Acute myocarditis is a rare complication of the widely used mRNA-based vaccines. Case Presentation: 20-year old male with no preexisting disease or cardiovascular risk factor presented in October 2021 with chest pain after receiving the second dose of the Moderna COVID-19 vaccine 2 days previously. He discharged from ward care only a few days after his initial presentation. Conclusion: Despite the meta-analysis results suggesting a higher risk of myocarditis with COVID-19 vaccination, vaccination should still be recommended because benefits of the vaccine likely outweigh its harms. %K COVID-19 %K mRNA-Based Vaccine %K Myocarditis %K Spike Protein %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=124014
