| Cases of myopericarditis after receiving coronavirus disease 2019 (COVID-19) vaccines have been reported, although most cases have been mild. |
| Similar to myocardial and pericardial involvement in the setting of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, COVID-19 vaccine-related myopericarditis can be associated with inappropriate inflammatory response, and anti-inflammatory drugs are noted as useful for treatment. |
| Prospective studies are necessary to determine whether the vaccine-related myopericarditis is casual or causal. |
