Key information

About this study

Population-based retrospective studies suggest an association between BNT162b2 (Pfizer-BioNTech) vaccination against coronavirus disease 2019 (COVID-19) and myocarditis. While the overall incidence of myocarditis is estimated to be 2.13 per 100,000 persons, the incidence of myocardial injury and subclinical myocarditis may be higher. Adult health care workers who received the BNT162b2 vaccine in two Israeli hospitals (SZMC and Shamir) during the fourth dose campaign had blood samples taken for high-sensitivity cardiac troponin (hs-cTn) measurement at the time of vaccine administration and after 2-4 days. Post-vaccine myocardial injury was defined as hs-cTn elevation above the 99th percentile upper reference limit and >50% increase from the first measurement. Participants with evidence of myocardial injury underwent assessment for possible myocarditis including electrocardiogram and echocardiography.
