Sponsor's own description

The coronavirus disease 2019 (COVID-19) is an ongoing pandemic which has infected more than 160 million people and caused 3.4 million deaths worldwide till May 2021. With the recent rollout of COVID-19 vaccines globally and in Singapore, reports of rare but serious cardiovascular-related side effects started to appear. Although a link between adenovirus-based vaccines (AstraZeneca ChAdOx1 and J\&J Ad26.COV2.S) and cerebral venous sinus thrombosis (CVST) and immune thrombocytopenia has been widely reported, these vaccines are current not in use in Singapore. Yet, acute myocarditis and other cardiovascular symptoms has also been observed to be associated with the two mRNA-based vaccines (Pfizer-BioNTech BNT162b2 and Moderna mRNA-1273) in-use in Singapore. In Singapore acute myocarditis is of particular concern with at least 12 cases reported by the Health Services Authority (HSA). The US FDA and EU authorities have confirmed there to be an association between the mRNA vaccines and myocarditis.The study aims to (1) To study possible mechanisms of COVID-19 vaccines in causing myocarditis in patients with confirmed vaccine-associated myocarditis (2) To risk stratify for vaccine-associated myocarditis in the at-risk population of young men (3) To identify potential preventative strategies to mitigate vaccine-associated myocarditis in high-risk individuals
