Youth in Ontario Experience Myocarditis or Pericarditis after BNT162b2 Vaccination

JAMA Network

About The Study: The results of this study of 1.65 million doses of BNT162b2 (Comirnaty [Pfizer-BioNTech]) vaccinations among adolescents in Ontario, Canada, suggest that there was variation in the reported incidence of myocarditis or pericarditis. However, the risk of these events after vaccination remains very rare and should be considered in relation to the benefits of COVID-19 vaccination.
