Detailed Description

This is an observational cohort study that combines data collected directly from healthcare providers (HCP) with existing retrospective real-world data as captured in clinical electronic health record (EHR) and administrative claims data. Vaccine exposure and case identification information will be obtained retrospectively from existing real-world data to identify cases of post-vaccine myocarditis (PVM) and ultimately vaccine-associated myocarditis (VAM) for potential study inclusion. Eligible participants will be identified and followed for up to 5 years until the end of the study period or loss to follow-up or death.
