The Centers for Disease Control and Prevention took a highly cautious approach to the coronavirus vaccines when it temporarily paused the Johnson & Johnson shots earlier this year. But now, as the agency considers hundreds of reports of heart inflammation among young adults, there's more will to push forward without modifying the official vaccine recommendations. There's a "likely association" between the heart condition and shots of the mRNA vaccines.That was the conclusion reached by members of a CDC advisory panel, who spent part of yesterday reviewing reports of rare cases of myocarditis — inflammation of the heart muscle — predominantly in males ages 12 to 39. The cases chiefly occurred within five days of receiving a shot of the Pfizer or Moderna vaccine. "Most cases have been mild and have taken place several days to a week after the second shot," The Post's Lena H. Sun reports. "Chest pain is the most common symptom. Patients generally recover from symptoms and do well." The cases of myocarditis are extremely rare: There were 1,226 reports of the condition out of about 300 million mRNA doses administered in the United States as of June 11. Of those, 267 were reported after the first dose and 827 after the second; 132 reports didn't indicate which dose. - In males 12 to 39, the risk of myocarditis after the second dose of any mRNA vaccine was 32 cases per million, or about 1 in 31,000, according to a CDC analysis of data from one of several vaccine safety monitoring systems.
- For females in that age group, there were 4.7 cases per million, or about 1 in 212,000.
- By comparison, the estimated incidence of the rare inflammatory syndrome in children is about 1 in every 3,200 covid-19 infections — with 36 percent of cases reported in those ages 12 to 20.

"Especially with the troubling Delta variant increasingly circulating, and more readily impacting younger people, the risks of being unvaccinated are far greater than any rare side effects from the vaccines," the statement said. "The CDC and the Food and Drug Administration plan to do a three-month follow-up of these cases," Lena writes. "Both agencies are also updating their fact sheets for providers and patients to reflect the additional data about the condition." "The choice to avoid an mRNA vaccine in order to avoid myocarditis ignores the fact that both covid and MIS-C [a rare inflammatory condition diagnosed in some children after covid infections] cause myocarditis, and far more commonly," said Paul A. Offit, a vaccine expert at Children's Hospital of Philadelphia. "There are no risk-free choices." Baylor University professor Peter Hotez made the same point: | | | But some experts questioned whether administering a second dose is necessary or wise.Most of the myocarditis events occurred after receiving a second shot, they noted. A new study from Israeli researchers suggests the Pfizer vaccine provides full protection to kids between 12 and 15 after a single dose. Ben-Gurion University's Nadav Davidovitch, who led the research, told The Jerusalem Post that a single dose could be considered for young teengers "both because the second dose adds relatively little, if any, immunogenicity and we know that for some young people there can be complications like myocarditis." While Israel has been vaccinating teenagers for weeks, several other developed countries are holding back. Germany is offering just one vaccine dose to young people. In the U.K., vaccine experts aren't likely to recommend anytime soon that those ages 12-15 get the shots. Johns Hopkins professor Marty Makary: | | | Venkatesh Murthy, a cardiologist at University of Michigan: | | | Monica Gandhi, an infectious disease doctor at University of California: | | | The World Health Organization isn't recommending that those under age 18 get the shots. In new guidance issued this week, WHO wrote that "more evidence is needed on the use of the different COVID-19 vaccines in children to be able to make general recommendations on vaccinating children against COVID-19." WHO's Strategic Advisory Group of Experts did conclude the Pfizer vaccine is suitable for use by people aged 12 years and above, but the agency is still recommending it only for those in high-risk categories. "Children aged between 12 and 15 who are at high risk may be offered this vaccine alongside other priority groups for vaccination," says guidance on the agency's website. "Vaccine trials for children are ongoing and WHO will update its recommendations when the evidence or epidemiological situation warrants a change in policy." The evolving data make it harder for experts to answer questions from anxious parents."We worry a little bit about, are we going to make the community nervous, or have them be more hesitant to vaccinate?" Patricia Stinchfield, director of infectious-disease control at Children's Minnesota, a liaison from the National Association of Pediatric Nurse Practitioners, told Lena. But, she added, the discussion "allows us to have conversations. … And the parents that I have talked to, which are numerous about this, are very appreciative of that. And [they] do go ahead and vaccinate and are very, very happy that we're doing this kind of deep analysis, even on rare events." |
