The European Medicines Agency decided on July 19, 2021 that myocarditis and pericarditis be added to the list of adverse effects of both messenger RNA (mRNA) based vaccines (BNT162b2 [Pfizer-BioNTech] and mrna-1273 [Moderna]) against COVID-19. This advice was based on numerous reports of myocarditis that followed a clinical pattern that strongly suggested a causal link between these particular vaccines and myocarditis/pericarditis. The adverse events that appeared to be predominantly in young men typically occurred within a week after injection, and were clustered after the second dose of the vaccine series. A recent national database from France sheds some light on the approximate rates of mrna vaccine related myocarditis.
