Heart Complication (Myocarditis) Rare After COVID-19 Vaccination

Cases of myocarditis after COVID-19 vaccination are rare.

Did you know?

Rare instances of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the outer lining of the heart) have been reported in children age 12-17 (mostly male) after vaccination. This is not a common side effect. In fact, according to the Centers for Disease Control and Prevention, one study found that the risk of myocarditis after the second dose of the Pfizer-BioNTech vaccine one week following vaccination was around 54 cases per million (in males age 12–17). Most individuals who experience these side effects and receive care respond well to medical treatment and quickly feel better.
