What The Study Did: In this population-based study of almost 2.4 million people who received at least one dose of COVID-19 mRNA vaccines, acute myocarditis was rare, at an incidence of 5.8 cases per 1 million individuals after the second dose (1 case per 172,414 fully vaccinated individuals). The signal of increased myocarditis in young men warrants further investigation.
