at risk from COVID-19 and severe outcomes than women.)
These findings come from a huge review of electronic health records of 73.4 million patients in the United States. They “highlight the need to protect and monitor patients with cancer as part of the strategy to control the pandemic,” the authors wrote.
The review was published online Dec. 10 in JAMA Oncology.
The greater risk for COVID-19 among patients with cancer is well known, but breaking the risk down by cancer type is novel, wrote the investigators, led by Quanqiu Wang, MS, Center for Artificial Intelligence in Drug Discovery, Case Western Reserve University, Cleveland.
Cancer patients are immunocompromised and have more contact with the health care system, which increases their risk for COVID-19. But which bodily systems are affected by cancer seems to matter. In patients with blood cancer, for example, COVID-19 is probably more dangerous, because blood cancer weakens the immune system directly, the authors suggested.
The increased risk for infection and hospitalization with SARS-CoV-2 among Black patients with cancer might be because of biology, but it is more likely because of factors that weren’t captured in the database review. Such factors include social adversity, economic status, access to health care, and lifestyle, the researchers noted.
For this study, the investigators analyzed electronic health records held in the IBM Watson Health Explorys system, which captures about 15% of new cancer diagnoses in the United States.
The analysis found that, as of Aug. 14, 2020, 16,570 patients (0.02%) had been diagnosed with COVID-19; about 1,200 also had been diagnosed with cancer. Of those, 690 were diagnosed with cancer in the previous year, which counted as a recent cancer diagnosis in the analysis. The study included 13 common cancers, including endometrial, kidney, liver, lung, gastrointestinal, prostate, skin, and thyroid cancers, among others.
Patients with any cancer diagnosis (adjusted odds ratio, 1.46) as well as those with a recent cancer diagnosis (aOR, 7.14) had a significantly higher risk for COVID-19 than those without cancer, after adjusting for asthma, cardiovascular diseases, nursing home stays, and other risk factors.
The risk for COVID-19 was highest among patients recently diagnosed with leukemia (aOR, 12.16), non-Hodgkin lymphoma (aOR, 8.54), and lung cancer (aOR 7.66). The risk for COVID-19 was lower for patients with cancers associated with worse prognoses, including pancreatic (aOR, 6.26) and liver (aOR, 6.49) cancer. It was weakest for patients with thyroid cancer (aOR, 3.10; P for all < .001).
Hospitalization was more common in recent cancer patients with COVID-19 than in COVID-19 patients without cancer (47.46% vs. 24.6%), as was COVID-19–related death (14.93% vs. 5.26%). Among cancer patients who did not have COVID-19, 12.39% were hospitalized, and 4.03% died. The findings suggest a synergistic effect between the COVID-19 and cancer, the team noted.
Among patients recently diagnosed with cancer, Black patients – 10.3% of the overall study population – had a significantly higher risk for COVID-19 than White patients. The racial disparity was largest for patients with breast cancer (aOR, 5.44), followed by patients with prostate cancer (aOR, 5.10), colorectal cancer (aOR, 3.30), and lung cancer (aOR, 2.53; P for all < .001).
Hospitalizations were more common among Black patients with cancer and COVID-19 than White patients. There was also a trend toward higher mortality among Black patients (18.52% vs. 13.51%; P = .11)
However, these differences may not be related to race, oncologist Aakash Desai, MBBS, of the Mayo Clinic, Rochester, Minn., and colleagues noted in an accompanying commentary. “Interestingly, a previous study of hospitalized patients with COVID-19 without cancer demonstrated that mortality rates for Black patients were comparable to those for White patients after adjustment for both comorbidities and deprivation index, suggesting that observed differences are mainly owing to societal disparities rather than biology.”
The editorialists also noted that the finding that Black patients with cancer are at greater risk for COVID-19 (aOR, 1.58-5.44, depending on cancer) echoes the findings in the general population. The Centers for Disease Control and Prevention estimates a severalfold increased risk among Black patients. These higher rates may largely be explained by social determinants, they suggested. Such factors include increased burden of comorbidities, crowded living conditions (inner cities, multigenerational homes, etc.), dependence on public transportation or child care, and higher work-related exposures. “Until such societal disparities are accounted for, we cannot presume these findings are caused by any inherent differences among racial groups,” the editorialists wrote.
“Clearly, the haunting spotlight of COVID-19 has dramatically illuminated known U.S. health care and societal disparities,” Dr. Desai and colleagues wrote. “This situation should be a wake-up call that brings much-needed improvements in U.S. equity policies, including but not limited to better health care access. Nothing appears more critical for alleviating these disparate clinical outcomes in this time of crisis and beyond,” they declared.
The study was funded by the National Institutes of Health, the American Cancer Society, and other organizations. The investigators disclosed having no relevant financial relationships.

Pfizer can’t supply additional vaccines to U.S. until June
Pfizer won’t be able to provide more COVID-19 vaccine doses to the United States until late June or July because other countries have bought up the available supply, according to The Washington Post.
The U.S. government signed a deal with the giant pharmaceutical company earlier this year to provide 100 million doses for $1.95 billion – enough for 50 million Americans to receive the two-dose vaccine. At that time, Pfizer officials encouraged Operation Warp Speed officials to purchase an additional 100 million doses, The New York Times first reported Dec. 7, but the federal officials declined.
Since then, other countries have signed vaccine deals with Pfizer, so the U.S. may not be able to receive a second major allotment until the summer of 2021, The Washington Post reported. Without a substantial number of additional doses, the U.S. may not be able to follow its schedule of vaccinating the majority of Americans against COVID-19 by April or May.
However, Trump administration officials told the newspaper that there won’t be issues, citing other vaccine companies such as Moderna.
“I’m not concerned about our ability to buy vaccines to offer to all of the American public,” Gen. Paul Ostrowski, who oversees logistics for Operation Warp Speed, told The Washington Post.
“It’s clear that Pfizer made plans with other countries. Many have been announced. We understand those pieces,” he said.
With Pfizer’s COVID-19 vaccine on the verge of FDA approval, federal officials contacted the company last weekend to buy another 100 million doses, but the company said its current supply is already committed, the newspaper reported.
The vaccine from Pfizer and BioNTech is expected to win emergency approval within days and has been shown to be effective against COVID-19.
Pfizer added that it may be able to provide 50 million doses at the end of the second quarter and another 50 million doses during the third quarter. However, the company can’t offer anything “substantial” until next summer.
Beyond the initial 100 million doses that the U.S. has already secured, Pfizer and federal officials would need to negotiate a new, “separate and mutually acceptable agreement,” Amy Rose, a spokeswoman for Pfizer, told the newspaper.
On Dec. 8, President Donald Trump was expected to sign an executive order prioritizing vaccination for Americans first before providing doses to other countries, according to Fox News.
The order will provide guidelines to the Department of Health and Human Services, the U.S. Agency for International Development and the U.S. International Development Finance Corporation for foreign assistance with vaccines, the news outlet reported.
It’s unclear whether the executive order is related to the Pfizer issue, whether the president can prevent a private company from fulfilling contracts with other countries, and whether President-elect Joe Biden will create his own policy, according to CNBC. The order may prove to be mostly symbolic.
The FDA could issue an emergency use authorization for Pfizer’s coronavirus vaccine this week and will likely approve Moderna’s vaccine next week. The U.S. has signed a contract with Moderna for 100 million doses.
During a call with reporters on Dec. 7, a spokeswoman for the Department of Health and Human Services said, “We are confident that we will have 100 million doses of Pfizer’s vaccine as agreed to in our contract, and beyond that, we have five other vaccine candidates, including 100 million doses on the way from Moderna.”
Federal officials are counting on vaccine candidates from AstraZeneca and Johnson & Johnson to seek FDA approval in January and be ready for shipment in February.
“We could have all of them,” Moncef Slaoui, the chief science adviser for Operation Warp Speed, told The Washington Post on Dec. 7.
“And for this reason, we feel confident we could cover the needs without a specific cliff,” he said. “We have planned things in such a way as we would indeed avoid a cliff.”

Can a health care worker refuse the COVID-19 vaccine?
As hospitals across the country develop their plans to vaccinate their health care employees against COVID-19, a key question has come to the fore: What if an employee – whether nurse, physician, or other health care worker – refuses to receive the vaccine? Can hospitals require their employees to be vaccinated against COVID-19? And what consequences could an employee face for refusing the vaccine?
My answer needs to be based, in part, on the law related to previous vaccines – influenza, for example – because at the time of this writing (early December 2020), no vaccine for COVID-19 has been approved, although approval of at least one vaccine is expected within a week. So there have been no offers of vaccine and refusals yet, nor are there any cases to date involving an employee who refused a COVID-19 vaccine. As of December 2020, there are no state or federal laws that either require an employee to be vaccinated against COVID-19 or that protect an employee who refuses vaccination against COVID-19. It will take a while after the vaccine is approved and distributed before refusals, reactions, policies, cases, and laws begin to emerge.
If we look at the law related to health care workers refusing to be vaccinated against the closest relative to COVID-19 – influenza – then the answer would be yes, employers can require employees to be vaccinated.
An employer can fire an employee who refuses influenza vaccination. If an employee who refused and was fired sues the employer for wrongful termination, the employee has more or less chance of success depending on the reason for refusal. Some courts and the Equal Employment Opportunity Commission have held that a refusal on religious grounds is protected by the U.S. Constitution, as in this recent case. The Constitution protects freedom to practice one’s religion. Specific religions may have a range of tenets that support refusal to be vaccinated.
A refusal on medical grounds has been successful if the medical grounds fall under the protections of the Americans with Disabilities Act but may fail when the medical grounds for the claim are not covered by the ADA.
Refusal for secular, nonmedical reasons, such as a health care worker’s policy of treating their body as their temple, has not gone over well with employers or courts. However, in at least one case, a nurse who refused vaccination on secular, nonmedical grounds won her case against her employer, on appeal. The appeals court found that the hospital violated her First Amendment rights.
Employees who refuse vaccination for religious or medical reasons still will need to take measures to protect patients and other employees from infection. An employer such as a hospital can, rather than fire the employee, offer the employee an accommodation, such as requiring that the employee wear a mask or quarantine. There are no cases that have upheld an employee’s right to refuse to wear a mask or quarantine.
The situation with the COVID-19 vaccine is different from the situation surrounding influenza vaccines. There are plenty of data on effectiveness and side effects of influenza vaccines, but there is very little evidence of short- or long-term effects of the COVID-19 vaccines currently being tested and/or considered for approval. One could argue that the process of vaccine development is the same for all virus vaccines. However, public confidence in the vaccine vetting process is not what it once was. It has been widely publicized that the COVID-19 vaccine trials have been rushed. As of December 2020, only 60% of the general population say they would take the vaccine, although researchers say confidence is increasing.
The Centers for Disease Control and Prevention has designated health care workers as first in line to get the vaccine, but some health care workers may not want to be the first to try it. A CDC survey found that 63% of health care workers polled in recent months said they would get a COVID-19 vaccine.
Unions have entered the conversation. A coalition of unions that represent health care workers said, “we need a transparent, evidence-based federal vaccine strategy based on principles of equity, safety, and priority, as well as robust efforts to address a high degree of skepticism about safety of an authorized vaccine.” The organization declined to promote a vaccine until more is known.
As of publication date, the EEOC guidance for employers responding to COVID-19 does not address vaccines.
The CDC’s Interim Guidance for Businesses and Employers Responding to Coronavirus Disease 2019, May 2020, updated Dec. 4, 2020, does not address vaccines. The CDC’s page on COVID-19 vaccination for health care workers does not address a health care worker’s refusal. The site does assure health care workers that the vaccine development process is sound: “The current vaccine safety system is strong and robust, with the capacity to effectively monitor COVID-19 vaccine safety. Existing data systems have validated analytic methods that can rapidly detect statistical signals for possible vaccine safety problems. These systems are being scaled up to fully meet the needs of the nation. Additional systems and data sources are also being developed to further enhance safety monitoring capabilities. CDC is committed to ensuring that COVID-19 vaccines are safe.”
In the coming months, government officials and vaccine manufacturers will be working to reassure the public of the safety of the vaccine and the rigor of the vaccine development process. In November 2020, National Institute of Allergy and Infectious Diseases Director Anthony Fauci, MD, told Kaiser Health News: “The company looks at the data. I look at the data. Then the company puts the data to the FDA. The FDA will make the decision to do an emergency-use authorization or a license application approval. And they have career scientists who are really independent. They’re not beholden to anybody. Then there’s another independent group, the Vaccines and Related Biological Products Advisory Committee. The FDA commissioner has vowed publicly that he will go according to the opinion of the career scientists and the advisory board.” President-elect Joe Biden said he would get a vaccine when Dr. Fauci thinks it is safe.
An employee who, after researching the vaccine and the process, still wants to refuse when offered the vaccine is not likely to be fired for that reason right away, as long as the employee takes other precautions, such as wearing a mask. If the employer does fire the employee and the employee sues the employer, it is impossible to predict how a court would decide the case.
Related legal questions may arise in the coming months. For example:
- Is an employer exempt from paying workers’ compensation to an employee who refuses to be vaccinated and then contracts the virus while on the job?
- Can a prospective employer require COVID-19 vaccination as a precondition of employment?
- Is it within a patient’s rights to receive an answer to the question: Has my health care worker been vaccinated against COVID-19?
- If a hospital allows employees to refuse vaccination and keep working, and an outbreak occurs, and it is suggested through contact tracing that unvaccinated workers infected patients, will a court hold the hospital liable for patients’ damages?
Answers to these questions are yet to be determined.

As hospitals across the country develop their plans to vaccinate their health care employees against COVID-19, a key question has come to the fore: What if an employee – whether nurse, physician, or other health care worker – refuses to receive the vaccine? Can hospitals require their employees to be vaccinated against COVID-19? And what consequences could an employee face for refusing the vaccine?
My answer needs to be based, in part, on the law related to previous vaccines – influenza, for example – because at the time of this writing (early December 2020), no vaccine for COVID-19 has been approved, although approval of at least one vaccine is expected within a week. So there have been no offers of vaccine and refusals yet, nor are there any cases to date involving an employee who refused a COVID-19 vaccine. As of December 2020, there are no state or federal laws that either require an employee to be vaccinated against COVID-19 or that protect an employee who refuses vaccination against COVID-19. It will take a while after the vaccine is approved and distributed before refusals, reactions, policies, cases, and laws begin to emerge.
If we look at the law related to health care workers refusing to be vaccinated against the closest relative to COVID-19 – influenza – then the answer would be yes, employers can require employees to be vaccinated.
An employer can fire an employee who refuses influenza vaccination. If an employee who refused and was fired sues the employer for wrongful termination, the employee has more or less chance of success depending on the reason for refusal. Some courts and the Equal Employment Opportunity Commission have held that a refusal on religious grounds is protected by the U.S. Constitution, as in this recent case. The Constitution protects freedom to practice one’s religion. Specific religions may have a range of tenets that support refusal to be vaccinated.
A refusal on medical grounds has been successful if the medical grounds fall under the protections of the Americans with Disabilities Act but may fail when the medical grounds for the claim are not covered by the ADA.
Refusal for secular, nonmedical reasons, such as a health care worker’s policy of treating their body as their temple, has not gone over well with employers or courts. However, in at least one case, a nurse who refused vaccination on secular, nonmedical grounds won her case against her employer, on appeal. The appeals court found that the hospital violated her First Amendment rights.
Employees who refuse vaccination for religious or medical reasons still will need to take measures to protect patients and other employees from infection. An employer such as a hospital can, rather than fire the employee, offer the employee an accommodation, such as requiring that the employee wear a mask or quarantine. There are no cases that have upheld an employee’s right to refuse to wear a mask or quarantine.
The situation with the COVID-19 vaccine is different from the situation surrounding influenza vaccines. There are plenty of data on effectiveness and side effects of influenza vaccines, but there is very little evidence of short- or long-term effects of the COVID-19 vaccines currently being tested and/or considered for approval. One could argue that the process of vaccine development is the same for all virus vaccines. However, public confidence in the vaccine vetting process is not what it once was. It has been widely publicized that the COVID-19 vaccine trials have been rushed. As of December 2020, only 60% of the general population say they would take the vaccine, although researchers say confidence is increasing.
The Centers for Disease Control and Prevention has designated health care workers as first in line to get the vaccine, but some health care workers may not want to be the first to try it. A CDC survey found that 63% of health care workers polled in recent months said they would get a COVID-19 vaccine.
Unions have entered the conversation. A coalition of unions that represent health care workers said, “we need a transparent, evidence-based federal vaccine strategy based on principles of equity, safety, and priority, as well as robust efforts to address a high degree of skepticism about safety of an authorized vaccine.” The organization declined to promote a vaccine until more is known.

Rechallenge ‘reasonable’ for some with small-cell lung cancer
In a phase 3 trial, carboplatin plus etoposide significantly prolonged progression-free survival (PFS), when compared with topotecan, in patients with advanced or relapsed, sensitive SCLC.
All patients had responded to first-line platinum plus etoposide, but they experienced relapse or progression 90 days or more after completing that treatment, according to study author Nathalie Baize, MD, of Angers University Hospital in France, and colleagues.
For this trial, Dr. Baize and colleagues enrolled 164 patients with advanced or relapsed SCLC. The median age of the 162 evaluable patients was 64 years, about two-thirds were men, and about 60% had an Eastern Cooperative Oncology Group performance status of 1.
The patients were randomized 1:1 to intravenous carboplatin (area under the curve 5 mg/mL per min on day 1) plus intravenous etoposide (100 mg/m² from day 1 to day 3) or to oral topotecan (2.3 mg/m² from day 1 to day 5 for six cycles). Primary prophylactic filgrastim was recommended for all patients in both treatment groups.
Results: Survival and adverse events
The median follow-up was 22.7 months. The median PFS was significantly longer in the combination therapy arm, at 4.7 months versus 2.7 months in the topotecan arm (stratified hazard ratio 0.57, P = .0041).
The median overall survival was similar in both arms, at 7.5 months in the carboplatin-etoposide arm and 7.4 months in the topotecan arm.
Patients in the carboplatin-etoposide arm had a significantly higher objective response rate, at 49% versus 25% in the topotecan arm (P = .0024).
The most common grade 3-4 adverse events (in the topotecan and combination arms, respectively) were neutropenia (22% vs. 14%), thrombocytopenia (36% vs. 31%), and anemia (21% vs. 25%).
Serious adverse events with hospitalization were reported in 37% of patients in the carboplatin-etoposide arm 43% in the topotecan arm. Febrile neutropenia with sepsis led to two treatment-related deaths in the topotecan group but none in the carboplatin-etoposide group.
Reasonable option for some
Based on the results of this trial, Dr. Baize and colleagues concluded that carboplatin-etoposide rechallenge “can be considered a reasonable second-line chemotherapy option for patients with sensitive relapsed small-cell lung cancer.”
However, while this trial was enrolling patients, immunotherapy and chemotherapy combinations became the standard of care in SCLC, Oscar Arrieta, MD, of Instituto Nacional de Cancerología in Mexico City, and colleagues noted in a related editorial.
Therefore, “reasonable doubts emerge regarding the application of this strategy in patients receiving immunotherapy,” Dr. Arrieta and colleagues wrote.
The editorialists urged conduct of a randomized trial to evaluate rechallenge with carboplatin plus etoposide versus lurbinectedin, which was approved earlier this year by the Food and Drug Administration for the treatment of sensitive and resistant relapsed SCLC.
Commenting on the choice between a platinum-etoposide combination and lurbinectedin, Sarah Goldberg, MD, of Yale University, New Haven, Conn., noted that she and her colleagues have been using the chemotherapy combination for several years.
“This trial confirms that practice and that it’s still a reasonable option for some patients,” Dr. Goldberg said in an interview.
For patients who had a very good first-line response to platinum-etoposide, longer than 180 days (even longer than the 90-day standard in the current trial), she said, “it seems like a rechallenge with platinum-etoposide would potentially be even more effective, and I’d save lurbinectedin for a later line.
“With refractory disease, less than 90 days, I would consider lurbinectedin,” Dr. Goldberg said.
This study was funded by Amgen and the French Lung Cancer Group (Groupe Français de Pneumo-Cancérologie). The researchers disclosed relationships with Pfizer, Roche, AbbVie, and many other companies. Dr. Arrieta disclosed relationships with AstraZeneca, Boehringer Ingelheim, Roche, Lilly, Merck, Pfizer, and Bristol-Myers Squibb. The other editorialists declared no competing interests. Dr. Goldberg disclosed relationships with AstraZeneca, Boehringer Ingelheim, Eli Lilly, Bristol-Myers Squibb, Genentech, Amgen, Spectrum, Blueprint Medicine, Sanofi Genzyme, Daiichi Sankyo, and Regeneron.

Fracking sites tied to increased heart failure hospitalizations
Living near hydraulic fracturing is associated with increased risk of hospitalization in people with heart failure (HF), a new study from Pennsylvania suggests.
The link was strongest among those with more severe heart failure but patients with either HF phenotype showed this association of increased risk with exposure to fracking activities, according to the investigators, led by Tara P. McAlexander, PhD, MPH, Drexel University Dornsife School of Public Health in Philadelphia.
“Our understanding has expanded well beyond the famous Harvard Six Cities study to know that it’s not just a short-term uptick in air pollution that›s going to send someone to the hospital a couple days later,” said Dr. McAlexander in an interview, referring to the study conducted from the mid-1970s through 1991. “We know that people who live in these environments and are exposed for long periods of time may have long-term detrimental effects.”
Although questions remain about specific mechanisms and how best to assess exposure, the evidence is mounting in a way that is consistent with the biologic hypotheses of how fracking would adversely affect health, Dr. McAlexander said. “We have many studies now on adverse pregnancy and birth outcomes, and that’s just the tip of the iceberg.”
Pennsylvania is a hot spot for fracking, also known as unconventional natural gas development (UNGD), with more than 12,000 wells drilled in the Marcellus shale since 2004. The shale extends from upstate New York in the north to northeastern Kentucky and Tennessee in the south and covers about 72,000 square miles. Last year, Pennsylvania pledged $3 million to study clusters of rare pediatric cancers and asthma near fracking operations. A recent grand jury report concluded government officials failed to protect residents from the health effects of fracking.
Fracking involves a cascade of activities that can trigger neural circuitry, sympathetic activation, and inflammation – all well-known pathways that potentiate heart failure, said Sanjay Rajagopalan, MD, who has researched the health effects of air pollution for two decades and was not involved with the study.
“If you think about it, it’s like environmental perturbation on steroids in some ways where they are pulling the trigger from a variety of different ways: noise, air pollution, social displacement, psychosocial impacts, economic disparities. So it’s not at all surprising that they saw an association,” said Dr. Rajagopalan, chief of cardiovascular medicine at University Hospitals Harrington Heart & Vascular Institute and director of the Case Western Cardiovascular Research Institute, both in Cleveland, Ohio.
As reported in the Journal of the American College of Cardiology, Dr. McAlexander and colleagues at Johns Hopkins University, Baltimore, used electronic health data from the Geisinger Health System to identify 9,054 patients with heart failure seen between 2008 and 2015. Of these, 5,839 patients had an incident HF hospitalization and 3,215 served as controls. Geisinger operates 13 hospitals and two research centers in 45 of Pennsylvania’s 67 counties, serving more than 3 million of the state’s residents.
Patients’ residential addresses were used to identify latitude and longitude coordinates that were matched with 9,669 UNGD wells in Pennsylvania and the location of major and minor roadways. The researchers also calculated a measure of community socioeconomic deprivation.
The adjusted odds of hospitalization were higher for patients in the highest quartile of exposure for three of the four UNGD phases: pad preparation (odds ratio, 1.70; 95% confidence interval, 1.35-2.13), stimulation or the actual fracking (OR, 1.80; 95% CI, 1.35-2.40), and production (OR, 1.62; 95% CI, 1.07-2.45).
Dr. McAlexander said she initially thought the lack of association with drilling (OR, 0.97; 95% CI, 0.75-1.27) was a mistake but noted that the drilling metric reflects a shorter time period than, for example, 30 days needed to clear the well pad and bring in the necessary equipment.
Stronger associations between pad preparation, fracking, and production are also consistent with the known increases in air pollution, traffic, and noise associated with these phases.
Individuals with more severe HF had greater odds of hospitalization, but the effect sizes were generally comparable between HF with preserved versus reduced ejection fraction. For those with the highest exposure to fracking, the odds ratios for hospitalization reached 2.25 (95% CI, 1.56-3.25) and 2.09 (95% CI, 1.44-3.03), respectively.
Notably, patients who could be phenotyped versus those who could not were more likely to die, to be hospitalized for HF, and to have a higher Charlson Comorbidity Index and other relevant diagnoses like myocardial infarction.
“Clinicians need to be increasingly aware that the environments their patients are in are a huge factor in their disease progression and outlook,” McAlexander said. “We know that UNGD, specifically now, is something that could be impacting a heart failure patient’s survival.”
She also suggested that the findings may also spur more advocacy work and “across-silo” collaboration between clinicians and environmental researchers.
Dr. Rajagopalan said there is increasing recognition that physicians need to be aware of environmental health links as extreme events like the California and Oregon wildfires and coastal flooding become increasingly common. “Unfortunately, unconventional is becoming the new convention.”
The problem for many physicians, however, is just having enough bandwidth to get through the day and get enough learning to keep above water, he said. Artificial intelligence could be used to seed electronic medical records with other personalized information from a bevy of sources including smartphones and the internet of things, but fundamental changes are also needed in the educational process to emphasize the environment.
“It’s going to take a huge societal shift in the way we view commodities, what we consider healthy, etc, but it can happen very quickly because all it takes is a crisis like COVID-19 to bring people to their knees and make them understand how this is going to take over our lives over the next decade,” Dr. Rajagopalan said.
The scientific community has been calling for “good” epidemiologic studies on the health effects of fracking since the early 2010s, Barrak Alahmad, MBChB, MPH, Harvard T.H. Chan School of Public Health, and Haitham Khraishah, MD, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, point out in an accompanying editorial.
The current study applied “extensive and rigorous methods” involving both the design and statistical approach, including use of a negative control analysis to assess for sources of spurious causal inference, several sensitivity analyses, and controlled for a wide range of covariates.
“Their results were consistent and robust across all these measures,” the editorialists wrote. “Most importantly, the effect size is probably too large to be explained away by an unmeasured confounder.”
Dr. Alahmad and Dr. Khraishah call for advancements in exposure assessment, citing a recent study reporting that ambient particle radioactivity near unconventional oil and gas sites could induce adverse health effects. Other unmet needs include a better understanding of racial disparities in the impacts of fracking and a fine-tuning of cause-specific cardiovascular morbidity and mortality.
The study was supported by training grants from the National Institute of Environmental Health Sciences to Dr. McAlexander and principal investigator Brian Schwartz, MD. The authors, Dr. Rajagopalan, Dr. Alahmad, and Dr. Khraishah have disclosed no relevant financial relationships.

Living near hydraulic fracturing is associated with increased risk of hospitalization in people with heart failure (HF), a new study from Pennsylvania suggests.
The link was strongest among those with more severe heart failure but patients with either HF phenotype showed this association of increased risk with exposure to fracking activities, according to the investigators, led by Tara P. McAlexander, PhD, MPH, Drexel University Dornsife School of Public Health in Philadelphia.
“Our understanding has expanded well beyond the famous Harvard Six Cities study to know that it’s not just a short-term uptick in air pollution that›s going to send someone to the hospital a couple days later,” said Dr. McAlexander in an interview, referring to the study conducted from the mid-1970s through 1991. “We know that people who live in these environments and are exposed for long periods of time may have long-term detrimental effects.”
Although questions remain about specific mechanisms and how best to assess exposure, the evidence is mounting in a way that is consistent with the biologic hypotheses of how fracking would adversely affect health, Dr. McAlexander said. “We have many studies now on adverse pregnancy and birth outcomes, and that’s just the tip of the iceberg.”
Pennsylvania is a hot spot for fracking, also known as unconventional natural gas development (UNGD), with more than 12,000 wells drilled in the Marcellus shale since 2004. The shale extends from upstate New York in the north to northeastern Kentucky and Tennessee in the south and covers about 72,000 square miles. Last year, Pennsylvania pledged $3 million to study clusters of rare pediatric cancers and asthma near fracking operations. A recent grand jury report concluded government officials failed to protect residents from the health effects of fracking.
Fracking involves a cascade of activities that can trigger neural circuitry, sympathetic activation, and inflammation – all well-known pathways that potentiate heart failure, said Sanjay Rajagopalan, MD, who has researched the health effects of air pollution for two decades and was not involved with the study.
“If you think about it, it’s like environmental perturbation on steroids in some ways where they are pulling the trigger from a variety of different ways: noise, air pollution, social displacement, psychosocial impacts, economic disparities. So it’s not at all surprising that they saw an association,” said Dr. Rajagopalan, chief of cardiovascular medicine at University Hospitals Harrington Heart & Vascular Institute and director of the Case Western Cardiovascular Research Institute, both in Cleveland, Ohio.
As reported in the Journal of the American College of Cardiology, Dr. McAlexander and colleagues at Johns Hopkins University, Baltimore, used electronic health data from the Geisinger Health System to identify 9,054 patients with heart failure seen between 2008 and 2015. Of these, 5,839 patients had an incident HF hospitalization and 3,215 served as controls. Geisinger operates 13 hospitals and two research centers in 45 of Pennsylvania’s 67 counties, serving more than 3 million of the state’s residents.
Patients’ residential addresses were used to identify latitude and longitude coordinates that were matched with 9,669 UNGD wells in Pennsylvania and the location of major and minor roadways. The researchers also calculated a measure of community socioeconomic deprivation.
