2.1 Million COVID Vaccine Doses Given in U.S.
The U.S. has distributed more than 11.4 million doses of the Pfizer and Moderna COVID-19 vaccines, and more than 2.1 million of those had been given to people as of December 28, according to the CDC.
The CDC’s COVID Data Tracker showed the updated numbers as of 9 a.m. on that day. The distribution total is based on the CDC’s Vaccine Tracking System, and the administered total is based on reports from state and local public health departments, as well as updates from five federal agencies: the Bureau of Prisons, Veterans Administration, Department of Defense, Department of State, and Indian Health Services.
Health care providers report to public health agencies up to 72 hours after the vaccine is given, and public health agencies report to the CDC after that, so there may be a lag in the data. The CDC’s numbers will be updated on Mondays, Wednesdays, and Fridays.
“A large difference between the number of doses distributed and the number of doses administered is expected at this point in the COVID vaccination program due to several factors,” the CDC says.
Delays could occur due to the reporting of doses given, how states and local vaccine sites are managing vaccines, and the pending launch of vaccination through the federal Pharmacy Partnership for Long-Term Care Program.
“Numbers reported on other websites may differ from what is posted on CDC’s website because CDC’s overall numbers are validated through a data submission process with each jurisdiction,” the CDC says.
On Dec. 26, the agency’s tally showed that 9.5 million doses had been distributed and 1.9 million had been given, according to Reuters.
Public health officials and health care workers have begun to voice their concerns about the delay in giving the vaccines.
“We certainly are not at the numbers that we wanted to be at the end of December,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, told CNNDec. 29.
Operation Warp Speed had planned for 20 million people to be vaccinated by the end of the year. Fauci said he hopes that number will be achieved next month.
“I believe that as we get into January, we are going to see an increase in the momentum,” he said.
Shipment delays have affected other priority groups as well. The New York Police Department anticipated a rollout Dec. 29, but it’s now been delayed since the department hasn’t received enough Moderna doses to start giving the shots, according to the New York Daily News.
“We’ve made numerous attempts to get updated information, and when we get further word on its availability, we will immediately keep our members appraised of the new date and the method of distribution,” Paul DiGiacomo, president of the Detectives’ Endowment Association, wrote in a memo to members on Dec. 28.
“Every detective squad has been crushed with [COVID-19],” he told the newspaper. “Within the last couple of weeks, we’ve had at least two detectives hospitalized.”
President-elect Joe Biden will receive a briefing from his COVID-19 advisory team, provide a general update on the pandemic, and describe his own plan for vaccinating people quickly during an address Dec. 29, a transition official told Axios. Biden has pledged to administer 100 million vaccine doses in his first 100 days in office.

CDC issues COVID-19 vaccine guidance for underlying conditions
The Centers for Disease Control and Prevention has issued updated guidance for people with underlying medical conditions who are considering getting the coronavirus vaccine.
“Adults of any age with certain underlying medical conditions are at increased risk for severe illness from the virus that causes COVID-19,” the CDC said in the guidance, posted on Dec. 26. “mRNA COVID-19 vaccines may be administered to people with underlying medical conditions provided they have not had a severe allergic reaction to any of the ingredients in the vaccine.”
Both the Pfizer and Moderna vaccines use mRNA, or messenger RNA.
The CDC guidance had specific information for people with HIV, weakened immune systems, and autoimmune conditions such as Guillain-Barré syndrome (GBS) and Bell’s palsy who are thinking of getting the vaccine.
People with HIV and weakened immune systems “may receive a COVID-19 vaccine. However, they should be aware of the limited safety data,” the CDC said.
There’s no information available yet about the safety of the vaccines for people with weakened immune systems. People with HIV were included in clinical trials, but “safety data specific to this group are not yet available at this time,” the CDC said.
Cases of Bell’s palsy, a temporary facial paralysis, were reported in people receiving the Pfizer and Moderna vaccines in clinical trials, the Food and Drug Administration said Dec. 17.
But the new CDC guidance said that the FDA “does not consider these to be above the rate expected in the general population. They have not concluded these cases were caused by vaccination. Therefore, persons who have previously had Bell’s palsy may receive an mRNA COVID-19 vaccine.”
Researchers have determined the vaccines are safe for people with GBS, a rare autoimmune disorder in which the body’s immune system attacks nerves just as they leave the spinal cord, the CDC said.
“To date, no cases of GBS have been reported following vaccination among participants in the mRNA COVID-19 vaccine clinical trials,” the CDC guidance said. “With few exceptions, the independent Advisory Committee on Immunization Practices general best practice guidelines for immunization do not include a history of GBS as a precaution to vaccination with other vaccines.”
For months, the CDC and other health authorities have said that people with certain medical conditions are at an increased risk of developing severe cases of COVID-19.

"Lipid paradox” seen in nonobese RA patients with low LDL
Oxidative stress may account for the “lipid paradox,” a higher incidence of heart disease burden found in nonobese rheumatoid arthritis (RA) patients with lower levels of low-density lipoprotein (LDL). George Karpouzas, MD, an investigator at the Lundquist Institute of Biomedical Innovation, St, Torrance, Calif., discussed this exploratory finding at the virtual annual meeting of the American College of Rheumatology.
A complex dynamic exists between traditional risk factors and cardiovascular (CV) events in RA patients, said Dr. Karpouzas, professor of medicine at the University of California, Los Angeles, and chief of the division of rheumatology, Harbor-UCLA Medical Center. “Lower lipid levels, specifically total cholesterol and to a lesser extent LDL, may be associated with higher risk,” he said. One recent study found that coronary artery calcium (CAC) scores were four times higher in RA patients with lower LDL concentrations (> 70 mg/dL) than those in control groups. “This was especially true in patients who were nonobese, non-Hispanic Whites and never smokers,” said Dr. Karpouzas. Other studies have reported this association between low LDL and increased CVD risk.
These paradoxes led to several questions: Does obesity modify the effect of LDL on cardiovascular disease (CVD) risk in RA and does it moderate the effect of LDL on coronary plaque burden and progression? Do LDL particle composition and oxidation variations underlie the paradoxical association of low LDL with higher coronary atherosclerosis burden in RA? To find answers, Dr. Karpouzas’ team in the Prospective Evaluation of Latent Coronary Atherosclerosis in Rheumatoid Arthritis (PROTECT-RA) trial studied a cohort of 150 established RA patients without symptoms or diagnosis of CV disease.
Dr. Karpouzas presented two oral abstracts that summarized this research during the ACR 2020 session, “RA, diagnosis, manifestations and outcomes: heart of the matter,” which was held virtually.
Higher plaque burden seen in nonobese patients
In one part of the study, patients underwent baseline cardiac coronary CT angiography (CTA) over 1 year (2010-2011). Investigators evaluated CAC scores, segment involvement scores (SIS), segment stenosis scores (SSS), and extensive and obstructive disease. Low LDL was defined as < 70 mg/dL, obesity as a waist to height ratio of > 0.58 squared.
Investigators in follow-up work (2017-2018) evaluated for plaque progression, prospectively recording all cardiovascular disease events such as cardiac death, myocardial infarction, unstable angina, stroke, and heart failure hospitalization. Multivariable models assessed the effects of LDL lower than 70 mg/dL, obesity, and their interaction, accounting for factors such as age, sex, statin use, diabetes and hypertension.
Four LDL obesity cohorts
Nonobese RA patients with low LDL exhibited the highest plaque burden. “Despite no differences in RA inflammation, patients in this group were more likely to exhibit high levels of LDL oxidation,” Dr. Karpouzas said in an interview. “Nonobese patients with low LDL more likely exhibited new coronary plaque formation as well as increased stenotic severity of prevalent plaque after adjustments for relevant covariates,” he added.
The study’s observational nature exposed it to biases and unmeasured confounding, Dr. Karpouzas emphasized. Because it took place in a single center, the results might not be generalizable to ethnically and racially diverse cohorts. Patients with calcifications, extensive or obstructive coronary plaque at baseline scan received more aggressive treatments, which could have slowed CVD event risk and plaque progression. Investigators cautioned that the results should be seen as “exploratory,” given that CVD event analysis wasn’t applied to the original study design.
The oxidation-LDL connection
Another arm of the study examined the oxidation association question. Investigators did a similar analysis of the same patients but also evaluated for cholesterol content, Lp(a) mass, OxLDL levels, IgG and IgM anti-OxLDL and apoB100 immune complexes and proinflammatory cytokines.
RA patients with LDL lower than 70 mg/dL had higher SSS and CAC scores and were more likely to have extensive or obstructive plaque. Statin-naive patients with lower LDL exhibited greater LDL oxidation than higher LDL groups. In addition, those with lower LDL had higher anti-OxLDL and apoB100 than patients with higher LDL.
“Oxidation makes the cholesterol more ‘sticky,’ allowing it to penetrate into the walls of the endothelium, and changes macrophages to foam cells. This malignant process is very powerful and can potentially increase atheroma burden,” study coauthor Matthew Budoff, MD, professor of medicine at UCLA and endowed chair of preventive cardiology at the Lundquist Institute, said in an interview.
Investigators also found an independent association between Lp(a) content and LDL oxidation. This association seemed strong in patients with lower LDL compared to higher LDL groups. In addition, “greater oxidation and immune recognition of oxLDL further associated with higher IL-6 elaboration which may in turn augment atherosclerosis burden in the low LDL group,” said Dr. Karpouzas.
The analysis did not explore alternate mechanisms such as increased cholesterol loading capacity, lower efflux capacity or increased hepatocyte uptake through LDL-R upregulation, a key limitation. Dr. Karpouzas also acknowledged that higher cumulative inflammatory burden incurred before evaluating low LDL patients at baseline may have led to greater coronary plaque burden.
Overall, the study shows that low LDL is not protective in this population, said Dr. Budoff. “Low LDL patients who have atherosclerosis should be treated with statins and other therapies to lower their CV risk.”
Larger studies to confirm associations
Attendees of the ACR 2020 session called for additional studies to confirm that LDL oxidation leads to increased coronary atherosclerotic burden in RA patients.
The study provides “mechanistic insight into this important problem for patients with RA,” noted Jeffrey A. Sparks, MD, MMSc, assistant professor of medicine at Harvard Medical School and associate physician at Brigham and Women’s Hospital, Boston.
Some of the patients studied were on lipid-lowering drugs such as statins, though the statistical analysis adjusted for use of these medications, noted Dr. Sparks. “It is possible that excess systemic inflammation alone is responsible for changes in LDL oxidation that may ultimately lead to cardiovascular disease,” he offered.
Future mechanistic and interventional studies related specifically to LDL oxidation “should establish the importance of this pathway in the development of cardiovascular disease in patients with RA,” said Dr. Sparks.
Large studies of patients with different BMI and LDL values followed prospectively for CV events would be ideal, said Joel M. Kremer, MD, president of the Corrona Research Foundation and founder of Corrona, a biopharma data solutions firm. Investigators would need to follow patients for several years. And, such a venture might face some obstacles. “The practical impediments and cost would be substantial. Also, as LDL oxidation may be related to disease activity, there would be ethical and pragmatic issues associated with controlling disease activity in these patients. This would obscure these outcomes of interest,” said Dr. Kremer.

“Oxidation makes the cholesterol more ‘sticky,’ allowing it to penetrate into the walls of the endothelium, and changes macrophages to foam cells. This malignant process is very powerful and can potentially increase atheroma burden,” study coauthor Matthew Budoff, MD, professor of medicine at UCLA and endowed chair of preventive cardiology at the Lundquist Institute, said in an interview.
Investigators also found an independent association between Lp(a) content and LDL oxidation. This association seemed strong in patients with lower LDL compared to higher LDL groups. In addition, “greater oxidation and immune recognition of oxLDL further associated with higher IL-6 elaboration which may in turn augment atherosclerosis burden in the low LDL group,” said Dr. Karpouzas.
The analysis did not explore alternate mechanisms such as increased cholesterol loading capacity, lower efflux capacity or increased hepatocyte uptake through LDL-R upregulation, a key limitation. Dr. Karpouzas also acknowledged that higher cumulative inflammatory burden incurred before evaluating low LDL patients at baseline may have led to greater coronary plaque burden.
Overall, the study shows that low LDL is not protective in this population, said Dr. Budoff. “Low LDL patients who have atherosclerosis should be treated with statins and other therapies to lower their CV risk.”
Larger studies to confirm associations
Attendees of the ACR 2020 session called for additional studies to confirm that LDL oxidation leads to increased coronary atherosclerotic burden in RA patients.
The study provides “mechanistic insight into this important problem for patients with RA,” noted Jeffrey A. Sparks, MD, MMSc, assistant professor of medicine at Harvard Medical School and associate physician at Brigham and Women’s Hospital, Boston.
Some of the patients studied were on lipid-lowering drugs such as statins, though the statistical analysis adjusted for use of these medications, noted Dr. Sparks. “It is possible that excess systemic inflammation alone is responsible for changes in LDL oxidation that may ultimately lead to cardiovascular disease,” he offered.
Future mechanistic and interventional studies related specifically to LDL oxidation “should establish the importance of this pathway in the development of cardiovascular disease in patients with RA,” said Dr. Sparks.
Large studies of patients with different BMI and LDL values followed prospectively for CV events would be ideal, said Joel M. Kremer, MD, president of the Corrona Research Foundation and founder of Corrona, a biopharma data solutions firm. Investigators would need to follow patients for several years. And, such a venture might face some obstacles. “The practical impediments and cost would be substantial. Also, as LDL oxidation may be related to disease activity, there would be ethical and pragmatic issues associated with controlling disease activity in these patients. This would obscure these outcomes of interest,” said Dr. Kremer.

Scant risk for SARS-CoV-2 from hospital air
Everywhere they look within hospitals, researchers find RNA from SARS-CoV-2 in the air. But viable viruses typically are found only close to patients, according to a review of published studies.
The finding supports recommendations to use surgical masks in most parts of the hospital, reserving respirators (such as N95 or FFP2) for aerosol-generating procedures on patients’ respiratory tracts, said Gabriel Birgand, PhD, an infectious disease researcher at Imperial College London.
“When the virus is spreading a lot in the community, it’s probably more likely for you to be contaminated in your friends’ areas or in your building than in your work area, where you are well equipped and compliant with all the measures,” he said in an interview. “So it’s pretty good news.”
The systematic review by Dr. Birgand and colleagues was published in JAMA Network Open.
Recommended precautions to protect health care workers from SARS-CoV-2 infections remain controversial. Most authorities believe droplets are the primary route of transmission, which would mean surgical masks may be sufficient protection. But some research has suggested transmission by aerosols as well, making N95 respirators seem necessary. There is even disagreement about the definitions of the words “aerosol” and “droplet.”
To better understand where traces of the virus can be found in the air in hospitals, Dr. Birgand and colleagues analyzed all the studies they could find on the subject in English.
They identified 24 articles with original data. All of the studies used reverse transcription–polymerase chain reaction (PCR) tests to identify SARS-CoV-2 RNA. In five studies, attempts were also made to culture viable viruses. Three studies assessed the particle size relative to RNA concentration or viral titer.
Of 893 air samples across the 24 studies, 52.7% were taken from areas close to patients, 26.5% were taken in clinical areas, 13.7% in staff areas, 4.7% in public areas, and 2.4% in toilets or bathrooms.
Among those studies that quantified RNA, the median interquartile range of concentrations varied from 1.0 x 103 copies/m3 in clinical areas to 9.7 x 103 copies/m3 in toilets or bathrooms.
One study found an RNA concentration of 2.0 x 103 copies for particle sizes >4 mcm and 1.3 x 103 copies/m3 for particle sizes ≤4 mcm, both in patients’ rooms.
Three studies included viral cultures; of those, two resulted in positive cultures, both in a non-ICU setting. In one study, 3 of 39 samples were positive, and in the other, 4 of 4 were positive. Viral cultures in toilets, clinical areas, staff areas, and public areas were negative.
One of these studies assessed viral concentration and found that the median interquartile range was 4.8 tissue culture infectious dose (TCID50)/m3 for particles <1 mcm, 4.27 TCID50/m3 for particles 1-4 mcm, and 1.82 TCID50/m3 for particles >4 mcm.
Although viable viruses weren’t found in staff areas, the presence of viral RNA in places such as dining rooms and meeting rooms raises a concern, Dr. Birgand said.
“All of these staff areas are probably playing an important role in contamination,” he said. “It’s pretty easy to see when you are dining, you are not wearing a face mask, and it’s associated with a strong risk when there is a strong dissemination of the virus in the community.”
Studies on contact tracing among health care workers have also identified meeting rooms and dining rooms as the second most common source of infection after community contact, he said.
In general, the findings of the review correspond to epidemiologic studies, said Angela Rasmussen, PhD, a virologist with the Georgetown University Center for Global Health Science and Security, Washington, who was not involved in the review. “Absent aerosol-generating procedures, health care workers are largely not getting infected when they take droplet precautions.”
One reason may be that patients shed the most infectious viruses a couple of days before and after symptoms begin. By the time they’re hospitalized, they’re less likely to be contagious but may continue to shed viral RNA.
“We don’t really know the basis for the persistence of RNA being produced long after people have been infected and have recovered from the acute infection,” she said, “but it has been observed quite frequently.”
Although the virus cannot remain viable for very long in the air, remnants may still be detected in the form of RNA, Dr. Rasmussen said. In addition, hospitals often do a good job of ventilation.
She pointed out that it can be difficult to cultivate viruses in air samples because of contaminants such as bacteria and fungi. “That’s one of the limitations of a study like this. You’re not really sure if it’s because there’s no viable virus there or because you just aren’t able to collect samples that would allow you to determine that.”
Dr. Birgand and colleagues acknowledged other limitations. The studies they reviewed used different approaches to sampling. Different procedures may have been underway in the rooms being sampled, and factors such as temperature and humidity could have affected the results. In addition, the studies used different cycle thresholds for PCR positivity.

New resilience center targets traumatized health care workers
A physician assistant participating in a virtual workshop began to cry, confessing that she felt overwhelmed with guilt because New Yorkers were hailing her as a frontline hero in the pandemic. That was when Joe Ciavarro knew he was in the right place.
“She was saying all the things I could not verbalize because I, too, didn’t feel like I deserved all this praise and thousands of people cheering for us every evening when people were losing jobs, didn’t have money for food, and their loved ones were dying without family at their side,” says Mr. Ciavarro, a PA at Mount Sinai Medical Center in New York.
Mr. Ciavarro, who also manages 170 other PAs on two of Mount Sinai’s campuses in Manhattan, has been on the front lines since COVID-19 first hit; he lost a colleague and friend to suicide in September.
The mental anguish from his job prompted him to sign up for the resilience workshop offered by Mount Sinai’s Center for Stress, Resilience, and Personal Growth. The center – the first of its kind in North America – was launched in June to help health care workers like him cope with the intense psychological pressures they were facing. The weekly workshops became a safe place where Mr. Ciavarro and other staff members could share their darkest fears and learn ways to help them deal with their situation.
“It’s been grueling but we learned how to take care of ourselves so we can take care of our patients,” said Mr. Ciavarro. “This has become like a guided group therapy session on ways to manage and develop resilience. And I feel like my emotions are validated, knowing that others feel the same way.”
Caring for their own
Medical professionals treating patients with COVID-19 are in similar predicaments, and the psychological fallout is enormous: They’re exhausted by the seemingly never-ending patient load and staffing shortages, and haunted by fears for their own safety and that of their families. Studies in China, Canada, and Italy have revealed that a significant number of doctors and nurses in the early days of the pandemic experienced high levels of distress, depression, anxiety, nightmares, and insomnia.
after witnessing the deaths of so many patients who were alone, without family.
But the resilience workshop that Mr. Ciavarro attended offers some hope and is part of a multifaceted program that aims to be a model for other institutions and communities. The Mount Sinai health system already had some programs in place, including centers for 9/11 responders, for spirituality and health, and a wellness program to aid burned-out doctors. But the leadership at Mount Sinai, which includes psychiatrist Dennis Charney, MD, dean of the medical school and a leading expert on PTSD, knew early in the pandemic that emotional and psychological distress would plague health care workers, according to Deborah Marin, MD, director of the new center.
“We decided to quickly put in place a program that we could do virtually, with workshops and apps, that would give access to several services above and beyond what was already going on,” says Dr. Marin, a professor of psychiatry at the Icahn School of Medicine at Mount Sinai, New York, who also directs their center for spirituality and health.
The key components include a comprehensive screening tool that helps doctors at the center identify which potential participants are most at risk. Participants build personal inventories that detail the intensity of work-related exposures, personal or family stressors that have arisen because of the pandemic, or any mental health conditions or substance abuse problems that may make staff members more vulnerable.
The weekly workshops led by trained staff are designed to give participants the tools to foster resilience and process their experiences. Online apps provide feedback on their progress and engage them with video and other resources around meditation, relaxation, and resilience techniques.
In addition, all 40,000 members of the Mount Sinai staff are eligible for up to 14 one-on-one sessions with psychologists and psychiatrists who specialize in treating trauma.
“That’s highly unusual – to offer this at no cost to everyone,” said Dr. Marin. “We also have a treatment service that is specifically focused on behavioral health care, so people can learn better coping strategies, and we also have social workers to provide coaching.”
While the center doesn’t have specific numbers on how many nurses, physicians, and other staff have participated in treatment, they have trained over 70 peer leaders for their five workshops that home in on the most important factors of resilience.
“We’ve gotten enthusiastic responses from PAs and nurses,” said Craig Katz, MD, an expert in disaster psychiatry at Mount Sinai and a workshop moderator. Physicians have been slower to get on board. “Doctors are a tough nut to crack – it’s largely a culture where they may burn out but don’t want to talk about it. And asking for help is a hard transition for physicians to make.”
How to protect in midst of trauma
In formulating the program’s platform, Mount Sinai experts drew upon their extensive experience aiding 9/11 responders at the World Trade Center (WTC), as well as their system-wide wellness program that aids demoralized and burned-out physicians. While the reach of the pandemic is much broader than 9/11, experts see some commonalities in conditions that emerge after traumatic events, and they also discovered what can help.
“We learned from our WTC experience about what are protective factors – what are the social supports that buffer against depression, anxiety, and PTSD,” said Jonathan DePierro, PhD, clinical director of CSRPG and a psychologist at the Mount Sinai WTC Mental Health Program. “We also learned that people who have more prolonged exposures are at greater risk of developing mental health difficulties.”
The program itself reflects these lessons – and that’s why it’s open to all employees, not just medical professionals. Housekeepers, security staffers, even construction workers are also dealing with their lives being in danger. “That wasn’t in their job description,” said Dr. DePierro. “These people tend to have fewer social and economic resources, make less money and have fewer structural supports, which makes them even more vulnerable.”
Dr. Charney’s strategies on building resilience became a bible of sorts for the workshops, according to Dr. Katz, who authored the training curriculum. Sessions deal with how to build up reservoirs of realistic optimism, keep gratitude journals, find spiritual meaning in their lives, maintain physical wellness and create networks of social support. The workshops are meant to help participants create action plans, to reach out for support in their social networks, and keep the focus on the positives.
The goal is to give demoralized health care workers a renewed sense of competence. “The resilience workshop is a launching point to get people to show up and talk,” said Dr. Katz. “And if we do that, we’ve accomplished a lot just getting people in the door.”
The center will also have a research component to identify what works and what doesn’t so their platform can provide a template for other institutions; Dr. Marin said they’ve gotten inquiries about the program from major hospital systems in Michigan and California. They’ll also conduct longitudinal research to determine what lingering problems persist among healthcare workers over time.
Since the center opened its virtual doors, the curriculum has also been altered in response to feedback from the support staff, many of whom live in the community that surrounds Mount Sinai in northern Manhattan, which is largely lower-income Latinx and Black individuals. Workshop materials have been translated into Spanish and now feature people who reflect a more diverse set of experiences.
“Many of our employees and the population we serve identify as non-White so we’ve been doing outreach with a lot of the local unions,” said Dr. Marin. “Our next step is to take what we’re doing and work with local community organizations.”

after witnessing the deaths of so many patients who were alone, without family.
But the resilience workshop that Mr. Ciavarro attended offers some hope and is part of a multifaceted program that aims to be a model for other institutions and communities. The Mount Sinai health system already had some programs in place, including centers for 9/11 responders, for spirituality and health, and a wellness program to aid burned-out doctors. But the leadership at Mount Sinai, which includes psychiatrist Dennis Charney, MD, dean of the medical school and a leading expert on PTSD, knew early in the pandemic that emotional and psychological distress would plague health care workers, according to Deborah Marin, MD, director of the new center.
“We decided to quickly put in place a program that we could do virtually, with workshops and apps, that would give access to several services above and beyond what was already going on,” says Dr. Marin, a professor of psychiatry at the Icahn School of Medicine at Mount Sinai, New York, who also directs their center for spirituality and health.
The key components include a comprehensive screening tool that helps doctors at the center identify which potential participants are most at risk. Participants build personal inventories that detail the intensity of work-related exposures, personal or family stressors that have arisen because of the pandemic, or any mental health conditions or substance abuse problems that may make staff members more vulnerable.
The weekly workshops led by trained staff are designed to give participants the tools to foster resilience and process their experiences. Online apps provide feedback on their progress and engage them with video and other resources around meditation, relaxation, and resilience techniques.
In addition, all 40,000 members of the Mount Sinai staff are eligible for up to 14 one-on-one sessions with psychologists and psychiatrists who specialize in treating trauma.
“That’s highly unusual – to offer this at no cost to everyone,” said Dr. Marin. “We also have a treatment service that is specifically focused on behavioral health care, so people can learn better coping strategies, and we also have social workers to provide coaching.”
While the center doesn’t have specific numbers on how many nurses, physicians, and other staff have participated in treatment, they have trained over 70 peer leaders for their five workshops that home in on the most important factors of resilience.
“We’ve gotten enthusiastic responses from PAs and nurses,” said Craig Katz, MD, an expert in disaster psychiatry at Mount Sinai and a workshop moderator. Physicians have been slower to get on board. “Doctors are a tough nut to crack – it’s largely a culture where they may burn out but don’t want to talk about it. And asking for help is a hard transition for physicians to make.”
How to protect in midst of trauma
In formulating the program’s platform, Mount Sinai experts drew upon their extensive experience aiding 9/11 responders at the World Trade Center (WTC), as well as their system-wide wellness program that aids demoralized and burned-out physicians. While the reach of the pandemic is much broader than 9/11, experts see some commonalities in conditions that emerge after traumatic events, and they also discovered what can help.
“We learned from our WTC experience about what are protective factors – what are the social supports that buffer against depression, anxiety, and PTSD,” said Jonathan DePierro, PhD, clinical director of CSRPG and a psychologist at the Mount Sinai WTC Mental Health Program. “We also learned that people who have more prolonged exposures are at greater risk of developing mental health difficulties.”
The program itself reflects these lessons – and that’s why it’s open to all employees, not just medical professionals. Housekeepers, security staffers, even construction workers are also dealing with their lives being in danger. “That wasn’t in their job description,” said Dr. DePierro. “These people tend to have fewer social and economic resources, make less money and have fewer structural supports, which makes them even more vulnerable.”
Dr. Charney’s strategies on building resilience became a bible of sorts for the workshops, according to Dr. Katz, who authored the training curriculum. Sessions deal with how to build up reservoirs of realistic optimism, keep gratitude journals, find spiritual meaning in their lives, maintain physical wellness and create networks of social support. The workshops are meant to help participants create action plans, to reach out for support in their social networks, and keep the focus on the positives.
The goal is to give demoralized health care workers a renewed sense of competence. “The resilience workshop is a launching point to get people to show up and talk,” said Dr. Katz. “And if we do that, we’ve accomplished a lot just getting people in the door.”
The center will also have a research component to identify what works and what doesn’t so their platform can provide a template for other institutions; Dr. Marin said they’ve gotten inquiries about the program from major hospital systems in Michigan and California. They’ll also conduct longitudinal research to determine what lingering problems persist among healthcare workers over time.
Since the center opened its virtual doors, the curriculum has also been altered in response to feedback from the support staff, many of whom live in the community that surrounds Mount Sinai in northern Manhattan, which is largely lower-income Latinx and Black individuals. Workshop materials have been translated into Spanish and now feature people who reflect a more diverse set of experiences.
“Many of our employees and the population we serve identify as non-White so we’ve been doing outreach with a lot of the local unions,” said Dr. Marin. “Our next step is to take what we’re doing and work with local community organizations.”

Temper enthusiasm for long-term treatment with bisphosphonates?
Women treated with oral bisphosphonate drugs for osteoporosis for 5 years get no additional benefit – in terms of hip fracture risk – if the treatment is extended for another 5 years, new research shows.
“We found that hip fracture risk in women did not differ if women stopped bisphosphonate use after 5 years or stayed on the medication for 10 years,” coauthor Joan C. Lo, MD, Kaiser Permanente Northern California, Oakland, said in an interview.
The new study, published Dec. 7 in JAMA Network Open, did show a small benefit in continuing the treatment through 7 years vs. 5 years, but it wasn’t clear if this was significant.
“Whether there is a benefit to staying on the drug for 7 years needs to be further studied in randomized trials,” Dr. Lo stressed.
It is well established that oral bisphosphonates are effective in reducing the risk for fracture within the first 3-5 years of treatment; however, evidence on the effects of treatment beyond 5 years is lacking.
The most recent guidance from the American Society of Bone and Mineral Research (ASBMR) on the issue, which were released in 2015, recommends continuation of bisphosphonates beyond 5 years for high-risk patients, but it recommends a “drug holiday” for low-risk patients.
Study adds important new evidence
However, that guidance acknowledges that data are limited regarding long-term use. This large new study adds important new evidence to the discussion, Robert A. Adler, MD, who was a member of the ASBMR Task Force for the recent guidance, said in an interview.
“[With the lack of recent research,] this new study from Kaiser Permanente is of great interest,” said Dr. Adler, chief of endocrinology and metabolism at Central Virginia Veterans Affairs Health Care System and professor of internal medicine and of epidemiology at Virginia Commonwealth University, Richmond.
“It is new data and suggests we might temper our enthusiasm for long-term treatment with bisphosphonates,” he said.
“Importantly, it is the first large observational trial and is closer to a real-world setting than a randomized controlled trial,” he said.
But, Dr. Adler emphasized: “The take-home message is that while this suggests that patients can probably be given a drug holiday for a couple of years ... they should be retested, and if they appear to be at an increased risk of fracture, they probably should restart again.
“Osteoporosis is a chronic disorder,” he emphasized. “It isn’t cured by any of our treatments, and as people get older, they are at a higher fracture risk.
“So we really need to follow our patients for a lifetime and reassess their fracture risk every couple of years – whether they are still on therapy or on a drug holiday.”
Possible that 7 years is better than 5 but remains to be proven
The new study involved data from Kaiser Permanente Northern and Southern California on 29,685 women who had completed 5 years of treatment with oral bisphosphonates, including alendronate, risedronate, or ibandronate, between 2002 and 2014.
Among the women, 11,105 (37%) continued taking the drugs beyond 5 years to 7 years, and 2,725 (9.2%) completed a total of 10 years of treatment.
Their median age was 71. Among those for whom bone mineral density data were available, 37% had osteoporosis after the first 5 years of treatment.
During these 5 years of treatment, 507 hip fractures occurred.
The cumulative incidence of hip fracture among for those who discontinued study therapy at entry, i.e., those who underwent treatment for 5 years, was 23.0 per 1,000 individuals.
After 7 years of treatment, the rate was 20.8 per 1000. For those who continued therapy for 10 years, the rate was 26.8 per 1000 individuals.
The rate in the 7-year treatment group was based on patients taking a 6-month drug holiday after the initial 5 years, but the results are hard to interpret, Dr. Lo said.
“It’s possible that 7 years is better than 5, but this is not a randomized trial, and some of the data analyses done in the study suggest more research should be done to look at a benefit after 7 years.
“At the end of the day, doctors and women need to decide at 5 years what an individual woman’s risk fracture risk is and determine if she should stay on the drug longer,” Dr. Lo emphasized.
Limitations: Subgroups not identified, adherence hard to assess
The uncertainty of any benefit of treatment with bisphosphonates beyond 5 years is further reflected in U.S. recommendations – the Food and Drug Administration has concluded on the basis of pooled data from the extension phase of major clinical trials that any advantages of treatment beyond 3-5 years are unclear.
Key limitations of the current study include the fact that the incidence of hip fracture was not evaluated in low-risk vs. high-risk subgroups; therefore, “these findings may not be applicable to older women at higher risk of osteoporotic fracture,” the authors wrote.
Furthermore, the study did not assess outcomes of fractures other than hip fractures, such as vertebral fractures, they noted.
Dr. Adler pointed out that another limitation is that adherence in the trial was defined as taking 60% of prescribed pills.
“I think this is the biggest weakness with the study,” he said. “Particularly with medications like oral bisphosphonates that don’t really make patients feel any different, it’s a real challenge to make sure patients continue to take these drugs properly.”
The findings should give some reassurance for patients who take a break from the drugs after 5 years. However, reassessment of their risk is critical, Dr. Adler reiterated.
The study was supported by a grant from the National Institute on Aging and the National Institute of Arthritis, Musculoskeletal, and Skin Diseases of the National Institutes of Health. The authors and Adler have disclosed no relevant financial relationships.

Swedish registry study finds atopic dermatitis significantly associated with autoimmune diseases
in a case control study derived from Swedish national health care registry data.
Atopic dermatitis (AD) is known to be associated with other atopic conditions, and there is increasing evidence it is associated with some nonatopic conditions, including some cancers, cardiovascular disease, and neuropsychiatric disorders, according to Lina U. Ivert, MD, of the dermatology and venereology unit at the Karolinska Institutet, Stockholm, and coauthors. There are also some data indicating that autoimmune diseases, particularly those involving the skin and gastrointestinal tract, are more common in people with AD.
The aim of their study, published in the British Journal of Dermatology, was to investigate a wide spectrum of autoimmune diseases for associations with AD in a large-scale, population-based study using Swedish registers. Findings could lead to better monitoring of comorbidities and deeper understanding of disease burden and AD pathophysiology, they noted.
Large-scale study
With data from the Swedish Board of Health and Welfare’s National Patient Register on inpatient diagnoses since 1964 and specialist outpatient visits since 2001, the investigators included all patients aged 15 years and older with AD diagnoses (104,832) and matched them with controls from the general population (1,022,435). The authors noted that the large number of people included in the analysis allowed for robust estimates, and underscored that 80% of the AD patients included had received their diagnosis in a dermatology department, which reduces the risk of misclassification.
Association with autoimmune disease
The investigators found an association between AD and autoimmune disease, with an adjusted odds ratio) of 1.97 (95% confidence interval, 1.93-2.01). The association was present with several organ systems, particularly the skin and gastrointestinal tract, and with connective tissue diseases. The strongest associations with autoimmune skin diseases were found for dermatitis herpetiformis (aOR, 9.76; 95% CI, 8.10-11.8), alopecia areata (aOR, 5.11; 95% CI, 4.75-5.49), and chronic urticaria (aOR, 4.82; 95% CI, 4.48-5.19).
AD was associated with gastrointestinal diseases, including celiac disease (aOR, 1.96; 95% CI, 1.84-2.09), Crohn disease (aOR 1.83; CI, 1.71-1.96), and ulcerative colitis (aOR 1.58; 95% CI, 1.49-1.68).
Connective tissue diseases significantly associated with AD included systemic lupus erythematosus (aOR, 1.65; 95% CI, 1.42-1.90), ankylosing spondylitis (aOR, 1.46; 95% CI, 1.29-1.66), and RA (aOR, 1.44; 95% CI,1.34-1.54]). Hematologic or hepatic autoimmune disease associations with AD were not observed.
Stronger association with multiple diseases
The association between AD and two or more autoimmune diseases was significantly stronger than the association between AD and having one autoimmune disease. For example, the OR for AD among people with three to five autoimmune diseases was 3.33 (95% CI, 2.86-3.87), and was stronger in men (OR, 3.96; 95% CI, 2.92-5.37) than in women (OR, 3.14; 95% CI, 2.63-3.74).
Sex differences
In the study overall, the association with AD and autoimmune diseases was stronger in men (aOR, 2.18; 95% CI, 2.10-2.25), compared with women (aOR, 1.89; 95% CI, 1.85-1.93), but this “sex difference was only statistically significant between AD and RA and between AD and Celiac disease,” they noted.
Associations between AD and dermatomyositis, systemic scleroderma, systemic lupus erythematosus, Hashimoto’s disease, Graves disease, multiple sclerosis, and polymyalgia rheumatica were found only in women. Dr. Ivert and coauthors observed that “women are in general more likely to develop autoimmune diseases, and 80% of patients with autoimmune diseases are women.”
Provocative questions
Commenting on the findings, Jonathan Silverberg, MD, PhD, MPH, associate professor of dermatology, George Washington University, Washington, said, “At a high level, it is important for clinicians to recognize that atopic dermatitis is a systemic immune-mediated disease. AD is associated with higher rates of comorbid autoimmune disease, similar to psoriasis and other chronic inflammatory skin diseases.”
“At this point, there is nothing immediately actionable about these results,” noted Dr. Silverberg, who was not an author of this study. “That said, in my mind, they raise some provocative questions: What is the difference between AD in adults who do versus those who do not get comorbid autoimmune disease? Does AD then present differently? Does it respond to the same therapies? These will have to be the subject of future research.”
The study was funded by the Swedish Asthma and Allergy Association Research Foundation, Hudfonden (the Welander-Finsen Foundation), and the Swedish Society for Dermatology and Venereology. The authors disclosed no conflicts of interest.

Ivert, MD, of the dermatology and venereology unit at the Karolinska Institutet, Stockholm, and coauthors. There are also some data indicating that autoimmune diseases, particularly those involving the skin and gastrointestinal tract, are more common in people with AD.
The aim of their study, published in the British Journal of Dermatology, was to investigate a wide spectrum of autoimmune diseases for associations with AD in a large-scale, population-based study using Swedish registers. Findings could lead to better monitoring of comorbidities and deeper understanding of disease burden and AD pathophysiology, they noted.
Large-scale study
With data from the Swedish Board of Health and Welfare’s National Patient Register on inpatient diagnoses since 1964 and specialist outpatient visits since 2001, the investigators included all patients aged 15 years and older with AD diagnoses (104,832) and matched them with controls from the general population (1,022,435). The authors noted that the large number of people included in the analysis allowed for robust estimates, and underscored that 80% of the AD patients included had received their diagnosis in a dermatology department, which reduces the risk of misclassification.
Association with autoimmune disease
The investigators found an association between AD and autoimmune disease, with an adjusted odds ratio) of 1.97 (95% confidence interval, 1.93-2.01). The association was present with several organ systems, particularly the skin and gastrointestinal tract, and with connective tissue diseases. The strongest associations with autoimmune skin diseases were found for dermatitis herpetiformis (aOR, 9.76; 95% CI, 8.10-11.8), alopecia areata (aOR, 5.11; 95% CI, 4.75-5.49), and chronic urticaria (aOR, 4.82; 95% CI, 4.48-5.19).
AD was associated with gastrointestinal diseases, including celiac disease (aOR, 1.96; 95% CI, 1.84-2.09), Crohn disease (aOR 1.83; CI, 1.71-1.96), and ulcerative colitis (aOR 1.58; 95% CI, 1.49-1.68).
Connective tissue diseases significantly associated with AD included systemic lupus erythematosus (aOR, 1.65; 95% CI, 1.42-1.90), ankylosing spondylitis (aOR, 1.46; 95% CI, 1.29-1.66), and RA (aOR, 1.44; 95% CI,1.34-1.54]). Hematologic or hepatic autoimmune disease associations with AD were not observed.
Stronger association with multiple diseases
The association between AD and two or more autoimmune diseases was significantly stronger than the association between AD and having one autoimmune disease. For example, the OR for AD among people with three to five autoimmune diseases was 3.33 (95% CI, 2.86-3.87), and was stronger in men (OR, 3.96; 95% CI, 2.92-5.37) than in women (OR, 3.14; 95% CI, 2.63-3.74).
Sex differences
In the study overall, the association with AD and autoimmune diseases was stronger in men (aOR, 2.18; 95% CI, 2.10-2.25), compared with women (aOR, 1.89; 95% CI, 1.85-1.93), but this “sex difference was only statistically significant between AD and RA and between AD and Celiac disease,” they noted.
Associations between AD and dermatomyositis, systemic scleroderma, systemic lupus erythematosus, Hashimoto’s disease, Graves disease, multiple sclerosis, and polymyalgia rheumatica were found only in women. Dr. Ivert and coauthors observed that “women are in general more likely to develop autoimmune diseases, and 80% of patients with autoimmune diseases are women.”
Provocative questions
Commenting on the findings, Jonathan Silverberg, MD, PhD, MPH, associate professor of dermatology, George Washington University, Washington, said, “At a high level, it is important for clinicians to recognize that atopic dermatitis is a systemic immune-mediated disease. AD is associated with higher rates of comorbid autoimmune disease, similar to psoriasis and other chronic inflammatory skin diseases.”
“At this point, there is nothing immediately actionable about these results,” noted Dr. Silverberg, who was not an author of this study. “That said, in my mind, they raise some provocative questions: What is the difference between AD in adults who do versus those who do not get comorbid autoimmune disease? Does AD then present differently? Does it respond to the same therapies? These will have to be the subject of future research.”
The study was funded by the Swedish Asthma and Allergy Association Research Foundation, Hudfonden (the Welander-Finsen Foundation), and the Swedish Society for Dermatology and Venereology. The authors disclosed no conflicts of interest.

COVID-19 mortality rates declined, but vary by hospital
Mortality rates for inpatients with COVID-19 dropped significantly during the first 6 months of the pandemic, but outcomes depend on the hospital where patients receive care, new data show.
“[T]he characteristic that is most associated with poor or worsening hospital outcomes is high or increasing community case rates,” write David A. Asch, MD, MBA, executive director of the Center for Health Care Innovation at the University of Pennsylvania in Philadelphia, and colleagues.
The relationship between COVID-19 mortality rates and local disease prevalence suggests that “hospitals do worse when they are burdened with cases and is consistent with imperatives to flatten the curve,” the authors continue. “As case rates of COVID-19 increase across the nation, hospital mortality outcomes may worsen.”
The researchers published their study online December 22 in JAMA Internal Medicine.
The quick and substantial improvement in survival “is a tribute in part to new science — for example, the science that revealed the benefits of dexamethasone,” Asch told Medscape Medical News. “But it’s also a tribute to the doctors and nurses in the hospitals who developed experience. It’s a cliché to refer to them as heroes, but that is what they are. The science and the heroic experience continues on, and so I’m optimistic that we’ll see even more improvement over time.”
However, the data also indicate that “with lots of disease in the community, hospitals may have a harder time keeping patients alive,” Asch said. “And of course the reason this is bad news is that community level case rates are rising all over, and in some cases at rapid rates. With that rise, we might be giving back some of our past gains in survival — just as the vaccine is beginning to be distributed.”
Examining mortality trends
The researchers analyzed administrative claims data from a large national health insurer. They included data from 38,517 adults who were admitted with COVID-19 to 955 US hospitals between January 1 and June 30 of this year. The investigators estimated hospitals’ risk-standardized rate of 30-day in-hospital mortality or referral to hospice, adjusted for patient-level characteristics.
Overall, 3179 patients (8.25%) died, and 1433 patients (3.7%) were referred to hospice. Risk-standardized mortality or hospice referral rates for individual hospitals ranged from 5.7% to 24.7%. The average rate was 9.1% in the best-performing quintile, compared with 15.7% in the worst-performing quintile.
In a subset of 398 hospitals that had at least 10 patients admitted for COVID-19 during early (January 1 through April 30) and later periods (between May 1 and June 30), rates in all but one hospital improved, and 94% improved by at least 25%. The average risk-standardized event rate declined from 16.6% to 9.3%.
“That rate of relative improvement is striking and encouraging, but perhaps not surprising,” Asch and coauthors write. “Early efforts at treating patients with COVID-19 were based on experience with previously known causes of severe respiratory illness. Later efforts could draw on experiences specific to SARS-CoV-2 infection.”
For instance, doctors tried different inpatient management approaches, such as early vs late assisted ventilation, differences in oxygen flow, prone or supine positioning, and anticoagulation. “Those efforts varied in how systematically they were evaluated, but our results suggest that valuable experience was gained,” the authors note.
In addition, variation between hospitals could reflect differences in quality or different admission thresholds, they continue.
The study provides “a reason for optimism that our healthcare system has improved in our ability to care for persons with COVID-19,” write Leon Boudourakis, MD, MHS, and Amit Uppal, MD, in a related commentary. Boudourakis and Uppal are both affiliated with NYC Health + Hospitals in New York City and with SUNY Downstate and New York University School of Medicine, respectively.
Similar improvements in mortality rates have been reported in the United Kingdom and in a New York City hospital system, the editorialists note. The lower mortality rates may represent clinical, healthcare system, and epidemiologic trends.
“Since the first wave of serious COVID-19 cases, physicians have learned a great deal about the best ways to treat this serious infection,” they say. “Steroids may decrease mortality in patients with respiratory failure. Remdesivir may shorten hospitalizations of patients with serious illness. Anticoagulation and prone positioning may help certain patients. Using noninvasive ventilation and high-flow oxygen therapy may spare subsets of patients from the harms of intubation, such as ventilator-induced lung injury.»
Overwhelmed hospitals
“Hospitals do not perform as well when they are overwhelmed,” which may be a reason for the correlation between community prevalence and mortality rates, Boudourakis and Uppal suggested. “In particular, patients with a precarious respiratory status require expert, meticulous therapy to avoid intubation; those who undergo intubation or have kidney failure require nuanced and timely expert care with ventilatory adjustments and kidney replacement therapy, which are difficult to perform optimally when hospital capacity is strained.”
Although the death rate has fallen to about 9% for hospitalized patients, “9% is still high,” Asch said.
“Our results show that hospitals can’t do it on their own,” Asch said. “They need all of us to keep the community spread of the disease down. The right answer now is the right answer since the beginning of the pandemic: Keep your distance, wash your hands, and wear a mask.”
Asch, Boudourakis, and Uppal have disclosed no relevant financial relationships. A study coauthor reported personal fees and grants from pharmaceutical companies outside the submitted work.

After COVID-19 infection, antibodies highly protective for months, prospective study shows
results of the first prospective study of the subject revealed.
The main message for health care workers is, “if you’ve had COVID, at least in the short term, you are unlikely to get it again,” David Eyre, DPhil, senior author, associate professor at the Big Data Institute and infectious diseases clinician at the University of Oxford (England), said in an interview.
Dr. Eyre and colleagues assessed for the presence of two antibodies to SARS-CoV-2 among 12,541 health care workers in the United Kingdom, including about 10% who had a history of polymerase chain reaction (PCR)–confirmed infection. Of those, 223 who did not have antibodies tested positive on PCR for the virus during 31 weeks of follow-up; two participants who did not have antibodies at baseline tested positive.
The study was published online Dec. 23 in The New England Journal of Medicine.
“It’s great news because there have been so many questions regarding whether or not you can be protected against reinfection, and this health care worker study is really an elegant way to address that question,” Mark Slifka, PhD, said in an interview when asked to comment on the findings.
Although “there are millions of people in the U.S. who have been infected with COVID, we don’t know how common reinfection is,” said Dr. Slifka, a researcher at the Oregon National Primate Research Center and professor at Oregon Health & Science University, Portland.
The likelihood of a subsequent positive PCR test result was 1.09 per 10,000 days at risk among those without antibodies, compared with 0.13 per 10,000 days among those with anti-spike antibodies.
The investigators also assessed for the presence of anti–nucleocapsid IgG antibody titers. They found a significant trend for increasing PCR-positive test results with increasing antibody levels. As with the anti-spike antibody findings, 226 of 11,543 health care providers who did not have anti–nucleocapsid IgG antibodies subsequently tested positive on PCR; by contrast, two of 1,172 participants who did not have antibodies tested positive. Adjusted for age, sex, and calendar time, this finding translates to a 0.11 incidence rate ratio (0.13 per 10,000 days at risk; 95% confidence interval, 0.03-0.45; P = .002).
“This is a study a number of us have been trying to do,” said Christopher L. King, MD, PhD, professor of pathology and associate professor of medicine at Case Western Reserve University, Cleveland.
“To really follow a group like this longitudinally like they’ve done, with a large population, and to see such a big difference – it really confirms our suspicion that those who do become infected and develop an antibody response are significantly protected from reinfection.
“What’s great about this study is it’s nearly a 10-fold reduction in risk if you’ve recovered from COVID and have antibodies,” said Dr. King, who was not involved with the research. “That’s what a lot of us have been wanting to know.”
Unanswered questions remain
“How long this immunity lasts, we don’t know,” Dr. King said. He predicted that antibody protection could last a year to a year and a half. The duration of protection could vary. “We know some people lose their antibodies pretty quickly, and other people don’t,” he said.
Dr. Slifka said the suggestion of “a substantially reduced risk for at least 6 months ... is great news, and the timing couldn’t be better, because we’re rolling out the vaccines.”
Not all antibody responses are alike. For example, data indicate that antibody levels following immunization with the Pfizer/BioNTech or Moderna vaccines are higher on average than those of people who’ve had a natural infection, Dr. King said. He added that initial data on the AstraZeneca COVID-19 vaccine in development showed lower antibody levels compared with natural immunity.
The Centers for Disease Control and Prevention recommends immunization for those with a history of infection. “People who have gotten sick with COVID-19 may still benefit from getting vaccinated,” the CDC notes on its Facts About COVID-19 Vaccines website. “Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before,” the CDC stated.
The agency also notes that people appear to become susceptible to reinfection approximately 90 days after onset of infection. However, the new evidence from the UK study that persons have up to 6 months of immune protection might lead to a modification of recommendations, especially at a time when vaccine supplies are limited, Dr. Slifka said.
Another unanswered question is why the two study participants with antibodies subsequently tested positive for reinfection. “There are a lot of things that could have made these people more susceptible,” Dr. King said. For example, they could have been heavily exposed to SARS-CoV-2 or been immunocompromised for another reason.
Furthermore, the immune response involves more than antibody levels, Dr. King noted. Research in rhesus monkeys suggests that T cells play a role, but not as prominent a part as antibodies. “What I think is protecting us from infection is primarily the antibodies, although the T cells are probably important. Once you get infected, the T cells are probably playing a more important role in terms of whether you get very sick or not,” he said.
Multiplication + addition = more protected?
The 90% natural immunity protection in the study approaches the 95% efficacy associated with the Pfizer and Moderna vaccines, Dr. Slifka noted. Even without immunization, this could mean a portion of the U.S. population is already protected against future infection.
Furthermore, the CDC estimates that there are about 7.7 cases of COVID-19 for every case reported.
As of Sept. 30, the CDC reported that there were 6,891,764 confirmed cases. The agency estimated that overall, approximately 53 million people in the United States have been infected. More recent numbers from Johns Hopkins University’s Coronavirus Resource Center indicate that there were 18.2 million cases in the United States as of Dec. 22. If that tally is multiplied by 7.7, the total number protected could approach 140 million, Dr. Slifka said.
“That could really be a boost in terms of knocking this pandemic down in the next couple of months,” Dr. Slifka said.
“Now, if we were to modify the current recommendations and briefly defer vaccination of people with confirmed cases of COVID-19 until later on, we could start reaching herd immunity pretty quickly,” he added.
Real-life implications
“There is no such thing as 100% protection, even from the infection itself. So when you’re dealing with someone with possible exposure to COVID-19, you still need to follow the proper precautions,” Dr. Slifka said.
Nonetheless, he said, “This is great news for those on the front lines who are wondering whether or not they would have any protection if they had COVID-19 before. And the answer is yes – there is a very good chance they will have protection, based on this quite large study.”
One limitation of the study is that the population consisted predominantly of healthy adult health care workers aged 65 years or younger. “Further studies are needed to assess postinfection immunity in other populations, including children, older adults, and persons with coexisting conditions, including immunosuppression,” the researchers noted.
Dr. Eyre plans to continue following the health care workers in the study, some of whom have been vaccinated for COVID-19. This ongoing research will allow him and coinvestigators to “confirm the protection offered by vaccination and investigate how postvaccine antibody responses vary by whether you have had COVID-19 before or not. We also want to understand more about how long postinfection immunity lasts.”
Dr. Eyre has received grants as a Robinson Foundation Fellow and NIHR Oxford BRC senior fellow during the conduct of the study. Dr. Slifka and Dr. King report no relevant financial relationships.

Another unanswered question is why the two study participants with antibodies subsequently tested positive for reinfection. “There are a lot of things that could have made these people more susceptible,” Dr. King said. For example, they could have been heavily exposed to SARS-CoV-2 or been immunocompromised for another reason.
Furthermore, the immune response involves more than antibody levels, Dr. King noted. Research in rhesus monkeys suggests that T cells play a role, but not as prominent a part as antibodies. “What I think is protecting us from infection is primarily the antibodies, although the T cells are probably important. Once you get infected, the T cells are probably playing a more important role in terms of whether you get very sick or not,” he said.
Multiplication + addition = more protected?
The 90% natural immunity protection in the study approaches the 95% efficacy associated with the Pfizer and Moderna vaccines, Dr. Slifka noted. Even without immunization, this could mean a portion of the U.S. population is already protected against future infection.
Furthermore, the CDC estimates that there are about 7.7 cases of COVID-19 for every case reported.
As of Sept. 30, the CDC reported that there were 6,891,764 confirmed cases. The agency estimated that overall, approximately 53 million people in the United States have been infected. More recent numbers from Johns Hopkins University’s Coronavirus Resource Center indicate that there were 18.2 million cases in the United States as of Dec. 22. If that tally is multiplied by 7.7, the total number protected could approach 140 million, Dr. Slifka said.
“That could really be a boost in terms of knocking this pandemic down in the next couple of months,” Dr. Slifka said.
“Now, if we were to modify the current recommendations and briefly defer vaccination of people with confirmed cases of COVID-19 until later on, we could start reaching herd immunity pretty quickly,” he added.
Real-life implications
“There is no such thing as 100% protection, even from the infection itself. So when you’re dealing with someone with possible exposure to COVID-19, you still need to follow the proper precautions,” Dr. Slifka said.
Nonetheless, he said, “This is great news for those on the front lines who are wondering whether or not they would have any protection if they had COVID-19 before. And the answer is yes – there is a very good chance they will have protection, based on this quite large study.”
One limitation of the study is that the population consisted predominantly of healthy adult health care workers aged 65 years or younger. “Further studies are needed to assess postinfection immunity in other populations, including children, older adults, and persons with coexisting conditions, including immunosuppression,” the researchers noted.
Dr. Eyre plans to continue following the health care workers in the study, some of whom have been vaccinated for COVID-19. This ongoing research will allow him and coinvestigators to “confirm the protection offered by vaccination and investigate how postvaccine antibody responses vary by whether you have had COVID-19 before or not. We also want to understand more about how long postinfection immunity lasts.”

results of the first prospective study of the subject revealed.
The main message for health care workers is, “if you’ve had COVID, at least in the short term, you are unlikely to get it again,” David Eyre, DPhil, senior author, associate professor at the Big Data Institute and infectious diseases clinician at the University of Oxford (England), said in an interview.
Dr. Eyre and colleagues assessed for the presence of two antibodies to SARS-CoV-2 among 12,541 health care workers in the United Kingdom, including about 10% who had a history of polymerase chain reaction (PCR)–confirmed infection. Of those, 223 who did not have antibodies tested positive on PCR for the virus during 31 weeks of follow-up; two participants who did not have antibodies at baseline tested positive.
The study was published online Dec. 23 in The New England Journal of Medicine.
“It’s great news because there have been so many questions regarding whether or not you can be protected against reinfection, and this health care worker study is really an elegant way to address that question,” Mark Slifka, PhD, said in an interview when asked to comment on the findings.
Although “there are millions of people in the U.S. who have been infected with COVID, we don’t know how common reinfection is,” said Dr. Slifka, a researcher at the Oregon National Primate Research Center and professor at Oregon Health & Science University, Portland.
The likelihood of a subsequent positive PCR test result was 1.09 per 10,000 days at risk among those without antibodies, compared with 0.13 per 10,000 days among those with anti-spike antibodies.
The investigators also assessed for the presence of anti–nucleocapsid IgG antibody titers. They found a significant trend for increasing PCR-positive test results with increasing antibody levels. As with the anti-spike antibody findings, 226 of 11,543 health care providers who did not have anti–nucleocapsid IgG antibodies subsequently tested positive on PCR; by contrast, two of 1,172 participants who did not have antibodies tested positive. Adjusted for age, sex, and calendar time, this finding translates to a 0.11 incidence rate ratio (0.13 per 10,000 days at risk; 95% confidence interval, 0.03-0.45; P = .002).
“This is a study a number of us have been trying to do,” said Christopher L. King, MD, PhD, professor of pathology and associate professor of medicine at Case Western Reserve University, Cleveland.
“To really follow a group like this longitudinally like they’ve done, with a large population, and to see such a big difference – it really confirms our suspicion that those who do become infected and develop an antibody response are significantly protected from reinfection.
“What’s great about this study is it’s nearly a 10-fold reduction in risk if you’ve recovered from COVID and have antibodies,” said Dr. King, who was not involved with the research. “That’s what a lot of us have been wanting to know.”
Unanswered questions remain
“How long this immunity lasts, we don’t know,” Dr. King said. He predicted that antibody protection could last a year to a year and a half. The duration of protection could vary. “We know some people lose their antibodies pretty quickly, and other people don’t,” he said.
Dr. Slifka said the suggestion of “a substantially reduced risk for at least 6 months ... is great news, and the timing couldn’t be better, because we’re rolling out the vaccines.”
Not all antibody responses are alike. For example, data indicate that antibody levels following immunization with the Pfizer/BioNTech or Moderna vaccines are higher on average than those of people who’ve had a natural infection, Dr. King said. He added that initial data on the AstraZeneca COVID-19 vaccine in development showed lower antibody levels compared with natural immunity.
The Centers for Disease Control and Prevention recommends immunization for those with a history of infection. “People who have gotten sick with COVID-19 may still benefit from getting vaccinated,” the CDC notes on its Facts About COVID-19 Vaccines website. “Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before,” the CDC stated.
The agency also notes that people appear to become susceptible to reinfection approximately 90 days after onset of infection. However, the new evidence from the UK study that persons have up to 6 months of immune protection might lead to a modification of recommendations, especially at a time when vaccine supplies are limited, Dr. Slifka said.

Moderna’s COVID-19 vaccine deemed ‘highly effective,’ but further studies needed
The Food and Drug Administration’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) evaluated
The panel acknowledged that further studies will be required post issuance of an Emergency Use Authorization (EUA) to collect additional data on the safety and effectiveness of the vaccine. A briefing document released by the FDA on Dec. 17, 2020, summarized interim results and included recommendations from VRBPAC on use of Moderna’s mRNA-1273 COVID-19 vaccine.
“On November 30, 2020, ModernaTX (the Sponsor) submitted an EUA request to FDA for an investigational COVID-19 vaccine (mRNA-1273) intended to prevent COVID-19,” the committee wrote.
The mRNA-1273 vaccine trial
Among 30,351 individuals aged 18 years and older, the efficacy, safety, and immunogenicity of the mRNA-1273 vaccine candidate was evaluated in a randomized, stratified, observer-blind, placebo-controlled phase 3 study. Participants were randomly assigned (1:1) to receive two injections of either 100 mcg of mRNA-1273 (n = 15,181) or saline placebo (n = 15,170) administered intramuscularly on day 1 and day 29.
The primary efficacy endpoint was efficacy of mRNA-1273 against PCR-confirmed COVID-19 with onset at least 14 days following the second dose. The primary safety endpoint was to characterize the safety of the vaccine following one or two doses.
Efficacy
Among 27,817 subjects included in the first interim analysis (data cutoff: Nov. 7, 2020), 5 cases of COVID-19 with onset at least 14 days after the second dose occurred among vaccine recipients and 90 case occurred among placebo recipients, corresponding to 94.5% vaccine efficacy (95% confidence interval, 86.5%-97.8%).
“Subgroup analyses of the primary efficacy endpoint showed similar efficacy point estimates across age groups, genders, racial and ethnic groups, and participants with medical comorbidities associated with high risk of severe COVID-19,” they reported.
Data from the final scheduled analysis of the primary efficacy endpoint (data cutoff: Nov. 21, 2020; median follow-up of >2 months after dose 2), demonstrated 94.1% vaccine efficacy (95% confidence interval, 89.3%-96.8%), corresponding to 11 cases of COVID-19 in the vaccine group and 185 cases in the placebo group.
When stratified by age, the vaccine efficacy was 95.6% (95% CI, 90.6%-97.9%) for individuals 18-64 years of age and 86.4% (95% CI, 61.4%-95.5%) for those 65 years of age or older.
In addition, results from secondary analyses indicated benefit for mRNA-1273 in preventing severe COVID-19 cases, COVID-19 in those with prior SARS-CoV-2 infection, and infection after the first dose, but these data were not conclusive.
Safety
Among 30,350 subjects included in the first interim analysis (data cutoff: Nov. 11, 2020; median follow-up of 7 weeks post second dose), no specific safety concerns were observed that would prevent issuance of an EUA.
Additional safety data (data cutoff: Nov. 25, 2020; median follow-up of 9 weeks post second dose) were provided on Dec. 7, 2020, but did not change the conclusions from the first interim analysis.
The most common vaccine-related adverse reactions were injection site pain (91.6%), fatigue (68.5%), headache (63.0%), muscle pain (59.6%), joint pain (44.8%), and chills (43.4%).
“The frequency of serious adverse events (SAEs) was low (1.0% in the mRNA-1273 arm and 1.0% in the placebo arm), without meaningful imbalances between study arms,” they reported.
Myocardial infarction (0.03%), nephrolithiasis (0.02%), and cholecystitis (0.02%) were the most common SAEs that were numerically greater in the vaccine arm than the placebo arm; however, the small number of cases does not infer a casual relationship.
“The 2-dose vaccination regimen was highly effective in preventing PCR-confirmed COVID-19 occurring at least 14 days after receipt of the second dose,” the committee wrote. “[However], it is critical to continue to gather data about the vaccine even after it is made available under EUA.”
The associated phase 3 study was sponsored by ModernaTX.
