In this paper they report the MRI findings of myocarditis in five patients who recently received the COVID-19 mRNA vaccine. Patients 1–3 received their second dose of BNT162b2 vaccine 2 days, 3 days, and 2 days, respectively, before the onset of chest pain. Patients 4 and 5 received their second dose of mRNA-1273 3 days before the onset of chest pain. The clinical presentation, temporal relationship, lymphadenopathy, and negative history of COVID-19 raise concern for vaccine-associated myocarditis.
