One year follow up for case series of myocarditis following mRNA vaccination against SARS-CoV-2

Abstract

In 2021, the first rounds of modified mRNA vaccines against SARS-CoV-2 were tested and deployed. The vaccines themselves had great efficacy against severe infection, with rare and minimal side effects. One adverse effect that was reported, however, was incidence of myocarditis seen amongst mostly young males after their second vaccination dose. The disease course was self-limited. This study group published a case series in August of 2021 of four cases of this phenomenon. This paper is a followup to the original case series, providing an updated literature review and expert recommendations concerning the safety and benefits of the vaccines.
