Study examined myocarditis risks linked to COVID-19 mRNA vaccination, COVID-19 infection, and other causes. It found increased myocarditis incidence after vaccination but significantly lower mortality and hospitalization rates compared to myocarditis from other causes.

Although myocarditis often self-corrects, severe cases may require months or even years of medical intervention to resolve, thereby resulting in significant debilitation and economic burden to affected patients and their families. Since COVID-19 is associated with an increased myocarditis risk, and vaccines have been proven to significantly reduce the risk of COVID-19 and improve post-COVID outcomes, understanding the impacts of COVID-19 vaccination would allow clinicians and policymakers to clarify the benefits and possible risks associated with vaccinations across relevant demographics.

For the analysis, study participants were classified as postvaccine myocarditis if they were hospitalized within seven days following COVID-19 mRNA vaccination or post-COVID-19 myocarditis if they were hospitalized within 30 days of COVID-19 diagnosis without prior immunization.
