Study: Immune cells—not antibodies—cause COVID vaccine-linked myocarditis

---

The rare cases of myocarditis among recipients of mRNA vaccines are caused by a generalized immune-cell and inflammatory response, researchers say.

The rare cases of myocarditis among recipients of mRNA COVID-19 vaccine—mostly in young men—are caused by a generalized immune-cell and inflammatory response rather than vaccine-triggered antibodies, suggests a small study published late last week in Science Immunology.

…

The risk of COVID-19 vaccine–associated myocarditis is very rare, affecting about 22 to 36 in 100,000 12- to 17-year-old boys who received their second dose no more than 21 days earlier, according to the Centers for Disease Control and Prevention. In fact, myocarditis is more common after COVID-19 infection among unvaccinated boys, at 50 to 65 cases per 100,000.
