• Abstract: ABSTRACT Objective: Examine the relationship of myocarditis after COVID-19 vaccination in adults, with conclusion the frequency, severity and management of the condition associated with mRNA vaccines. Methods: A literature review was conducted using PubMed and the Regional Portal of the Virtual Health Library of the Ministry of Health, employing descriptors such as “Risk,” “Myocarditis,” “Vaccines,” and “COVID-19.” Thirty relevant articles were selected that investigated the relationship between COVID-19 vaccination and myocarditis. Results: The review revealed that post-vaccination myocarditis is rare and generally mild, with a higher incidence observed in young men after the second dose of mRNA vaccines. Most cases are treatable and recovery is rapid. Compared to the risk of myocarditis associated with COVID-19 infection, which is more severe and has worse outcomes, the post-vaccination risk is significantly lower. Final Considerations: The findings highlight that, despite the small risk of myocarditis associated with mRNA vaccines, the benefits of vaccination outweigh the risks, particularly in preventing severe COVID-19 complications. The analysis reinforces the importance of vaccination as an effective public health strategy and suggests the need for continuous monitoring and possible adjustments to vaccination recommendations to ensure maximum safety.
