Myocarditis is inflammation of the heart muscle. This can happen after viral infections like COVID-19 and, very rarely, after receiving mRNA COVID-19 vaccines.
Most people with myocarditis following vaccination recover completely with rest
and simple treatment. However, myocarditis from COVID-19 can be very severe.
