Myocarditis is inflammation of the heart muscle.
Pericarditis is inflammation of the pericardium (the thin, sac-like tissue surrounding the heart muscle).
Myocarditis and pericarditis can occur together or separately.
The risk of myocarditis is higher (although still rare) after vaccination with Moderna original formulation compared with Pfizer original formulation. It is estimated there are around 2 more cases per 100,000 second vaccine doses in people under 40 who received Moderna original formulation than Pfizer original formulation.
Evidence suggests that AstraZeneca and Novavax are probably associated with a small increased risk of myocarditis and pericarditis.
This risk after AstraZeneca looked lower than the risk after Moderna original formulation or Pfizer original formulation.
A longer interval between doses of the primary course may reduce the likelihood of myocarditis and pericarditis by a small amount.
