The Food and Drug Administration on May 10 granted emergency use authorization (EUA) for the Pfizer coronavirus vaccine to be given to children 12-15 years old.  

The much-expected decision increases the likelihood that schools in the United States will fully reopen in the fall – a goal of both the Biden and Trump administrations.

Acting FDA Commissioner Janet Woodcock, MD, called the decision “a significant step” in “returning to a sense of normalcy.”

“Today’s action allows for a younger population to be protected from COVID-19, bringing us closer to returning to a sense of normalcy and to ending the pandemic,” she said in a statement. “Parents and guardians can rest assured that the agency undertook a rigorous and thorough review of all available data, as we have with all of our COVID-19 vaccine emergency use authorizations.”

The Pfizer adolescent vaccine is not yet a done deal, though.

Next, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will decide on May 12 whether to recommend use of the vaccine in this age group. After that, CDC Director Rochelle Walensky, MD, will decide whether to give the green light for the vaccine to be administered to that age group.

The FDA action on May 10 amends the Dec. 11, 2020, emergency use authorization that allowed the Pfizer vaccine to be given to people 16 and older. Pfizer was the first company to receive an EUA for its adult vaccine and is the first to receive authorization for its adolescent vaccine. Pfizer is conducting clinical trials on much younger children, too.

The Moderna and Johnson & Johnson vaccines are authorized for people 18 and up. Moderna also has launched clinical trials in children.

Most health experts have said the United States needs to vaccinate children before the COVID-19 pandemic can truly be brought under control. The 12- to 15-year-old group represents 17 million people, about 5% of the population. Thus far, 58% of U.S. adults have had at least one dose of a vaccine and 34.8% of all Americans are fully vaccinated.

American Academy of Pediatrics President Lee Savio Beers, MD, praised the agency’s decision, calling it a “critically important step in bringing life-saving vaccines to children and adolescents. Our youngest generations have shouldered heavy burdens over the past year, and the vaccine is a hopeful sign that they will be able to begin to experience all the activities that are so important for their health and development.”

President Joe Biden recently announced a new strategy for expanding vaccinations in which vaccinating 12- to 15-year-olds was a key component. He said the administration was ready to ship the adolescent vaccine directly to pharmacies and pediatricians to speed up the vaccination rate.

In March, Anthony S. Fauci, MD, told a Senate committee, “We don’t really know what that magical point of herd immunity is, but we do know that if we get the overwhelming population vaccinated, we’re going to be in good shape. … We ultimately would like to get and have to get children into that mix.” 

Pfizer submitted data to the FDA in late March showing its mRNA vaccine was 100% effective at preventing COVID-19 infection in children ages 12-15 in clinical trials.

Though most children have milder symptoms when infected with the coronavirus, about 1.5 million cases in children aged 11-17 were reported to the CDC between March 1, 2020, and April 30 of this year, the FDA news release said.

Albert Bourla, CEO of Pfizer, tweeted that “today brings very encouraging news for families and adolescents across the United States.

“While this is a meaningful step forward, we are still in a critical period of combating #COVID19 around the world. In the coming weeks, we hope to continue to receive authorizations from global regulators to support worldwide vaccination efforts,” he said. 

“It’s essential for children to be vaccinated against COVID-19. According to data compiled by the AAP and Children’s Hospital Association, more than 3.8 million children have tested positive for COVID-19 in the United States since the start of the pandemic,” said Dr. Savio Beers. “While fewer children than adults have suffered the most severe disease, this is not a benign disease in children. Thousands of children have been hospitalized, and hundreds have died. We will soon have a very safe, highly effective vaccine that can prevent so much suffering. I encourage parents to talk with their pediatricians about how to get the vaccine for their adolescents as soon as they are eligible.”

Single breath diffusion capacity for carbon monoxide shows greater decline over time in COPD patients compared with controls, but declines significantly more in women compared with men, according to data from 602 adults with a history of smoking.

In previous studies, diffusion capacity for carbon monoxide (DLco) has been associated with decreased exercise capacity and poor health status in patients with COPD, but its association as a measure of disease progression has not been well studied, wrote Ciro Casanova, MD, of Hospital Universitario La Candelaria, Spain, and colleagues.

In a study published in the journal CHEST^®, the researchers identified 506 adult smokers with COPD and 96 adult smoker controls without COPD. Lung function based on single breath DLco was measured each year for 5 years. The study population was part of the COPH History Assessment in SpaiN (CHAIN), an ongoing observational study of adults with COPD. COPD was defined as a history of at least 10 pack-years of smoking and a post-bronchodilator FEV₁/FVC greater than 0.7 after 400 micrograms of albuterol, the researchers said.

During the 5-year period, the average overall annual decline in DLco was 1.34% in COPD patients, compared with .04% in non-COPD controls (P = .004). Among COPD patients, age, body mass index, FEV₁%, and active smoking were not associated with longitudinal change in DLco values, the researchers said.

Notably, women with COPD at baseline had lower baseline DLco values compared with men (11.37%) and a significantly steeper decline in DLco (.89%) compared with men (P = .039). “Being a woman was the only factor that related to the annual rate of change in DLco,” the researchers said.

In a subgroup analysis, the researchers identified 305 COPD patients and 69 non-COPD controls who had at least 3 DLco measurements over the 5-year study period. In this group, 16.4% patients with COPD and 4.3% smokers without COPD showed significant yearly declines in DLco of –4.139% and –4.440%, respectively. Among COPD patients, significantly more women than men showed significant DLco declines (26% vs. 14%, P = .005). No significant differences were observed in mortality or hospitalizations per patient-year for COPD patients with and without DLco decline, the researchers said.

The study findings were limited by several factors including the lack of annual measurements of DLco among some patients, potential variability in the instruments used to measure DLco, and the absence of computerized tomography data for the chest, the researchers noted. However, the results support the value of the test for COPD progression when conducted at 3- to 4-year intervals, given the slow pace of the decline, they said. More research is needed, but “women seem to have a different susceptibility to cigarette smoke in the alveolar or pulmonary vascular domains,” they added.

DLco remains a valuable marker

The study is important because the usual longitudinal decline of diffusion capacity, an important physiological parameter in patients with COPD, was unknown, Juan P. de Torres, MD, of Queen’s University, Kingston, Ont., said in an interview.

“The finding of a different longitudinal decline of DLco in women was a surprise,” said Dr. de Torres, who was a coauthor on the study. “We knew from previous works from our group that COPD has a different clinical and prognostic behavior in women with COPD, but this specific finding is novel and important,” he said.

“These results provide information about the testing frequency (3-4 years) needed to use DLco as a marker of COPD progression in clinical practice,” Dr. de Torres added.

“What is the driving cause of this sex difference is unknown. We speculate that different causes of low DLco in COPD such as degree of emphysema, interstitial lung abnormalities, and pulmonary hypertension, may have a different prevalence and progression in women with COPD,” he said.

Looking ahead, “Large studies including an adequate sample of women with COPD is urgently needed because they will be the main face of COPD in the near future,” said Dr. de Torres. “Sex difference in their physiological characteristics, the reason to explain those differences and how they behave longitudinally is also urgently needed,” he added. 

The study was supported in part by AstraZeneca and by the COPD research program of the Spanish Respiratory Society. The researchers and Dr. de Torres had no financial conflicts to disclose.

Editor in Chief of this news organization Eric Topol, MD, founder and director of the Scripps Research Translational Institute in La Jolla, Calif., and professor of molecular medicine, has been closely following COVID-19 data since the pandemic began. He spoke with writer Miriam E. Tucker about the latest on SARS-CoV-2 variants and their impact on vaccine efficacy. The conversation serves as a follow-up to his April 13, 2021, New York Times opinion piece, in which he advised readers that “all variants are innocent until proven guilty.”

You have expressed overall confidence in the efficacy of the vaccines thus far despite the emergence of variants, with some caveats. How do you see the current situation?

The Centers for Disease Control and Prevention has designated five “variants of concern,” but only three of them are real concerns – B.1.1.7, first detected in the United Kingdom; P.1, in Brazil and Japan; and B.1.351, in South Africa. Yet, all three are susceptible to our current vaccines.

The U.K. B.1.1.7 is the worst variant of all because it’s hypertransmissible, so I call it a “superspreader strain.” It also causes more severe illness independent of the spread, so it’s a double whammy. It’s clear that it also causes more deaths. The only arguable point is whether it’s 30% or 50% more deaths, but regardless, it’s more lethal and more transmissible.

The B.1.1.7 is going to be the dominant strain worldwide. It could develop new mutations within it that could come back to haunt us. We must keep watch.

But for now, it’s fully responsive to all the vaccines, which is great because if we didn’t have them, we wouldn’t have gotten through this U.S. pandemic like we have, and neither would Israel and the United Kingdom and other countries that have been able to get out of the crisis. We met the enemy and put it in check.

As for the South Africa variant of concern, B.1.351, we just got some encouraging news showing that it›s very responsive to the Pfizer/BioNTech mRNA vaccine in large numbers of people. The study was conducted in Qatar following that country’s mass immunization campaign in which a total of 385,853 people had received at least one vaccine dose and 265,410 had completed the two doses as of March 31, 2021.

At 2 weeks past the second dose, the vaccine was 75% effective at preventing any documented infection with the B.1.351 variant and 89.5% effective against B.1.1.7. The vaccine’s effectiveness against severe, critical, or fatal COVID-19 was greater than 97.4% for all circulating strains in Qatar, where B.1.1.7 and B.1.351 are most prominent.

We also know that B.1.351 is very responsive to the Johnson & Johnson vaccine and the Novavax [vaccine in development] to a lesser degree. It is the most immune-evading variant we’ve seen thus far, with the highest likelihood of providing some vaccine resistance, yet not enough to interfere with vaccination campaigns. So that’s great news.

The caveats here are that you definitely need two doses of the mRNA vaccines to combat the B.1.351 variant. Also, the AstraZeneca vaccine failed to prevent it in South Africa. However, that study was hard to judge because it was underpowered for number of people with mild infections. So, it didn’t look as if it had any efficacy, but maybe it would if tested in a real trial.

The P.1 (Brazil) variant is the second-highest concern after B.1.1.7 because it’s the only one in the United States that’s still headed up. It seems to be competing a bit with B.1.1.7 here. We know it was associated with the crisis in Brazil, in Chile, and some other South American countries. It has some immune escape, but not as bad as B.1.351. It also appears to have somewhat greater transmissibility but not as much as B.1.1.7.

With P.1, we just don’t know enough yet. It was difficult to assess in Brazil because they were in the midst of a catastrophe – like India is now – and you don’t know how much of it is dragged by the catastrophe vs driving it.

We have to respond to P.1 carefully. There are some good data that it does respond to the Chinese vaccine Sinovac and the AstraZeneca vaccine, and it appears to respond to the others as well, based on serum studies. So it doesn’t look like vaccines will be the worry with this variant. Rather, it could be competing with B.1.1.7 and could lead to breakthrough infections in vaccinated people or reinfections in unvaccinated people who had COVID-19. We need several more weeks to sort it out.

Although the B.1.427 and B.1.429 variants initially seen in California remain on the CDC’s concern list, I’m not worried about them.
 

You mentioned the current COVID-19 crisis in India, where a new variant has been described as a “double mutant,” but on Twitter you called it a “scariant.” Why?

First of all, the B.1.617 variant isn’t a double mutant. It has 15 mutations. It’s a stupid term, focusing on two mutations which largely have been put aside as to concern. One of them is the L452R, which is the same as one of the California variants, and that hasn’t proved to be particularly serious or concerning. The other is the 484Q, and it’s not clear whether that has any function.

The B.1.617 is not the driver of the catastrophe in India. It may be contributing a small amount, but it has been overhyped as the double mutant that’s causing it all. Adding to that are what I call “scariant” headlines here in the United States when a few cases of that variant have been seen.

I coined the term scariant in early February because it was a pretty clear trend. People don’t know what variants are. They know a little bit about mutations but not variants, and they’re scared. A few variants are concerning, but we keep learning more and more things to decrease the concern. That’s why I wrote the New York Times op-ed, to try to provide some reassurance, since there’s such paranoia.
 

Do you think booster vaccinations will be necessary? If so, will those be of the original vaccines or new ones that incorporate the variants?

As we go forward, there’s still potential for new variants that we haven’t seen yet that combine the worst of all features – transmissibility and immune evasion – especially since we have a world where COVID-19 is unchecked. So, we’re not out of it yet, but at least for the moment, we have vaccines that are capable of protecting against all variants.

In most people, the immune response against SARS-CoV-2 is very durable and strong and may well last for years. With the most closely related SARS-CoV-1, people still had immune responses up to 18 years later. However, some people will have less robust vaccine responses, including the elderly and the immunocompromised. If they don’t have great responses to the vaccine to start with, over time they’re likely to become more vulnerable, especially if they’re exposed to the variants with some degree of immune evasion.

I think we need to study these individuals post vaccination. A lot of people fit into those categories, including seniors, people being treated for cancer or autoimmune conditions, or post organ transplant. We could set up a prospective study to see whether they develop symptomatic COVID-19 and if so, from what – the original strain, B.1.1.7, or the newer variants.

That’s where I think booster shots may be needed. They may not be necessary across the board, but perhaps just in these special subgroups.

All of the current vaccines can be tweaked to include new variants, but the need for that is uncertain as of now. Moderna is working on a so-called bivalent vaccine that includes the original SARS-CoV-2 strain plus the B.1.351 variant, but it isn’t clear that that’s going to be necessary.

Currently, at least 200 COVID-19 vaccines are in development. There will be vaccines you can inhale, room temperature mRNA vaccines, and potentially even oral vaccines.

In the near future, Novavax is close, and there will likely be a two-dose Johnson & Johnson version that has the same potency as the mRNA vaccines. There are a lot of moving parts here.

There may be a step down in efficacy from mRNA to the others, though, and that shouldn’t be discounted. All of the available vaccines so far protect very well against severe disease and death, but some are less effective against mild to moderate infections, which may then lead to long COVID. We don’t yet know whether those who get mild infection post vaccination can still get long COVID.
 

What do you think it will take to achieve herd immunity?

I prefer the term “containment.” It’s quantitative. If you get to an infection rate of less than 1 in 100,000 people, as they’ve done in Israel, with 0.8 per 100,000, then you have the virus in check, and there will be very little spread when it’s at that controlled rate, with no outbreaks. The United States is currently at about 15 per 100,000. California is at 4. That still has to get lower.

It will be a challenge to get to President Biden’s goal of having 70% of U.S. adults given at least one dose by July 4. We’re now at about 57%. To get that next 13% of adults is going to take an all-out effort: mobile units, going to homes, making it ultraconvenient, education for people with safety concerns, incentivization, and days off.

We also need to get employers, universities, and health systems to get to the mandatory level. We haven’t done that yet. Some universities have mandated it for students, faculty, and staff. We need it in more health care systems. Right now, we only have a couple. We mandate flu shots, and flu is nothing, compared with COVID-19. And the COVID-19 vaccine is far more efficacious – flu shots are 40% efficacious, while these are 95%. COVID-19 is a tenfold more lethal and serious disease, and much more spreadable.

People are using the lack of full licensure by the Food and Drug Administration – as opposed to emergency use authorization – as an excuse not to get vaccinated. A biologics license application takes time to approve. Meanwhile, we have hundreds of millions of doses that have been well tolerated and incredibly effective.

Another aspect to consider regarding containment is that about 110 million Americans have already had COVID-19, even though only about 30 million cases have been confirmed. Most of these people have immune protection, although it’s not as good as if they have one vaccine dose. But they have enough protection to be part of the story here of the wall against COVID-19 and will help us get through this.

That’s a silver lining of having an unchecked epidemic for the entire year of 2020. The good part is that’s helping to get us to achieve an incredible level of containment when we haven’t even been close. Right now, we’re as good as the country has been in the pandemic, but we still have a long gap to get down to that 1 per 100,000. That’s what we should be working toward, and we can get there.

Editor in Chief of this news organization Eric Topol, MD, founder and director of the Scripps Research Translational Institute in La Jolla, Calif., and professor of molecular medicine, has been closely following COVID-19 data since the pandemic began. He spoke with writer Miriam E. Tucker about the latest on SARS-CoV-2 variants and their impact on vaccine efficacy. The conversation serves as a follow-up to his April 13, 2021, New York Times opinion piece, in which he advised readers that “all variants are innocent until proven guilty.”

You have expressed overall confidence in the efficacy of the vaccines thus far despite the emergence of variants, with some caveats. How do you see the current situation?

The Centers for Disease Control and Prevention has designated five “variants of concern,” but only three of them are real concerns – B.1.1.7, first detected in the United Kingdom; P.1, in Brazil and Japan; and B.1.351, in South Africa. Yet, all three are susceptible to our current vaccines.

The U.K. B.1.1.7 is the worst variant of all because it’s hypertransmissible, so I call it a “superspreader strain.” It also causes more severe illness independent of the spread, so it’s a double whammy. It’s clear that it also causes more deaths. The only arguable point is whether it’s 30% or 50% more deaths, but regardless, it’s more lethal and more transmissible.

The B.1.1.7 is going to be the dominant strain worldwide. It could develop new mutations within it that could come back to haunt us. We must keep watch.

But for now, it’s fully responsive to all the vaccines, which is great because if we didn’t have them, we wouldn’t have gotten through this U.S. pandemic like we have, and neither would Israel and the United Kingdom and other countries that have been able to get out of the crisis. We met the enemy and put it in check.

As for the South Africa variant of concern, B.1.351, we just got some encouraging news showing that it›s very responsive to the Pfizer/BioNTech mRNA vaccine in large numbers of people. The study was conducted in Qatar following that country’s mass immunization campaign in which a total of 385,853 people had received at least one vaccine dose and 265,410 had completed the two doses as of March 31, 2021.

At 2 weeks past the second dose, the vaccine was 75% effective at preventing any documented infection with the B.1.351 variant and 89.5% effective against B.1.1.7. The vaccine’s effectiveness against severe, critical, or fatal COVID-19 was greater than 97.4% for all circulating strains in Qatar, where B.1.1.7 and B.1.351 are most prominent.

We also know that B.1.351 is very responsive to the Johnson & Johnson vaccine and the Novavax [vaccine in development] to a lesser degree. It is the most immune-evading variant we’ve seen thus far, with the highest likelihood of providing some vaccine resistance, yet not enough to interfere with vaccination campaigns. So that’s great news.

The caveats here are that you definitely need two doses of the mRNA vaccines to combat the B.1.351 variant. Also, the AstraZeneca vaccine failed to prevent it in South Africa. However, that study was hard to judge because it was underpowered for number of people with mild infections. So, it didn’t look as if it had any efficacy, but maybe it would if tested in a real trial.

The P.1 (Brazil) variant is the second-highest concern after B.1.1.7 because it’s the only one in the United States that’s still headed up. It seems to be competing a bit with B.1.1.7 here. We know it was associated with the crisis in Brazil, in Chile, and some other South American countries. It has some immune escape, but not as bad as B.1.351. It also appears to have somewhat greater transmissibility but not as much as B.1.1.7.

With P.1, we just don’t know enough yet. It was difficult to assess in Brazil because they were in the midst of a catastrophe – like India is now – and you don’t know how much of it is dragged by the catastrophe vs driving it.

We have to respond to P.1 carefully. There are some good data that it does respond to the Chinese vaccine Sinovac and the AstraZeneca vaccine, and it appears to respond to the others as well, based on serum studies. So it doesn’t look like vaccines will be the worry with this variant. Rather, it could be competing with B.1.1.7 and could lead to breakthrough infections in vaccinated people or reinfections in unvaccinated people who had COVID-19. We need several more weeks to sort it out.

Although the B.1.427 and B.1.429 variants initially seen in California remain on the CDC’s concern list, I’m not worried about them.
 

You mentioned the current COVID-19 crisis in India, where a new variant has been described as a “double mutant,” but on Twitter you called it a “scariant.” Why?

First of all, the B.1.617 variant isn’t a double mutant. It has 15 mutations. It’s a stupid term, focusing on two mutations which largely have been put aside as to concern. One of them is the L452R, which is the same as one of the California variants, and that hasn’t proved to be particularly serious or concerning. The other is the 484Q, and it’s not clear whether that has any function.

The B.1.617 is not the driver of the catastrophe in India. It may be contributing a small amount, but it has been overhyped as the double mutant that’s causing it all. Adding to that are what I call “scariant” headlines here in the United States when a few cases of that variant have been seen.

I coined the term scariant in early February because it was a pretty clear trend. People don’t know what variants are. They know a little bit about mutations but not variants, and they’re scared. A few variants are concerning, but we keep learning more and more things to decrease the concern. That’s why I wrote the New York Times op-ed, to try to provide some reassurance, since there’s such paranoia.
 

Do you think booster vaccinations will be necessary? If so, will those be of the original vaccines or new ones that incorporate the variants?

As we go forward, there’s still potential for new variants that we haven’t seen yet that combine the worst of all features – transmissibility and immune evasion – especially since we have a world where COVID-19 is unchecked. So, we’re not out of it yet, but at least for the moment, we have vaccines that are capable of protecting against all variants.

In most people, the immune response against SARS-CoV-2 is very durable and strong and may well last for years. With the most closely related SARS-CoV-1, people still had immune responses up to 18 years later. However, some people will have less robust vaccine responses, including the elderly and the immunocompromised. If they don’t have great responses to the vaccine to start with, over time they’re likely to become more vulnerable, especially if they’re exposed to the variants with some degree of immune evasion.

I think we need to study these individuals post vaccination. A lot of people fit into those categories, including seniors, people being treated for cancer or autoimmune conditions, or post organ transplant. We could set up a prospective study to see whether they develop symptomatic COVID-19 and if so, from what – the original strain, B.1.1.7, or the newer variants.

That’s where I think booster shots may be needed. They may not be necessary across the board, but perhaps just in these special subgroups.

All of the current vaccines can be tweaked to include new variants, but the need for that is uncertain as of now. Moderna is working on a so-called bivalent vaccine that includes the original SARS-CoV-2 strain plus the B.1.351 variant, but it isn’t clear that that’s going to be necessary.

Currently, at least 200 COVID-19 vaccines are in development. There will be vaccines you can inhale, room temperature mRNA vaccines, and potentially even oral vaccines.

In the near future, Novavax is close, and there will likely be a two-dose Johnson & Johnson version that has the same potency as the mRNA vaccines. There are a lot of moving parts here.

The Moderna SARS-CoV-2 vaccine booster developed specifically with variant B.1.351 in mind shows efficacy against that strain and the P1 variant among people already vaccinated for COVID-19, according to first results released May 5.
 

Furthermore, data from the company’s ongoing phase 2 study show the variant-specific booster, known as mRNA-1273.351, achieved higher antibody titers against the B.1.351 variant than did a booster with the original Moderna vaccine.

“We are encouraged by these new data, which reinforce our confidence that our booster strategy should be protective against these newly detected variants. The strong and rapid boost in titers to levels above primary vaccination also clearly demonstrates the ability of mRNA-1273 to induce immune memory,” Stéphane Bancel, chief executive officer of Moderna, said in a statement.

The phase 2 study researchers also are evaluating a multivariant booster that is a 50/50 mix of mRNA-1273.351 and mRNA-1273, the initial vaccine given Food and Drug Administration emergency use authorization, in a single vial.

Unlike the two-dose regimen with the original vaccine, the boosters are administered as a single dose immunization.

The trial participants received a booster 6-8 months after primary vaccination. Titers to the wild-type SARS-CoV-2 virus remained high and detectable in 37 out of 40 participants. However, prior to the booster, titers against the two variants of concern, B.1.351 and P.1, were lower, with about half of participants showing undetectable levels.

In contrast, 2 weeks after a booster with the original vaccine or the B.1.351 strain-specific product, pseudovirus neutralizing titers were boosted in all participants and all variants tested.

“Following [the] boost, geometric mean titers against the wild-type, B.1.351, and P.1 variants increased to levels similar to or higher than the previously reported peak titers against the ancestral (D614G) strain following primary vaccination,” the company stated.

Both mRNA-1273.351 and mRNA-1273 booster doses were generally well tolerated, the company reported. Safety and tolerability were generally comparable to those reported after the second dose of the original vaccine. Most adverse events were mild to moderate, with injection site pain most common in both groups. Participants also reported fatigue, headache, myalgia, and arthralgia.

The company plans to release data shortly on the booster efficacy at additional time points beyond 2 weeks for mRNA-1273.351, a lower-dose booster with mRNA-1272/351, as well as data on the multivariant mRNA vaccine booster.

In addition to the company’s phase 2 study, the National Institute of Allergy and Infectious Diseases is conducting a separate phase 1 study of mRNA-1273.351.

Both mRNA-1273.351 and mRNA-1273 booster doses were generally well tolerated, the company reported. Safety and tolerability were generally comparable to those reported after the second dose of the original vaccine. Most adverse events were mild to moderate, with injection site pain most common in both groups. Participants also reported fatigue, headache, myalgia, and arthralgia.

The company plans to release data shortly on the booster efficacy at additional time points beyond 2 weeks for mRNA-1273.351, a lower-dose booster with mRNA-1272/351, as well as data on the multivariant mRNA vaccine booster.

In addition to the company’s phase 2 study, the National Institute of Allergy and Infectious Diseases is conducting a separate phase 1 study of mRNA-1273.351.

Use of mRNA COVID-19 vaccines should be considered as the preferable option in the United States rather than Johnson & Johnson’s (J&J) Janssen COVID-19 vaccine in women aged under 50 years, according to one group of experts.

The group made their recommendation in an editorial in JAMA published online April 30, 2021, accompanying a paper describing details of 12 case reports of cerebral venous sinus thrombosis (CVST) with thrombocytopenia following the J&J COVID-19 vaccine, also known as the Ad26.COV2.S vaccine.

The editorialists are Ruth A. Karron, MD, professor of international health at Johns Hopkins University, Baltimore; Nigel S. Key, MD, professor of hematology at the University of North Carolina at Chapel Hill; and Joshua M. Sharfstein, MD, associate dean for public health practice at Johns Hopkins

They noted that, after an initial pause following reports of thrombosis with thrombocytopenia syndrome (TTS) linked to the J&J vaccine, and on the recommendation of the Advisory Committee on Immunization Practices, the United States has permitted the use of the J&J vaccine in all adults with information on the risk of TTS added to educational materials.

The editorialists pointed out that no cases of TTS have been confirmed following administration of more than 180 million doses of the mRNA vaccines in the United States.

They said that, while the J&J vaccine will still be needed for individuals with allergies to components of the mRNA vaccines and for those who live in remote locations where the cold chain for transport and storage of mRNA vaccines cannot be maintained, “U.S. public health agencies and clinicians should consider recommending mRNA vaccines as safer options for those who may be at substantially higher risk for TTS after Ad26.COV2.S vaccination, currently women younger than 50 years.”

In the main JAMA paper, a group led by Isaac See, MD, Centers for Disease Control and Prevention COVID-19 Response Team, reported full details of 12 cases of CVST with thrombocytopenia following the J&J COVID-19 vaccine reported to the U.S. Vaccine Adverse Event Reporting System (VAERS).

The 12 U.S. case reports, 3 of which were fatal, show many similarities to cases described in Europe after the AstraZeneca vaccine.

The authors noted that, by April 12, approximately 7 million doses of the J&J vaccine had been given in the United States. The 12 cases of CVST and thrombocytopenia following receipt of the vaccine were reported to VAERS between March 2 and April 21. All 12 cases were in White women, 11 of whom were aged under 50 years.

As of April 25, a further two cases have been confirmed and reported to VAERS; one in a man younger than 40 years, the other in a woman aged between 40 and 59 years.

In the 12 cases reported in detail, symptoms started between 6 and 15 days post vaccination.

At least one risk factor for CVST was identified in seven patients (obesity in six, hypothyroidism in one, and use of combined oral contraceptives in one). None of the patients was pregnant or within 12 weeks post partum, had prior thrombosis, a personal or family history of thrombophilia, or documented prior exposure to heparin.

In addition to CVST, seven patients had intracerebral hemorrhage and eight had non-CVST thromboses.

One patient reported a history of SARS-CoV-2 infection approximately 4 months prior to vaccination. Of the other 11 patients, 4 had negative serologic tests and 7 were not tested.

All 12 patients were hospitalized and 10 were admitted to an ICU. At the time of the last follow-up, three patients had died (all of whom had intraparenchymal hemorrhage), three remained in the ICU, two were still hospitalized but not in an ICU, and four had been discharged home.

The authors pointed out that the U.S. cases of CVST with thrombocytopenia following the J&J vaccine have many similarities to those reported in Europe after the AstraZeneca vaccine, occurring primarily in women younger than 40 years and in patients without diagnosed thrombophilia. Both European and U.S. patients had a median platelet nadir count of 19 x 103/mcL and several also had non-CVST large-vessel thrombosis.

In the European cases of CVST with thrombocytopenia, 50% of patients died, compared with 25% of U.S. patients.

Like the European cases, the U.S. cases had positive heparin-PF4 HIT antibody enzyme-linked immunosorbent assay tests in the absence of prior exposure to heparin, as would be seen in autoimmune HIT.

However, in the initial European CVST reports, 88% of patients tested with functional platelet HIT antibody tests had positive results, compared with only 11% of the U.S. cases. But the authors noted that lack of standardization in functional platelet HIT antibody assays may lead to differences in results by different laboratories.

“It may be important to notify testing laboratories that postvaccination TTS is being evaluated, so that testing methods can be adjusted if needed,” they said.

They concluded that these case reports suggest that the pathogenesis of TTS may be similar to autoimmune HIT, triggered by the formation of antibodies directed against PF4, a constituent of platelet alpha granules released during platelet activation. In contrast to classic HIT in which exogenous heparin triggers antibody formation, in autoimmune HIT, an endogenous polyanion triggers PF4 antibody formation.

They noted that the precise mechanism of TTS in relation to COVID-19 vaccination has not yet been established. The Global Advisory Committee on Vaccine Safety has stated that a platform-specific mechanism related to adenovirus vector vaccines cannot be excluded. Both the J&J and AstraZeneca vaccines use an adenoviral vector, but they are different; J&J uses a human vector, while AstraZeneca uses a chimpanzee vector.

They also pointed out that CVST and thrombocytopenia following SARS-CoV-2 infection has been reported in at least two cases, but HIT testing was not done in these cases. There have not so far been any reports to VAERS of CVST with thrombocytopenia following mRNA COVID-19 vaccines.

The authors said these findings have important clinical and public health implications, noting that the CDC has updated its interim clinical considerations for use of authorized COVID-19 vaccines to indicate that women aged 18-49 years should be aware of the increased risk of TTS after receipt of the J&J vaccine, and to use a nonheparin anticoagulant in suspected cases.

They noted that a subacute presentation of headache is present in 90% of patients with typical CVST. While headache is a common symptom after the J&J vaccination, most headaches begin and resolve within 2 days. Whereas in the U.S. cases of CVST after vaccination, headache symptoms began at least 6 days after vaccination and persisted for at least a week for most.

“Urgent consultation with a neurologist is prudent when a patient is suspected or confirmed to have CVST. In addition, since the median time from symptom onset to hospitalization was 7 days in the U.S. CVST case series, patient and clinician education might shorten the time to clinical evaluation and therefore treatment,” they stated.

The authors also note that VAERS is a passive surveillance system, so cases of CVST with thrombocytopenia may be underreported.

In their accompanying editorial, Dr. Karron and colleagues pointed out that, in addition to the 12 patients with CVST with thrombocytopenia described in this case series, at least three patients without CVST but meeting diagnostic criteria for TTS have been reported to VAERS (as of April 21), all in women aged 18-59 years (median age, 37 years).

The editorialists reported that the rate of CVST with thrombocytopenia after the J&J vaccine is approximately 5 per million women aged 18-50 years. This is compared with a background rate of approximately 0.05-0.13 per million per month.

They said that the availability of an interim standardized case definition of this adverse effect will facilitate prospective case ascertainment through review of large linked databases and active case finding.

This will also permit greater understanding of whether individuals who are otherwise at increased risk for hypercoagulation in general and for CVST in particular (for example, women taking hormonal contraceptive medications or who are pregnant) are also at increased risk for TTS.

Obtaining this information will support dynamic country-specific assessments of the risks of each vaccine, compared with the risk of COVID-19 disease for their populations and subpopulations, they added.

New cases of COVID-19 in children are trending downward again after dropping for a second consecutive week, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

Despite that drop, however, children made up a larger share (22.4%) of all cases reported during the week of April 23-29, compared with the previous week, when the proportion reached what was then a pandemic high of 20.8%, based on data in the weekly AAP/CHA report.

New cases totaled 71,649 for the week of April 23-29, down by 10.3% from the week before and by 19.0% over this most recent 2-week decline, but still a ways to go before reaching the low point of the year (52,695) recorded during the second week of March, the report shows.

Since the beginning of the pandemic, just over 3.78 million children have been infected by SARS-CoV-2, which is 13.8% of all cases reported in 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

The overall rate of COVID-19 has reached 5,026 cases per 100,000 children, or 5% of the total pediatric population, although there is considerable variation among the states regarding age ranges used to define child cases. Most states use a range of 0-17 or 0-19 years, but Florida and Utah use a range of 0-14 years and South Carolina and Tennessee go with 0-20, the AAP and CHA noted.

There is also much variation between the states when it comes to cumulative child COVID-19 rates, with the lowest rate reported in Hawaii (1,264 per 100,000) and the highest in North Dakota (9,416 per 100,000). The lowest proportion of child cases to all cases is found in Florida (8.7%) and the highest in Vermont (22.2%), the AAP and CHA said.

The number of COVID-19–related deaths was 303 as of April 29, up by 7 from the previous week in the 43 states, along with New York City, Puerto Rico, and Guam, that are reporting mortality data by age. The proportion of child deaths to child cases remains at 0.01%, and children represent just 0.06% of all COVID-19 deaths, according to the AAP/CHA report.

Asthma care coordination for children can be improved through a school-based asthma program involving the child’s school, their family, and clinicians, according to a recent presentation at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.

“Partnerships among schools, families, and clinicians can be powerful agents to improve the recognition of childhood asthma symptoms, asthma diagnosis and in particular management,” Sujani Kakumanu, MD, clinical associate professor of allergy and immunology at the University of Wisconsin–Madison, said in her presentation. “Emergency treatment plans and asthma action plans, as well as comprehensive education for all school personnel and school environmental mitigation plans, are crucial to controlling asthma symptoms in schools.”

The school is a unique location where families and clinicians can affect asthma outcomes because of the consistent amount of time a student spends there each day, Dr. Kakumanu explained, but everyone involved in allergy care for a child should be aware of and attempt to reduce environmental exposures and triggers found in schools that can worsen asthma, such as irritants, cleaning solutions, dust mites, pests, air pollution, and indoor air quality.
 

SAMPRO expansion

In 2016, the AAAAI and National Association of School Nurses provided financial support for the School-based Asthma Management Program (SAMPRO). “The impetus behind this initiative was a recognition that coordination with schools was essential to controlling pediatric asthma care,” Dr. Kakumanu said. Initially focusing on asthma alone, SAMPRO has since expanded to include resources for allergy and anaphylaxis and is known as the School-based Asthma, Allergy & Anaphylaxis Management Program (SA3MPRO).

SA3MPRO’s first tenet is the need for an engaged circle of support that includes families, schools, and clinicians of children with asthma. “Establishing and maintaining a healthy circle of support is a critical component to a school-based asthma partnership. It requires an understanding of how care is delivered in clinics as well as in hospitals and at schools,” Dr. Kakumanu said.

School nurses are uniquely positioned to help address gaps in care for children with asthma during the school day by administering medications and limiting the number of student absences caused by asthma. “In addition, school nurses and school personnel often provide key information to the health system about a student’s health status that can impact their prescriptions and their medical care,” she noted.
 

Setting an action plan

The second SA3MPRO tenet is the development of an asthma action plan by schools for situations when a child presents with urgent asthma symptoms that require quick action. SA3MPRO’s asthma action plan describes a child’s severity of asthma, known asthma triggers and what medications can be delivered at school, and how clinicians and schools can share HIPAA and FERPA-protected information.

Some programs are allowing school nurses to access electronic medical records to share information, Dr. Kakumanu said. UW Health at the University of Wisconsin developed the project, led by Dr. Kakumanu and Robert F. Lemanske Jr., MD, in 2017 that gave school nurses in the Madison Metropolitan School District access to the EMR. Prior to the COVID-19 pandemic, the program was linked to decreased prescriptions of steroids among pediatric clinicians, she said.

“This program allowed the quick and efficient delivery of asthma action plans to schools along with necessary authorizations, prescriptions and a consent to share information electronically. With this information and subsequent authorizations, the school nurses were able to update the school health record, manage symptoms at school as directed by the individualized asthma action plan, and coordinate school resources needed to care for the child asthma symptoms during the school day,” Dr. Kakumanu said.

“This program also addressed a common barrier with school-based partnerships, which was the lack of efficient asynchronous communication, and it did this by including the ability of school nurses and clinicians to direct message each other within a protected EMR,” she added. “In order to continue our support for families, there were also measures to include families with corresponding [EMR] messaging and with communication by phone.”

Barriers in the program at UW Health included needing annual training, sustaining momentum for organizational support and interest, monitoring infrastructure, and maintaining documents. Other challenges were in the management of systems that facilitated messaging and the need to obtain additional electronic consents separately from written consents.
 

Training vital

The third tenet in SA3MPRO is training, which should incorporate a recognition and treatment of asthma symptoms among school staff, students, and families; proper inhaler technique; how medical care will be delivered at the school and by whom; what emergency asthma symptoms look like; and a plan for getting the child to an emergency medical facility. “Regardless of the program that is chosen, asthma education should address health literacy and multiple multicultural beliefs and be delivered in the language that is appropriate for that school and that student body,” Dr. Kakumanu said. “Teachers, janitors, school administrators, and all levels of school personnel should be educated on how to recognize and treat asthma symptoms, especially if a school nurse is not always available on site.”

Marathon not a sprint

The last tenet in SA3MPRO is improving air quality and decreasing environmental exposure to triggers, which involves “the use of environmental recognition and mitigation plans to minimize the effect of allergens, irritants, and air pollutants within the outside and indoor environment that may affect a child with asthma during the school day.”

While these measures may seem daunting, Dr. Kakumanu said the communities that have successfully implemented a SA3MPRO plan are ones that prioritized updated and accurate data, developed a team-based approach, and secured long-term funding for the program. “Important lessons for all of us in this work is remembering that it’s a marathon and not a sprint, and that effective care coordination requires continual and consistent resources,” she said.

Dr. Kakumanu reported no relevant conflicts of interest.

Asthma care coordination for children can be improved through a school-based asthma program involving the child’s school, their family, and clinicians, according to a recent presentation at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.

“Partnerships among schools, families, and clinicians can be powerful agents to improve the recognition of childhood asthma symptoms, asthma diagnosis and in particular management,” Sujani Kakumanu, MD, clinical associate professor of allergy and immunology at the University of Wisconsin–Madison, said in her presentation. “Emergency treatment plans and asthma action plans, as well as comprehensive education for all school personnel and school environmental mitigation plans, are crucial to controlling asthma symptoms in schools.”

The school is a unique location where families and clinicians can affect asthma outcomes because of the consistent amount of time a student spends there each day, Dr. Kakumanu explained, but everyone involved in allergy care for a child should be aware of and attempt to reduce environmental exposures and triggers found in schools that can worsen asthma, such as irritants, cleaning solutions, dust mites, pests, air pollution, and indoor air quality.

The Food and Drug Administration could expand the use of the Pfizer COVID-19 vaccine to teens early next week, The New York Times and CNN reported, both citing unnamed officials familiar with the agency’s plans.

In late March, Pfizer submitted data to the FDA showing its mRNA vaccine was 100% effective at preventing COVID-19 infection in children ages 12 to 15. Their vaccine  is already authorized for use teens and adults ages 16 and older.

The move would make about 17 million more Americans eligible for vaccination and would be a major step toward getting both adolescents and teens back into classrooms full time by next fall.

“Across the globe, we are longing for a normal life. This is especially true for our children. The initial results we have seen in the adolescent studies suggest that children are particularly well protected by vaccination, which is very encouraging given the trends we have seen in recent weeks regarding the spread of the B.1.1.7 U.K. variant,” Ugur Sahin, CEO and co-founder of Pfizer partner BioNTech, said in a March 31 press release.

Getting schools fully reopened for in-person learning has been a goal of both the Trump and Biden administrations, but it has been tricky to pull off, as some parents and teachers have been reluctant to return to classrooms with so much uncertainty about the risk and the role of children in spreading the virus.

A recent study of roughly 150,000 school-aged children in Israel found that while kids under age 10 were unlikely to catch or spread the virus as they reentered classrooms. Older children, though, were a different story. The study found that children ages 10-19 had risks of catching the virus that were as high as adults ages 20-60.

The risk for severe illness and death from COVID-19 rises with age.

Children and teens are at relatively low risk from severe outcomes after a COVID-19 infection compared to adults, but they can catch it and some will get really sick with it, especially if they have an underlying health condition, like obesity or asthma that makes them more vulnerable.

Beyond the initial infection, children can get a rare late complication called MIS-C, that while treatable, can be severe and requires hospitalization. Emerging reports also suggest there are some kids that become long haulers in much the same way adults do, dealing with lingering problems for months after they first get sick.

As new variants of the coronavirus circulate in the United States, some states have seen big increases in the number of children and teens with COVID. In Michigan, for example, which recently dealt with a spring surge of cases dominated by the B.1.1.7 variant, cases in children and teens quadrupled in April compared to February.

Beyond individual protection, vaccinating children and teens has been seen as important to achieving strong community protection, or herd immunity, against the new coronavirus.

If the FDA expands the authorization for the Pfizer vaccine, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will likely meet to review data on the safety and efficacy of the vaccine. The committee may then vote on new recommendations for use of the vaccine in the United States.

Not everyone agrees with the idea that American adolescents, who are at relatively low risk of bad outcomes, could get access to COVID vaccines ahead of vulnerable essential workers and seniors in other parts of the world that are still fighting the pandemic with little access to vaccines.

Teens with persistent nocturnal asthma symptoms were significantly more likely than were those without nighttime asthma to report poor functional health independent of daytime asthma, based on data from 430 adolescents aged 12-16 years.

Approximately half of children with severe asthma experience at least one night of inadequate sleep per week, and lost sleep among young children with asthma has been associated with impaired physical function, school absence, and worsened mood. However, the effect of asthma-related sleep disruption on daily function in teenagers in particular has not been well studied, according to Anne Zhang of the University of Rochester (N.Y.) and colleagues.

In a poster presented at the virtual meeting of the Pediatric Academic Societies (#542), the researchers reviewed baseline survey data from the School-Based Asthma Care for Teens (SB-ACT) study, a randomized, controlled trial conducted from 2014 to 2018 in Rochester, N.Y.

The average age of the respondents was 13.4 years, 56% were male, 56% were African American, 32% were Hispanic, and 84% had Medicaid insurance.

Persistent nocturnal asthma was defined as 2 or more nights of nighttime awakening in the past 14 days, and intermittent nocturnal asthma was defined as less than 2 nights of nighttime awakening in the past 14 days.

Overall, teens with persistent nocturnal asthma were significantly more likely than were those with intermittent nocturnal asthma to report physical limitations during strenuous activity (58% vs. 41%), moderate activity (32% vs. 19%), and school gym classes (36% vs. 19%; P <.01 for all).

In addition to physical impact, teens with persistent nocturnal asthma were more likely than were those with intermittent nocturnal asthma to report depressive symptoms (41% vs. 23%), asthma-related school absences in the past 14 days (0.81 vs. 0.12), and poorer quality of life (4.6 vs. 5.9, P <.01 for all).

The results remained significant in a multivariate analysis that controlled for daytime asthma symptoms, weight status, race, ethnicity, gender, age, and smoke exposure, the researchers said.

The study findings were limited by several factors including the cross-sectional design, potential of recall bias in survey responses, and lack of data on sleep duration and quality, the researchers noted.

However, the results suggest that improving nighttime asthma control for teens may improve daily function, and providers should ask teens with asthma about the possible effect and burden of nighttime symptoms, they said. Potential strategies to improve persistent nocturnal asthma symptoms include adjusting the timing of medications or physical activity, they added.

“We know that getting adequate, high-quality sleep is important for health - especially for adolescents,” said Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, in an interview. “Just like adults, tired teens are not able to function at their best and are at higher risk of developing mood problems,” she said.

However, “There are already so many barriers for teens getting good sleep, such as screen time/social media, homework, busy social calendars, caffeine use, and early morning school start times,” she said. Underlying medical conditions such as depression, anxiety, and obstructive sleep apnea also can contribute to poor sleep for teens, she added.

“In my practice, I frequently counsel about sleep hygiene because it is so essential and not commonly followed,” said Dr. Curran. “Nocturnal asthma is another contributor to poor sleep - not one that I have been regularly screening for - and something we can potentially intervene in to help improve health and quality of life,” she emphasized.

Dr. Curran said that she was not surprised by the study findings, given what is known about the importance of sleep. In clinical practice, “Teens who have asthma should be screened for nocturnal symptoms as these are linked to worsened quality of life, including limitations in activities, depressive symptoms, and asthma-related school absence,” she said.

However, additional research is needed to better understand whether improving nocturnal asthma symptoms can help improve quality of life and daily functioning in adolescents, she noted.

The SB-ACT was supported by the National Institutes of Health. Ms. Zhang was supported in part by the OME-CACHED for medical student research and an NIH grant. The researchers had no financial conflicts to disclose. Dr. Curran had no financial conflicts to disclose.

In addition to physical impact, teens with persistent nocturnal asthma were more likely than were those with intermittent nocturnal asthma to report depressive symptoms (41% vs. 23%), asthma-related school absences in the past 14 days (0.81 vs. 0.12), and poorer quality of life (4.6 vs. 5.9, P <.01 for all).

The results remained significant in a multivariate analysis that controlled for daytime asthma symptoms, weight status, race, ethnicity, gender, age, and smoke exposure, the researchers said.

The study findings were limited by several factors including the cross-sectional design, potential of recall bias in survey responses, and lack of data on sleep duration and quality, the researchers noted.

However, the results suggest that improving nighttime asthma control for teens may improve daily function, and providers should ask teens with asthma about the possible effect and burden of nighttime symptoms, they said. Potential strategies to improve persistent nocturnal asthma symptoms include adjusting the timing of medications or physical activity, they added.

“We know that getting adequate, high-quality sleep is important for health - especially for adolescents,” said Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, in an interview. “Just like adults, tired teens are not able to function at their best and are at higher risk of developing mood problems,” she said.

However, “There are already so many barriers for teens getting good sleep, such as screen time/social media, homework, busy social calendars, caffeine use, and early morning school start times,” she said. Underlying medical conditions such as depression, anxiety, and obstructive sleep apnea also can contribute to poor sleep for teens, she added.

“In my practice, I frequently counsel about sleep hygiene because it is so essential and not commonly followed,” said Dr. Curran. “Nocturnal asthma is another contributor to poor sleep - not one that I have been regularly screening for - and something we can potentially intervene in to help improve health and quality of life,” she emphasized.

Dr. Curran said that she was not surprised by the study findings, given what is known about the importance of sleep. In clinical practice, “Teens who have asthma should be screened for nocturnal symptoms as these are linked to worsened quality of life, including limitations in activities, depressive symptoms, and asthma-related school absence,” she said.

However, additional research is needed to better understand whether improving nocturnal asthma symptoms can help improve quality of life and daily functioning in adolescents, she noted.

A newly released report is offering guidance concerning rare conditions associated with COVID-19 as well as vaccines against the virus.

The report was released April 29, 2021, by the American Heart Association/American Stroke Association Stroke Council Leadership in answer to the decision April 23 by the Centers for Disease Control and Prevention and the Food and Drug Administration to lift an earlier “pause” in administration of the Johnson & Johnson (Janssen) vaccine.

That pause had been put in place after reports were received of a possible association between the J&J vaccine and cerebral venous sinus thrombosis (CVST) and thrombosis-thrombocytopenia syndrome (TTS, blood clots plus low blood platelets). CVST and TTS were also linked to patients in Europe and Canada who received the AstraZeneca COVID-19 vaccine.

However, the new report noted that these conditions are very rare.

“The risk of CVST due to infection with COVID-19 is 8-10 times higher than the risk of CVST after receiving a COVID-19 vaccine,” lead author Karen L. Furie, MD, chair of the department of neurology at Brown University, Providence, R.I., said in a press release.

“The public can be reassured by the CDC’s and FDA’s investigation and these statistics – the likelihood of developing CVST after a COVID-19 vaccine is extremely low,” said Dr. Furie, adding that the authors “urge all adults to receive any of the approved COVID-19 vaccines.”

The new guidance, which was published online April 29, 2021, in Stroke, discusses signs and symptoms of CVST and TTS, as well as vaccine-induced immune thrombotic thrombocytopenia (VITT). It also recommends best options for treating these conditions.
 

Assessing 81 million patients

In their analysis, the investigators assessed a database of 59 health care organizations and 81 million patients, 98% of whom were in the United States.

Of almost 514,000 patients diagnosed with COVID-19 between January 2020 and March 2021, 20 also received a diagnosis of CVST.

Among about 490,000 adults who received either the Pfizer or Moderna vaccines, there were no diagnosed cases of thrombocytopenia.

Dr. Furie reiterated that CVST blood clots “are very rare adverse events,” but recommended that any patient in the ED with a suspected clot should be screened immediately to determine if they received a COVID vaccine during the previous few weeks.

For those who have recently received the COVID-19 vaccine, a suspected clot should be treated with nonheparin anticoagulants, Dr. Furie said.

“No heparin products in any dose should be given for suspected CVST, TTS, or VITT. With the right treatment, most patients can have a full recovery,” she added. The report includes additional, detailed treatment recommendations if one of these conditions are suspected. 
 

Rare events

The authors noted that cases of TTS/VITT occurred up to 2.5 weeks after receiving the J&J vaccine in the United States and up to 3.5 weeks after receiving the AstraZeneca vaccine in Europe.

An April 23 report from the CDC and FDA noted that, out of almost 7 million adults who received the J&J vaccine, the agencies investigated only 15 reported cases of TTS.

An April 7 report from the European Medicines Agency noted that, out of more than 25 million people who received the AstraZeneca vaccine in the European Union, it found 62 cases of CVST.

A statement put out by the American Heart Association/American Stroke Association urges “everyone to receive a COVID-19 vaccine” as soon as possible.

“We are confident the benefits of vaccination far exceed the very small, rare risks,” the organizations said. “The risks of vaccination are also far smaller than the risk of COVID-19 and its potentially fatal consequences.”
