Myocarditis in children after COVID‑19 vaccine

Abstract

Three healthy adolescents presented with myocarditis confirmed on cardiac magnetic resonance imaging after receiving Pfizer‑BioNTech COVID‑19 vaccine. All patients were hemodynamically stable and had good short‑term outcomes. Long‑term outcomes are yet to be determined. Larger studies are needed to determine whether an association between Pfizer‑BioNTech COVID‑19 vaccine and myocarditis exists.
