Babies better protected from COVID if mother vaccinated during pregnancy: study
In a first of its kind study, researchers found women who received two mRNA COVID vaccine doses during pregnancy were 61% less likely to have a baby hospitalized for COVID-19 during the first 6 months of life.
In addition, two doses of the Pfizer/BioNTech or Moderna COVID vaccine later in a pregnancy were linked to an even higher level of protection, 80%, compared with 32% when given before 20 weeks’ gestation.
This finding suggests a greater transfer of maternal antibodies closer to birth, but more research is needed, cautioned senior study author Manish Patel, MD, during a Tuesday media telebriefing held by the Centers for Disease Control and Prevention.
Unanswered questions include how the babies got infected or if there is any protection afforded to babies for women vaccinated before pregnancy.
“We cannot be sure about the source of the infection,” said Dr. Patel, a medical epidemiologist with the CDC COVID-19 Emergency Response Team.
Dana Meaney-Delman, MD, MPH, agreed, but added that “perinatal transmission of the virus is very rare” with SARS-CoV-2. She is a practicing obstetrician and gynecologist and chief of the CDC Infant Outcomes Monitoring Research and Prevention Branch.
The study numbers were too small to show if a booster shot during pregnancy or breastfeeding could provide even greater protection for babies, Dr. Patel said.
The early release study was published online Feb. 15 in the CDC’s Morbidity and Mortality Weekly Report (MMWR).
Many previous studies looking at COVID-19 immunization during pregnancy focused on maternal health and “have clearly shown that receiving an mRNA COVID-19 vaccine during pregnancy reduces the risk for severe illness,” Dr. Meaney-Delman said.
Some dual protection suggested
Now there is evidence for a potential benefit to babies as well when a pregnant woman gets vaccinated. The study “provides real-world evidence that getting COVID-19 vaccination during pregnancy might help protect infants less than 6 months [of age],” Dr. Meaney-Delman said.
“These findings continue to emphasize the importance of COVID-19 vaccination during pregnancy to protect people who are pregnant and also to protect their babies,” she said.
Dr. Patel and colleagues studied 379 infants younger than 6 months hospitalized between July 1, 2021 and Jan. 17 of this year. Delta and then the Omicron variant predominated during this time.
The infants were admitted to one of 20 children’s hospitals in 17 states. The researchers compared 176 infants admitted with a positive COVID-19 PCR test to another 203 infants with a negative PCR test who served as controls.
Half as many mothers of infants admitted with COVID-19 were vaccinated during pregnancy, 16%, versus 32% of mothers of the control infants.
Vaccination with two doses of mRNA vaccine during pregnancy was 61% effective (95% confidence interval, 31%-78%) at preventing hospitalization among these infants. Because the study was epidemiological, the lower risk was an association, not a cause-and-effect finding, Dr. Patel said.
Babies admitted to the hospital positive for COVID-19 were more likely to be non-Hispanic Black, 18%, versus 9% of control group babies; and more likely to be Hispanic, 34% versus 28%, respectively.
A total 24% of infants with COVID-19 were admitted to the ICU, including the baby of an unvaccinated mother who required extracorporeal membrane oxygenation (ECMO). Another baby of an unvaccinated mother was the only infant death during the study.
Maternal vaccination trends
A reporter pointed out that COVID-19 vaccination rates tend to be low among pregnant women. “So there is some exciting news,” Dr. Meaney-Delman said, referring to a steady increase in the percentages of pregnant women in the U.S. choosing to get vaccinated, according to the CDC Data Tracker website.
“The numbers are encouraging, [but] they’re not quite where we need them to be, and they do differ by race and ethnicity,” she added.

CDC preparing to update mask guidance
“As we consider future metrics, which will be updated soon, we recognize the importance of not just cases … but critically, medically severe disease that leads to hospitalizations,” Dr. Walensky said at a White House news briefing. “We must consider hospital capacity as an additional important barometer.”
She later added, “We are looking at an overview of much of our guidance, and masking in all settings will be a part of that.”
Coronavirus cases continue to drop nationwide. This week’s 7-day daily average of cases is 147,000, a decrease of 40%. Hospitalizations have dropped 28% to 9,500, and daily deaths are 2,200, a decrease of 9%.
“Omicron cases are declining, and we are all cautiously optimistic about the trajectory we’re on,” Dr. Walensky said. “Things are moving in the right direction, but we want to remain vigilant to do all we can so this trajectory continues.”
Dr. Walensky said public masking remains especially important if someone is symptomatic or not feeling well, or if there has been a COVID-19 exposure. Those who are within 10 days of being diagnosed with the virus should also remain masked in public.
“We all share the same goal: to get to a point where COVID-19 is no longer disrupting our daily lives. A time when it won’t be a constant crisis,” Dr. Walensky said. “Moving from this pandemic will be a process led by science and epidemiological trends, and one that relies on the powerful tools we already have.”

Stroke risk is highest right after COVID infection
, new research shows.
The study among Medicare beneficiaries with COVID-19 also showed that stroke risk is higher for relatively young older adults, those aged 65 to 74 years, and those without a history of stroke.
The study highlights the impact COVID-19 has on the cardiovascular system, said study author Quanhe Yang, PhD, senior scientist, Division for Heart Disease and Stroke Prevention, Centers for Disease Control and Prevention, Atlanta.
“Clinicians and patients should understand that stroke might be one of the very important clinical consequences of COVID-19.”
The study was presented during the hybrid International Stroke Conference held in New Orleans and online. The meeting was presented by the American Stroke Association, a division of the American Heart Association.
Stroke is the fifth leading cause of death in the U.S. As an increasing number of people become infected with COVID-19, “it’s important to determine if there’s a relationship between COVID and the risk of stroke,” said Dr. Yang.
Findings from prior research examining the link between stroke and COVID-19 have been inconsistent, he noted. Some studies found an association while others did not, and in still others, the association was not as strong as expected.
Many factors may contribute to these inconsistent findings, said Dr. Yang, including differences in study design, inclusion criteria, comparison groups, sample sizes, and countries where the research was carried out. Dr. Yang pointed out that many of these studies were done in the early stages of the pandemic or didn’t include older adults, the population most at risk for stroke.
The current study included 19,553 Medicare beneficiaries aged 65 years and older diagnosed with COVID-19 and hospitalized with acute ischemic stroke. The median age at diagnosis of COVID-19 was 80.5 years, 57.5% were women, and more than 75% were non-Hispanic Whites.
To ensure the stroke occurred after a COVID infection, researchers used a self-controlled case series study design, a “within person” comparison between the risk period and the control period.
They divided the study period (Jan. 1, 2019 to Feb. 28, 2021) into the exposure or stroke risk periods after the COVID diagnosis (0-3 days; 4-7 days; 8-15 days; and 15-28 days) and control periods.
Strokes that occurred 7 days before or 28 days after a COVID diagnosis served as a control period. “Any stroke that occurred outside the risk window is in the control period,” explained Dr. Yang.
He added that the control period provides a baseline. “Without COVID-19, this is what I would expect” in terms of the number of strokes.
To estimate the incidence rate ratio (IRR), investigators compared the incidence of acute ischemic stroke in the various risk periods with control periods.
The IRR was 10.97 (95% confidence interval, 10.30-11.68) at 0-3 days. The risk then quickly declined but stayed higher than the control period. The IRRs were: 1.59 (95% CI, 1.35-1.87) at 4-7 days; 1.23 (95% CI, 1.07-1.41) at 8-14 days; and 1.06 (95% CI, 0.95-1.18) at 15-28 days.
The temporary increase in stroke risk early after an infection isn’t novel; the pattern has been observed with influenza, respiratory infections, and shingles, said Dr. Yang. “But COVID-19 appears to be particularly risky.”
Although the mechanism driving the early increased stroke risk isn’t fully understood, it’s likely tied to an “exaggerated inflammatory response,” said Dr. Yang. This can trigger the cascade of events setting the stage for a stroke – a hypercoagulation state leading to the formation of blood clots that then block arteries to the brain, he said.
It’s also possible the infection directly affects endothelial cells, leading to rupture of plaque, again blocking arteries and raising stroke risks, added Dr. Yang.
The association was stronger among younger beneficiaries, aged 65 to 74 years, compared with those 85 years and older, a finding Dr. Yang said was somewhat surprising. But he noted other studies have found stroke patients with COVID are younger than stroke patients without COVID – by some 5 to 6 years.
“If COVID-19 disproportionately affects younger patients, that may explain the stronger association,” said Dr. Yang. “Stroke risk increases tremendously with age, so if you’re a younger age, your baseline stroke risk is lower.”
The association was also stronger among beneficiaries without a history of stroke. Again, this could be related to the stronger association among younger patients who are less likely to have suffered a stroke. The association was largely consistent across sex and race/ethnicities.
Dr. Yang stressed that the findings need to be confirmed with further studies.
The study was carried out before widespread use of vaccinations in the U.S. Once those data are available, Dr. Yang and his colleagues plan to determine if vaccinations modify the association between COVID-19 and stroke risk.
The new results contribute to the mounting evidence that a COVID-19 infection “can actually affect multiple human organs structurally or functionally in addition to the impact on [the] respiratory system,” said Dr. Yang.
Some dates of COVID-19 diagnoses may be incorrect due to limited test availability, particularly early in the pandemic. Another limitation of the study was possible misclassification from the use of Medicare real-time preliminary claims.
In a provided statement, Louise D. McCullough, MD, PhD, chair of the ISC 2022 and professor and chair of neurology, McGovern Medical School, University of Texas Health Science Center at Houston, noted that the study focused on older adults because it was examining Medicare beneficiaries.
“But everyone is likely at risk for stroke after COVID,” she said. “Any infection is linked to stroke risk, probably because any infection will cause inflammation, and inflammation can cause clots or thrombus, which is the cause of stroke.”
There was no outside funding for the study. No relevant conflicts of interest were disclosed.

Medical boards pressured to let it slide when doctors spread COVID misinformation
Tennessee’s Board of Medical Examiners unanimously adopted in September 2021 a statement that said doctors spreading COVID misinformation – such as suggesting that vaccines contain microchips – could jeopardize their license to practice.
“I’m very glad that we’re taking this step,” Dr. Stephen Loyd, MD, the panel’s vice president, said at the time. “If you’re spreading this willful misinformation, for me it’s going to be really hard to do anything other than put you on probation or take your license for a year. There has to be a message sent for this. It’s not okay.”
The board’s statement was posted on a government website.
The growing tension in Tennessee between conservative lawmakers and the state’s medical board may be the most prominent example in the country. But the Federation of State Medical Boards, which created the language adopted by at least 15 state boards, is tracking legislation introduced by Republicans in at least 14 states that would restrict a medical board’s authority to discipline doctors for their advice on COVID.
Humayun Chaudhry, DO, the federation’s CEO, called it “an unwelcome trend.” The nonprofit association, based in Euless, Tex., said the statement is merely a COVID-specific restatement of an existing rule: that doctors who engage in behavior that puts patients at risk could face disciplinary action.
Although doctors have leeway to decide which treatments to provide, the medical boards that oversee them have broad authority over licensing. Often, doctors are investigated for violating guidelines on prescribing high-powered drugs. But physicians are sometimes punished for other “unprofessional conduct.” In 2013, Tennessee’s board fined U.S. Rep. Scott DesJarlais for separately having sexual relations with two female patients more than a decade earlier.
Still, stopping doctors from sharing unsound medical advice has proved challenging. Even defining misinformation has been difficult. And during the pandemic, resistance from some state legislatures is complicating the effort.
A relatively small group of physicians peddle COVID misinformation, but many of them associate with America’s Frontline Doctors. Its founder, Simone Gold, MD, has claimed patients are dying from COVID treatments, not the virus itself. Sherri Tenpenny, DO, said in a legislative hearing in Ohio that the COVID vaccine could magnetize patients. Stella Immanuel, MD, has pushed hydroxychloroquine as a COVID cure in Texas, although clinical trials showed that it had no benefit. None of them agreed to requests for comment.
The Texas Medical Board fined Dr. Immanuel $500 for not informing a patient of the risks associated with using hydroxychloroquine as an off-label COVID treatment.
In Tennessee, state lawmakers called a special legislative session in October to address COVID restrictions, and Republican Gov. Bill Lee signed a sweeping package of bills that push back against pandemic rules. One included language directed at the medical board’s recent COVID policy statement, making it more difficult for the panel to investigate complaints about physicians’ advice on COVID vaccines or treatments.
In November, Republican state Rep. John Ragan sent the medical board a letter demanding that the statement be deleted from the state’s website. Rep. Ragan leads a legislative panel that had raised the prospect of defunding the state’s health department over its promotion of COVID vaccines to teens.
Among his demands, Rep. Ragan listed 20 questions he wanted the medical board to answer in writing, including why the misinformation “policy” was proposed nearly two years into the pandemic, which scholars would determine what constitutes misinformation, and how was the “policy” not an infringement on the doctor-patient relationship.
“If you fail to act promptly, your organization will be required to appear before the Joint Government Operations Committee to explain your inaction,” Rep. Ragan wrote in the letter, obtained by Kaiser Health News and Nashville Public Radio.
In response to a request for comment, Rep. Ragan said that “any executive agency, including Board of Medical Examiners, that refuses to follow the law is subject to dissolution.”
He set a deadline of Dec. 7.
In Florida, a Republican-sponsored bill making its way through the state legislature proposes to ban medical boards from revoking or threatening to revoke doctors’ licenses for what they say unless “direct physical harm” of a patient occurred. If the publicized complaint can’t be proved, the board could owe a doctor up to $1.5 million in damages.
Although Florida’s medical board has not adopted the Federation of State Medical Boards’ COVID misinformation statement, the panel has considered misinformation complaints against physicians, including the state’s surgeon general, Joseph Ladapo, MD, PhD.
Dr. Chaudhry said he’s surprised just how many COVID-related complaints are being filed across the country. Often, boards do not publicize investigations before a violation of ethics or standards is confirmed. But in response to a survey by the federation in late 2021, two-thirds of state boards reported an increase in misinformation complaints. And the federation said 12 boards had taken action against a licensed physician.
“At the end of the day, if a physician who is licensed engages in activity that causes harm, the state medical boards are the ones that historically have been set up to look into the situation and make a judgment about what happened or didn’t happen,” Dr. Chaudhry said. “And if you start to chip away at that, it becomes a slippery slope.”
The Georgia Composite Medical Board adopted a version of the federation’s misinformation guidance in early November and has been receiving 10-20 complaints each month, said Debi Dalton, MD, the chairperson. Two months in, no one had been sanctioned.
Dr. Dalton said that even putting out a misinformation policy leaves some “gray” area. Generally, physicians are expected to follow the “consensus,” rather than “the newest information that pops up on social media,” she said.
“We expect physicians to think ethically, professionally, and with the safety of patients in mind,” Dr. Dalton said.
A few physician groups are resisting attempts to root out misinformation, including the Association of American Physicians and Surgeons, known for its stands against government regulation.
Some medical boards have opted against taking a public stand against misinformation.
The Alabama Board of Medical Examiners discussed signing on to the federation’s statement, according to the minutes from an October meeting. But after debating the potential legal ramifications in a private executive session, the board opted not to act.
In Tennessee, the Board of Medical Examiners met on the day Rep. Ragan had set as the deadline and voted to remove the misinformation statement from its website to avoid being called into a legislative hearing. But then, in late January, the board decided to stick with the policy – although it did not republish the statement online immediately – and more specifically defined misinformation, calling it “content that is false, inaccurate or misleading, even if spread unintentionally.”
Board members acknowledged they would likely get more pushback from lawmakers but said they wanted to protect their profession from interference.
“Doctors who are putting forth good evidence-based medicine deserve the protection of this board so they can actually say: ‘Hey, I’m in line with this guideline, and this is a source of truth,’” said Melanie Blake, MD, the board’s president. “We should be a source of truth.”
The medical board was looking into nearly 30 open complaints related to COVID when its misinformation statement came down from its website. As of early February, no Tennessee physician had faced disciplinary action.

New study shows natural immunity to COVID has enduring strength
It’s a matter of quality, not quantity. That’s the gist of a new Israeli study that shows that unvaccinated people with a prior SARS-CoV-2 infection create antibodies that are more effective in the long run compared with others who were vaccinated but never infected.
“While the quantity of antibodies decreases with time in both COVID-19 recovered patients and vaccinated individuals,
This difference could explain why previously infected patients appear to be better protected against a new infection than those who have only been vaccinated, according to a news release attached to the research.
One key caveat: This research does not include people from the later part of the pandemic.
This means there is a catch in terms of timing, William Schaffner, MD, Vanderbilt University School of Medicine, Nashville, Tenn., said when asked to comment on the study: “The study involved only the early COVID strains – it has no information on either the Delta or Omicron variants. Thus, the results primarily are of scientific or historical interest but are not immediately relevant to the current situation.”
The findings come from an early release of a study to be presented at the European Congress of Clinical Microbiology & Infectious Diseases in April.
An unexpected finding of the study showed that obese people had better protection – a higher and more sustained immune response – compared with overweight and normal-weight individuals.
“The results in the obese group were indeed unexpected and need further research to confirm or dispute,” Dr. Schaffner said. “Obesity does predispose to more severe disease.”
A focus on earlier strains
Dr. Cohen – a senior research assistant in infectious disease prevention at the Sheba Medical Center in Ramat Gan, Israel – and her colleagues recruited participants between March 25, 2020 and Nov. 25, 2020 and completed analysis in April 2021. This means they assessed people with a history of infection from the original, the Alpha, and some Beta strains of SARS-CoV-2.
Dr. Cohen indicated that the next phase of their research will examine innate and acquired immune responses to the more recent Delta and Omicron variants.
The investigators analyzed the antibody-induced immune response up to 1 year in 130 COVID-19 recovered but unvaccinated individuals versus up to 8 months among 402 others matched by age and body mass index (BMI) and without previous infection who received two doses of the Pfizer vaccine.
The numbers of antibodies a month after vaccination were higher than those in the COVID-19 recovered patients. However, these numbers also declined more steeply in the vaccinated group, they note.
To assess the antibody performance, the investigators used the avidity index. This assay measures antibody function based on the strength of the interactions between the antibody and the viral antigen.
They found that the avidity index was higher in vaccinated individuals than in recovered patients initially but changes over time. At up to 6 months, the index did not significantly change in vaccinated individuals, whereas it gradually increased in recovered patients. This increase would potentially protect them from reinfection, the authors note.
These findings stand in stark contrast to an Oct. 29, 2021, Centers for Disease Control and Prevention study that found that COVID-19 vaccines provided five times the protection of natural immunity.
Those results, published in the organization’s Morbidity and Mortality Weekly Report, suggest that vaccination helps people mount a higher, stronger, and more consistent level of immunity against COVID-19 hospitalization than infection alone for at least 6 months.
Protection linked to obesity
Another finding that ran against the scientific grain was the data about obesity.
There was a higher and more persistent antibody performance among people with a BMI of 30 kg/m2.
This could relate to greater disease severity and/or a more pronounced initial response to infection among the obese group.
“Our hypothesis is that patients with obesity begin with a more pronounced response – reflected also by the disease manifestation – and the trend of decline is similar, therefore the kinetics of immune response remain higher throughout the study,” Dr. Cohen said.
“The results in the obese group were indeed unexpected and need further research to confirm or dispute,” said Dr. Schaffner, who is also the current medical director of the National Foundation for Infectious Diseases. “Obesity does predispose to more severe disease.”
Before the boosters
Along with using participants from only the earlier part of the pandemic, another limitation of the study was that the vaccinated group had only two doses of vaccine; boosters were not given during the time of the study, Dr. Schaffner said.
“Again, not the current situation.”
“That said, the strength and duration of natural immunity provided by the early variants was solid for up to a year, confirming previous reports,” he said.

Along with using participants from only the earlier part of the pandemic, another limitation of the study was that the vaccinated group had only two doses of vaccine; boosters were not given during the time of the study, Dr. Schaffner said.
“Again, not the current situation.”
“That said, the strength and duration of natural immunity provided by the early variants was solid for up to a year, confirming previous reports,” he said.

Children and COVID: Weekly cases down by more than half
A third consecutive week of declines in new COVID-19 cases among children has brought the weekly count down by 74% since the Omicron surge peaked in mid-January, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.
weekly COVID report. They also noted that the weekly tally was still higher than anything seen during the Delta surge.
The total number of pediatric cases was over 12.3 million as of Feb. 10, with children representing 18.9% of cases in all ages, according to the AAP/CHA report. The Centers for Disease Control and Prevention puts the two measures at 10.4 million and 17.3% on its COVID Data Tracker, based on availability of age data for 59.6 million total cases as of Feb. 14. The CDC also reported that 1,282 children have died from COVID-19 so far, which is about 0.17% of all deaths with age data available.
The AAP and CHA have been collecting data from state and territorial health departments, which have not always been consistently available over the course of the pandemic. Also, the CDC defines children as those under age 18 years, but that upper boundary varies from 14 to 20 among the states.
The decline of the Omicron variant also can be seen in new admissions of children with confirmed COVID-19, which continued to drop. The 7-day average of 435 admissions per day for the week of Feb. 6-12 was less than half of the peak seen in mid-January, when it reached 914 per day. The daily admission rate on Feb. 12 was 0.60 per 100,000 children aged 0-17 years – again, less than half the peak rate of 1.25 reported on Jan. 16, CDC data show.
The fading threat of Omicron also seems to be reflected in recent vaccination trends. Both initial doses and completions declined for the fourth consecutive week (Feb. 3-9) among children aged 5-11 years, while initiations held steady for 12- to 17-year-olds but completions declined for the third straight week, the AAP said in its separate vaccination report, which is based on data from the CDC.
As of Feb. 14, almost 32% of children aged 5-11 – that’s almost 9.2 million individuals – had received at least one dose of the COVID-19 vaccine and just over 24% (6.9 million) were fully vaccinated, the CDC reported. For children aged 12-17, the corresponding figures are 67% (16.9 million) and 57% (14.4 million). Newly available data from the CDC also indicate that 19.5% (2.8 million) of children aged 12-17 have received a booster dose.

Long COVID symptoms linked to effects on vagus nerve
Several long COVID symptoms could be linked to the effects of the coronavirus on a vital central nerve, according to new research being released in the spring.
The vagus nerve, which runs from the brain into the body, connects to the heart, lungs, intestines, and several muscles involved with swallowing. It plays a role in several body functions that control heart rate, speech, the gag reflex, sweating, and digestion.
Those with long COVID and vagus nerve problems could face long-term issues with their voice, a hard time swallowing, dizziness, a high heart rate, low blood pressure, and diarrhea, the study authors found.
Their findings will be presented at the 2022 European Congress of Clinical Microbiology and Infectious Diseases in late April.
“Most long COVID subjects with vagus nerve dysfunction symptoms had a range of significant, clinically relevant, structural and/or functional alterations in their vagus nerve, including nerve thickening, trouble swallowing, and symptoms of impaired breathing,” the study authors wrote. “Our findings so far thus point at vagus nerve dysfunction as a central pathophysiological feature of long COVID.”
Researchers from the University Hospital Germans Trias i Pujol in Barcelona performed a study to look at vagus nerve functioning in long COVID patients. Among 348 patients, about 66% had at least one symptom that suggested vagus nerve dysfunction. The researchers did a broad evaluation with imaging and functional tests for 22 patients in the university’s Long COVID Clinic from March to June 2021.
Of the 22 patients, 20 were women, and the median age was 44. The most frequent symptoms related to vagus nerve dysfunction were diarrhea (73%), high heart rates (59%), dizziness (45%), swallowing problems (45%), voice problems (45%), and low blood pressure (14%).
Almost all (19 of 22 patients) had three or more symptoms related to vagus nerve dysfunction. The average length of symptoms was 14 months.
Of 22 patients, 6 had a change in the vagus nerve in the neck, which the researchers observed by ultrasound. They had a thickening of the vagus nerve and increased “echogenicity,” which suggests inflammation.
What’s more, 10 of 22 patients had flattened “diaphragmatic curves” during a thoracic ultrasound, which means the diaphragm doesn’t move as well as it should during breathing, and abnormal breathing. In another assessment, 10 of 16 patients had lower maximum inspiration pressures, suggesting a weakness in breathing muscles.
Eating and digestion were also impaired in some patients, with 13 reporting trouble with swallowing. During a gastric and bowel function assessment, eight patients couldn’t move food from the esophagus to the stomach as well as they should, while nine patients had acid reflux. Three patients had a hiatal hernia, which happens when the upper part of the stomach bulges through the diaphragm into the chest cavity.
The voices of some patients changed as well. Eight patients had an abnormal voice handicap index 30 test, which is a standard way to measure voice function. Among those, seven patients had dysphonia, or persistent voice problems.
The study is ongoing, and the research team is continuing to recruit patients to study the links between long COVID and the vagus nerve. The full paper isn’t yet available, and the research hasn’t yet been peer reviewed.
“The study appears to add to a growing collection of data suggesting at least some of the symptoms of long COVID is mediated through a direct impact on the nervous system,” David Strain, MD, a clinical senior lecturer at the University of Exeter (England), told the Science Media Centre.
“Establishing vagal nerve damage is useful information, as there are recognized, albeit not perfect, treatments for other causes of vagal nerve dysfunction that may be extrapolated to be beneficial for people with this type of long COVID,” he said.

Blind optimism only works in fantasy football. Time to get realistic
In the age of COVID, what exactly does it mean to be optimistic? I get this question quite a bit from virtually everyone I meet in one form or another through my work with the George Washington Resiliency and Well-Being Center in Washington, D.C. Giving a lecture on resilience and staying positive can be a significant challenge. Especially when we wake up to the news that 1 of every 100 older Americans has died secondary to COVID. The mind doesn’t really know how to process this type of loss. It is hard to maintain any form of a positive attitude when you’re still struggling just to accept the magnitude of what humanity has experienced over the past 2 years.
In “Resilience: The Science of Mastering Life’s Greatest Challenges,” (Cambridge, England: Cambridge University Press, 2018), Steven M. Southwick, MD, and Dennis S. Charney, MD, identify 10 critical factors associated with very resilient individuals. The authors based their work on science, personal experience, and interviews of people who have literally been through hell and back. One of the critical factors they identified is optimism.
“Optimism ignites resilience, providing energy to power the other resilience factors. It facilitates an active and creative approach to coping with challenging situations.”
Dr. Southwick and Dr. Charney are a lot smarter than me and far more patient to weave all this data together into a coherent story about optimism. Sounds like a damn good factor to focus a lecture on in my book! Slight problem: In my experience, many health professionals are already expert optimists. They literally eat, sleep, and sincerely breathe this stuff. So if we are going to talk about optimism, then we need to discuss realistic optimism.
How does realistic optimism differ from, say, blind optimism? Dr. Southwick and Dr. Charney’s review of the literature points to three features worthy of highlighting.
Realistic vs. blind optimism: Take-home points
- In realistic optimism, we notice the negative but don’t stay engaged with it. Realistic optimists moved on from problems that were not solvable.
- Blind optimism can lead to underestimating risk, overestimating abilities, and inadequate preparation.
Growing up in northeast Ohio, I can absolutely embrace the concept of realistic optimism. It’s overcast in Cleveland 8 months out of the year. To hope for 3 sunny days in a row in April is genuinely a fools’ errand. So you learn over time, the sun will shine; you just have to at times wait 3-4 months for it to occur.
From a skill perspective, realistic optimism could be conceptualized as a great mix of radical acceptance, emotion regulation, and focused problem solving. This is all fine, but to be realistically optimistic, we must first stop wishing for a better tomorrow. You may say, I don’t wish for or see rainbows and unicorns, et cetera, et cetera. Okay, so you don’t verbalize your wishes, but on a small level, you may engage in wishful thinking. Here are a few wishful thoughts that I would daydream about, which were not realistically optimistic at various points:
- “Once we get enough COVID-19 tests, things will improve.”
- “All we need to do is get vaccines, and then the new normal is right there.”
- “Once everyone gets the booster, then we got this thing beat.”
At this point, you could argue that I was engaged in blind optimism. I consider the above statements blind for a couple of reasons. They weren’t balanced (both positive and negative), didn’t have a clear definition of the outcome, and were more focused on external events I couldn’t control. These statements were the equivalent of wishes, and I don’t have a magic lamp with a genie, so I need to let go of my wishful thinking first. Let me rephrase that: I need to forcefully toss it into the sea of COVID variants and start figuring out how I’m going to tread water for another 6-12 months. So with this in mind, here are my initial thoughts on ways to navigate the next year of the pandemic:
- A multilayered form of protection gives me the best chance to survive the next 6 months of the pandemic.
- It will take time, but I’ll process the loss associated with a workplace that will never be the same.
- Until we have positivity test rates lower than 2% across the globe, COVID will remain a substantial disruption to humanity.
- I can’t bring back missed graduation or the first day of school, but I can share ways that I’ve countered and survived loneliness in my life with my children.
Okay, this is the starting point – hopefully not pessimistic, or blindly optimistic, just realistic. Now I can address other important topics, such as planning to rebuild my disappointing fantasy football team. I was No. 1 in our GW department of psychiatry fantasy football league until my star running back Derrick Henry went down. My residents will become attendings and still give me grief about this for many years to follow, and that is a very good thing.
Everyone be well and safe.

Estrogen supplementation may reduce COVID-19 death risk
Estrogen supplementation is associated with a reduced risk of death from COVID-19 among postmenopausal women, new research suggests.
The findings, from a nationwide study using data from Sweden, were published online Feb. 14 in BMJ Open by Malin Sund, MD, PhD, of Umeå (Sweden) University Faculty of Medicine and colleagues.
Among postmenopausal women aged 50-80 years with verified COVID-19, those receiving estrogen as part of hormone replacement therapy for menopausal symptoms were less than half as likely to die from it as those not receiving estrogen, even after adjustment for confounders.
“This study shows an association between estrogen levels and COVID-19 death. Consequently, drugs increasing estrogen levels may have a role in therapeutic efforts to alleviate COVID-19 severity in postmenopausal women and could be studied in randomized control trials,” the investigators write.
However, coauthor Anne-Marie Fors Connolly, MD, PhD, a resident in clinical microbiology at Umeå University, cautioned: “This is an observational study. Further clinical studies are needed to verify these results before recommending clinicians to consider estrogen supplementation.”
Stephen Evans, professor of pharmacoepidemiology, London School of Hygiene & Tropical Medicine, agrees.
He told the U.K. Science and Media Centre: “This is an observational study comparing three groups of women based on whether they used hormonal therapy to boost estrogen levels or who had, as a result of treatment for breast cancer ... reduced estrogen levels or neither. The findings are apparently dramatic.”
“At the very least, great caution should be exercised in thinking that menopausal hormone therapy will have substantial, or even any, benefits in dealing with COVID-19,” he warned.
Do women die less frequently from COVID-19 than men?
Studies conducted early in the pandemic suggest women may be protected from poor outcomes of SARS-CoV-2 infection, compared with men, even after adjustment for confounders.
According to more recent data from the Swedish Public Health Agency, of the 16,501 people who have died from COVID-19 since the start of the pandemic, about 45% are women and 55% are men. About 70% who have received intensive care because of COVID-19 are men, although cumulative data suggest that women are nearly as likely to die from COVID-19 as men, Dr. Connolly told this news organization.
For the current study, a total of 14,685 women aged 50-80 years were included, of whom 17.3% (2,535) had received estrogen supplementation, 81.2% (11,923) had native estrogen levels with no breast cancer or estrogen supplementation (controls), and 1.5% (227) had decreased estrogen levels because of breast cancer and antiestrogen treatment.
The group with decreased estrogen levels had a more than twofold risk of dying from COVID-19 compared with controls (odds ratio, 2.35), but this difference was no longer significant after adjustments for potential confounders including age, income, and educational level, and weighted Charlson Comorbidity Index (wCCI).
However, the group with augmented estrogen levels had a decreased risk of dying from COVID-19 before (odds ratio, 0.45) and after (OR, 0.47) adjustment.
The percentages of patients who died of COVID-19 were 4.6% of controls, 10.1% of those with decreased estrogen, and 2.1% with increased estrogen.
Not surprisingly, the risk of dying from COVID-19 also increased with age (OR of 1.15 for every year increase in age) and comorbidities (OR, 1.13 per increase in wCCI). Low income and having only a primary level education also increased the odds of dying from COVID-19.
Data on obesity, a known risk factor for COVID-19 death, weren’t reported.
“Obesity would have been a very relevant variable to include. Unfortunately, this information is not present in the nationwide registry data that we used for our study,” Dr. Connolly told this news organization.
While the data are observational and can’t be used to inform treatment, Dr. Connolly pointed to a U.S. randomized clinical trial currently recruiting patients that will investigate the effect of estradiol and progesterone therapy in 120 adults hospitalized with COVID-19.
In the meantime, she warned doctors and patients: “Please do not consider ending antiestrogen treatment following breast cancer – this is a necessary treatment for the cancer.”
Dr. Evans noted, “There are short-term benefits of menopausal hormone therapy but women should not, based on this or other observational studies, be advised to take HRT [hormone replacement therapy] for a supposed benefit on death from COVID-19.”
The study had several nonpharmaceutical industry funders, including Umeå University and the Knut and Alice Wallenberg Foundation. The authors and Dr. Evans have reported no relevant financial relationships.

FROM BMJ OPEN
Can cancer patients get approved COVID therapies?
In mid-November, Kevin Billingsley, MD, MBA, chief medical officer at Yale Cancer Center, New Haven, Conn., was keeping a close eye on the new COVID variant sweeping across South Africa. Six weeks later, the Omicron variant had become the dominant strain in the U.S. – and the Yale health system was no exception.
“As we entered January, we had a breathtaking rate of infection in our hospital,” said Dr. Billingsley, who also leads clinical care at the Smilow Cancer Hospital. “Some of the newly authorized COVID agents were available but not widely enough to make a clinically meaningful impact to protect all high-risk individuals during this surge.”
That left the team at Yale with difficult decisions about who would receive these treatments and who wouldn’t.
The health system convened a COVID-19 immunocompromised working group to identify which patients should get priority access to one of the promising drugs authorized to treat the infection – the monoclonal antibody sotrovimab and antiviral pills Paxlovid and molnupiravir – or the sole available option to prevent it, Evusheld.
“Although clinically sound, none of these decisions have been easy,” Dr. Billingsley told this news organization. “We have done a lot of case-by-case reviewing and a lot of handwringing. Omicron has been a wild ride for us all, and we have been doing the best we can with limited resources.”
‘We’re seeing incredible variability’
The team at Yale is not alone. The restricted supply of COVID-19 treatments has led many oncologists and other experts across the U.S. to create carefully curated lists of their most vulnerable patients.
In late December, the National Institutes of Health published broad criteria to help clinicians prioritize patients most likely to benefit from these therapies. A handful of state health departments, including those in Michigan and Minnesota, established their own standards. Patients with cancer – specifically those with hematologic malignancies and receiving oncology therapies that compromise the immune system – appeared at the top of everyone’s list.
But ultimately individual decisions about who receives these drugs and how they’re allocated fell to institutions.
“Overall, what we’re seeing is incredible variability across the country, because there’s no uniform agreement on what comprises best practices on allocating scarce resources,” said Matthew Wynia, MD, MPH, professor of medicine and director of the Center for Bioethics and Humanities at the University of Colorado, Aurora. “There are so many people at the top of most lists, and the drugs are in such short supply, that there’s no guarantee even those in the top tier will get it.”
This news organization spoke to experts across the country about their experiences accessing these treatments during the Omicron surge and their strategies prioritizing patients with cancer.
Dealing with limited supply
Overall, the limited supply of COVID-19 drugs means not every patient who’s eligible to receive a treatment will get one.
A snapshot of the past 2 weeks, for instance, shows that the count of new infections hit almost 4.3 million, while distribution of the two antiviral pills Paxlovid and molnupiravir and the monoclonal antibody sotrovimab reached just over 600,000 courses.
Since receiving emergency use authorization in early December, almost 500,000 courses of the pre-exposure prophylactic agent Evusheld – which offers about 6 months of protection for immunocompromised individuals – have been distributed; however, about 7 million adults in the U.S. could potentially benefit from it.
In addition, the distribution of drugs is uneven. The federal government manages the overall distribution to states, but states then decide how to divvy up these allocations to hospitals, pharmacies, and medical centers. In Ohio, for instance, the antivirals go to providers who already receive monoclonal antibodies, while in Tennessee, the supply of antiviral agents only goes to Walmart pharmacies.
This strategy, Dr. Wynia explained, can leave clinicians at the mercy of where and how much states decide to allocate to each location. “I’ve heard of some hospitals and health systems in Colorado that aren’t using all they’ve got, but most don’t have nearly enough,” Dr. Wynia said. However, he noted, “some of that is inevitable. We will never get a perfect distribution of these drugs when there is such variable need and demand.”
And, according to Nicolette Louissaint, PhD, MBA, senior vice president of policy and strategic planning at the Healthcare Distribution Alliance in Arlington, Virginia, “we can take some comfort that the federal government is actively looking at cases from week to week and working with state and local health departments to see who needs these products, which means the process is constantly being reviewed and adjusted.”
Plus, not every positive COVID-19 case, even among immunocompromised individuals, necessarily warrants treatment. “If, for instance, an individual with cancer has a mild case of COVID-19, their provider may not deem it necessary for them to receive treatment,” Dr. Louissaint noted.
Still, given the limited and unpredictable supply, “we have had to be thoughtful about who gets these drugs,” said Derek Raghavan, MD, PhD, president of the Levine Cancer Institute, part of the 40-hospital Atrium Health system in Charlotte, North Carolina.
Dr. Raghavan said the highest priority goes to patients with hematologic malignancies, those receiving or coming off chemotherapy or experiencing myelosuppression and immune paresis, as well as those who have undergone organ transplants. Age and other comorbidities, such as diabetes or obesity, play into the lineup as well.
To further hone their priority list, the Levine Cancer Institute has implemented a cancer-centered Hospital at Home initiative. The program includes 40 oncology nurse navigators who routinely screen and score all cancer patients who test positive for COVID-19 by their symptoms and risk factors. For a time-sensitive treatment like Paxlovid, this close monitoring allows patients with COVID to access the pills within 5 days of symptom onset.
Ultimately, “the decision regarding who gets these drugs is [made] by a team to overcome any risk of personal bias, and some of it just comes down to the interface between clinical judgment and available data,” Dr. Raghavan told this news organization. “Although we’d like to have more COVID drugs available and fewer patients with COVID, we have been able to get adequate supplies for our most at-risk patients.”
Like Dr. Raghavan, Karen Bloch, MD, MPH, the medical director for the COVID Infusion Clinic at Vanderbilt University Medical Center (VUMC), said the clinic has had to be highly selective about which patients would benefit most from the COVID monoclonal antibodies. For patients with cancer, her team prioritizes individuals who would be least able to develop antibodies through vaccination or natural infection – which includes patients with B cell malignancies, acute myeloid leukemia, or multiple myeloma receiving active treatment, as well as those who recently received an allogeneic or autologous stem cell transplant.
“Since our criteria for treatment with therapies such as sotrovimab and Evusheld are pretty stringent, we have had sufficient supply to treat those who meet our internal ‘category 1’ predetermined criteria,” said Dr. Bloch, professor of medicine and associate division director for clinical affairs at VUMC, Nashville. “More recently, as the supply chain has begun to open up, we’ve been able to loosen our criteria for sotrovimab, though not for Evusheld yet.”
The Yale team described a similar evolution. “Initially, only a small subset of oncology patients could get these drugs,” said Osama (Sam) Abdelghany, PharmD, MHA, associate director of Oncology Pharmacy Services at Smilow Cancer Hospital. But as the caseload has diminished, Dr. Abdelghany noted, “we have been able to reach many more patients with COVID-19.”
An equitable system?
Dr. Wynia, who has written many reports on crisis standards of care, has spent thousands of hours delving into the ethics of allocating scarce resources during a disaster.
A core problem arises when there are too many people who need a scarce resource and no way of differentiating among them.
In response to the limited supply of COVID-19 treatments, some institutions, such as the University of Pittsburgh Medical Center and Massachusetts General Hospital, have created a lottery system. Others, such as Johns Hopkins Medicine, have opted for first come, first served. Each strategy comes with caveats.
“First come, first served prioritization may be quicker, but it gives more well-resourced people an advantage and lends itself to people abusing the system or exacerbating existing disparities,” Dr. Wynia said.
While a lottery system may be more equitable, this strategy often comes at the price of efficiency. “The practicality of doing a lottery when you have to make a decision about whether or not to treat the patient sitting in front of you comes with its own challenges,” Dr. Wynia said.
At the University of Colorado, he explained, the health center constantly scans medical records for patients who have been diagnosed with COVID and fall into a high-risk group. That way clinicians can call or email those most likely to benefit from these drugs.
“It ends up being a bit of a first come, first served strategy,” Dr. Wynia said. “But we also do not have a huge supply coming in each week, so reaching out to the most eligible people when we have the drugs in hand means more privileged patients are less likely to game the system.”
To manage the supply of Evusheld, Timothy Kubal, MD, MBA, and colleagues also reach out to patients most likely to benefit – specifically, those who can’t mount an adequate antibody response after vaccination.
“We screen all of our patients who have been receiving anti-CD20 agents and other chemotherapy agents known to suppress antibody response,” Dr. Kubal, a medical oncologist/hematologist at the Moffitt Institute in Tampa, Florida, said in an interview. “We then test those patients for antibodies and deliver Evusheld if they have no evidence of antibodies.”
Fortunately, in the coming months, distribution of these drugs should improve significantly. Pfizer says it expects to deliver 10 million courses of Paxlovid by the end of June, and another 10 million by the end of September. More than 1 million courses of sotrovimab should be distributed by GlaxoSmithKline through the end of March. And, recently, the Biden administration announced it purchased 1.2 million courses of Evusheld from AstraZeneca.
“Every few weeks, because the COVID picture changes, the demand changes,” said Dr. Louissaint. “With vaccination rates going up and cases going down, fewer patients will need these products.”
Still, the constant barrage of supply shortages over the past 2 years – from COVID tests, ventilators, and personal protective equipment early on to COVID vaccines a year later and more recently health care staff and COVID tests once again – has taken its toll.
“We have faced supply challenge after challenge and have had to be creative in each situation,” said Lisa Barbarotta, MSN, APRN, program director of Oncology Education and Clinical Practice at Smilow Cancer Hospital. “Nothing has been easy about this.”
And, Dr. Bloch cautioned, even with broader access to COVID-19 drugs on the horizon, there is still no substitute for vaccination. “Getting vaccinated is the best and first line of defense for most people,” she said.

To manage the supply of Evusheld, Timothy Kubal, MD, MBA, and colleagues also reach out to patients most likely to benefit – specifically, those who can’t mount an adequate antibody response after vaccination.
“We screen all of our patients who have been receiving anti-CD20 agents and other chemotherapy agents known to suppress antibody response,” Dr. Kubal, a medical oncologist/hematologist at the Moffitt Institute in Tampa, Florida, said in an interview. “We then test those patients for antibodies and deliver Evusheld if they have no evidence of antibodies.”
Fortunately, in the coming months, distribution of these drugs should improve significantly. Pfizer says it expects to deliver 10 million courses of Paxlovid by the end of June, and another 10 million by the end of September. More than 1 million courses of sotrovimab should be distributed by GlaxoSmithKline through the end of March. And, recently, the Biden administration announced it purchased 1.2 million courses of Evusheld from AstraZeneca.
“Every few weeks, because the COVID picture changes, the demand changes,” said Dr. Louissaint. “With vaccination rates going up and cases going down, fewer patients will need these products.”
Still, the constant barrage of supply shortages over the past 2 years – from COVID tests, ventilators, and personal protective equipment early on to COVID vaccines a year later and more recently health care staff and COVID tests once again – has taken its toll.
“We have faced supply challenge after challenge and have had to be creative in each situation,” said Lisa Barbarotta, MSN, APRN, program director of Oncology Education and Clinical Practice at Smilow Cancer Hospital. “Nothing has been easy about this.”
And, Dr. Bloch cautioned, even with broader access to COVID-19 drugs on the horizon, there is still no substitute for vaccination. “Getting vaccinated is the best and first line of defense for most people,” she said.

In mid-November, Kevin Billingsley, MD, MBA, chief medical officer at Yale Cancer Center, New Haven, Conn., was keeping a close eye on the new COVID variant sweeping across South Africa. Six weeks later, the Omicron variant had become the dominant strain in the U.S. – and the Yale health system was no exception.
“As we entered January, we had a breathtaking rate of infection in our hospital,” said Dr. Billingsley, who also leads clinical care at the Smilow Cancer Hospital. “Some of the newly authorized COVID agents were available but not widely enough to make a clinically meaningful impact to protect all high-risk individuals during this surge.”
That left the team at Yale with difficult decisions about who would receive these treatments and who wouldn’t.
The health system convened a COVID-19 immunocompromised working group to identify which patients should get priority access to one of the promising drugs authorized to treat the infection – the monoclonal antibody sotrovimab and antiviral pills Paxlovid and molnupiravir – or the sole available option to prevent it, Evusheld.
“Although clinically sound, none of these decisions have been easy,” Dr. Billingsley told this news organization. “We have done a lot of case-by-case reviewing and a lot of handwringing. Omicron has been a wild ride for us all, and we have been doing the best we can with limited resources.”
‘We’re seeing incredible variability’
The team at Yale is not alone. The restricted supply of COVID-19 treatments has led many oncologists and other experts across the U.S. to create carefully curated lists of their most vulnerable patients.
In late December, the National Institutes of Health published broad criteria to help clinicians prioritize patients most likely to benefit from these therapies. A handful of state health departments, including those in Michigan and Minnesota, established their own standards. Patients with cancer – specifically those with hematologic malignancies and receiving oncology therapies that compromise the immune system – appeared at the top of everyone’s list.
But ultimately individual decisions about who receives these drugs and how they’re allocated fell to institutions.
“Overall, what we’re seeing is incredible variability across the country, because there’s no uniform agreement on what comprises best practices on allocating scarce resources,” said Matthew Wynia, MD, MPH, professor of medicine and director of the Center for Bioethics and Humanities at the University of Colorado, Aurora. “There are so many people at the top of most lists, and the drugs are in such short supply, that there’s no guarantee even those in the top tier will get it.”
This news organization spoke to experts across the country about their experiences accessing these treatments during the Omicron surge and their strategies prioritizing patients with cancer.
Dealing with limited supply
Overall, the limited supply of COVID-19 drugs means not every patient who’s eligible to receive a treatment will get one.
A snapshot of the past 2 weeks, for instance, shows that the count of new infections hit almost 4.3 million, while distribution of the two antiviral pills Paxlovid and molnupiravir and the monoclonal antibody sotrovimab reached just over 600,000 courses.
Since receiving emergency use authorization in early December, almost 500,000 courses of the pre-exposure prophylactic agent Evusheld – which offers about 6 months of protection for immunocompromised individuals – have been distributed; however, about 7 million adults in the U.S. could potentially benefit from it.
In addition, the distribution of drugs is uneven. The federal government manages the overall distribution to states, but states then decide how to divvy up these allocations to hospitals, pharmacies, and medical centers. In Ohio, for instance, the antivirals go to providers who already receive monoclonal antibodies, while in Tennessee, the supply of antiviral agents only goes to Walmart pharmacies.
This strategy, Dr. Wynia explained, can leave clinicians at the mercy of where and how much states decide to allocate to each location. “I’ve heard of some hospitals and health systems in Colorado that aren’t using all they’ve got, but most don’t have nearly enough,” Dr. Wynia said. However, he noted, “some of that is inevitable. We will never get a perfect distribution of these drugs when there is such variable need and demand.”
And, according to Nicolette Louissaint, PhD, MBA, senior vice president of policy and strategic planning at the Healthcare Distribution Alliance in Arlington, Virginia, “we can take some comfort that the federal government is actively looking at cases from week to week and working with state and local health departments to see who needs these products, which means the process is constantly being reviewed and adjusted.”
Plus, not every positive COVID-19 case, even among immunocompromised individuals, necessarily warrants treatment. “If, for instance, an individual with cancer has a mild case of COVID-19, their provider may not deem it necessary for them to receive treatment,” Dr. Louissaint noted.
Still, given the limited and unpredictable supply, “we have had to be thoughtful about who gets these drugs,” said Derek Raghavan, MD, PhD, president of the Levine Cancer Institute, part of the 40-hospital Atrium Health system in Charlotte, North Carolina.
Dr. Raghavan said the highest priority goes to patients with hematologic malignancies, those receiving or coming off chemotherapy or experiencing myelosuppression and immune paresis, as well as those who have undergone organ transplants. Age and other comorbidities, such as diabetes or obesity, play into the lineup as well.
To further hone their priority list, the Levine Cancer Institute has implemented a cancer-centered Hospital at Home initiative. The program includes 40 oncology nurse navigators who routinely screen and score all cancer patients who test positive for COVID-19 by their symptoms and risk factors. For a time-sensitive treatment like Paxlovid, this close monitoring allows patients with COVID to access the pills within 5 days of symptom onset.
Ultimately, “the decision regarding who gets these drugs is [made] by a team to overcome any risk of personal bias, and some of it just comes down to the interface between clinical judgment and available data,” Dr. Raghavan told this news organization. “Although we’d like to have more COVID drugs available and fewer patients with COVID, we have been able to get adequate supplies for our most at-risk patients.”
Like Dr. Raghavan, Karen Bloch, MD, MPH, the medical director for the COVID Infusion Clinic at Vanderbilt University Medical Center (VUMC), said the clinic has had to be highly selective about which patients would benefit most from the COVID monoclonal antibodies. For patients with cancer, her team prioritizes individuals who would be least able to develop antibodies through vaccination or natural infection – which includes patients with B cell malignancies, acute myeloid leukemia, or multiple myeloma receiving active treatment, as well as those who recently received an allogeneic or autologous stem cell transplant.
“Since our criteria for treatment with therapies such as sotrovimab and Evusheld are pretty stringent, we have had sufficient supply to treat those who meet our internal ‘category 1’ predetermined criteria,” said Dr. Bloch, professor of medicine and associate division director for clinical affairs at VUMC, Nashville. “More recently, as the supply chain has begun to open up, we’ve been able to loosen our criteria for sotrovimab, though not for Evusheld yet.”
The Yale team described a similar evolution. “Initially, only a small subset of oncology patients could get these drugs,” said Osama (Sam) Abdelghany, PharmD, MHA, associate director of Oncology Pharmacy Services at Smilow Cancer Hospital. But as the caseload has diminished, Dr. Abdelghany noted, “we have been able to reach many more patients with COVID-19.”
An equitable system?
Dr. Wynia, who has written many reports on crisis standards of care, has spent thousands of hours delving into the ethics of allocating scarce resources during a disaster.
A core problem arises when there are too many people who need a scarce resource and no way of differentiating among them.
In response to the limited supply of COVID-19 treatments, some institutions, such as the University of Pittsburgh Medical Center and Massachusetts General Hospital, have created a lottery system. Others, such as Johns Hopkins Medicine, have opted for first come, first served. Each strategy comes with caveats.
“First come, first served prioritization may be quicker, but it gives more well-resourced people an advantage and lends itself to people abusing the system or exacerbating existing disparities,” Dr. Wynia said.
While a lottery system may be more equitable, this strategy often comes at the price of efficiency. “The practicality of doing a lottery when you have to make a decision about whether or not to treat the patient sitting in front of you comes with its own challenges,” Dr. Wynia said.
At the University of Colorado, he explained, the health center constantly scans medical records for patients who have been diagnosed with COVID and fall into a high-risk group. That way clinicians can call or email those most likely to benefit from these drugs.
“It ends up being a bit of a first come, first served strategy,” Dr. Wynia said. “But we also do not have a huge supply coming in each week, so reaching out to the most eligible people when we have the drugs in hand means more privileged patients are less likely to game the system.”
