COVID-19 vaccines are associated with rare cardiac adverse events, primarily mild myocarditis and pericarditis in young males, but the overall benefits of vaccination outweigh the risks.
In Singapore, 9.03 million doses of the mRNA COVID-19 vaccines by Pfizer-BioNTech and Moderna have been administered, and 4.46 million people are fully vaccinated. An additional 87,000 people have been vaccinated with vaccines in World Health Organization's Emergency Use Listing. The aim of this review is to explore the reported cardiac adverse events associated with different types of COVID-19 vaccines. A total of 42 studies that reported cardiac side effects after COVID-19 vaccination were included in this study. Reported COVID-19 vaccine-associated cardiac adverse events were mainly myocarditis and pericarditis, most commonly seen in adolescent and young adult male individuals after mRNA vaccination. Reports of other events such as acute myocardial infarction, arrhythmia and stress cardiomyopathy were rare. Outcomes of post-vaccine myocarditis and pericarditis were good. Given the good vaccine efficacy and the high number of cases of infection, hospitalisation and death that could potentially be prevented, COVID-19 vaccine remains of overall benefit, based on the current available data.

Ho et al. (2021) conducted a review in Cardiac adverse events post-COVID-19 vaccination. COVID-19 vaccination was evaluated on Cardiac adverse events. COVID-19 vaccination is associated with rare cardiac adverse events, primarily myocarditis and pericarditis in young males after mRNA vaccines, which generally have good clinical outcomes.
