CDC Investigates Reports of Heart Inflammation After COVID Inoculations

The U.S. Centers for Disease Control and Prevention says it is investigating reports  that young people have developed myocarditis, or heart inflammation, after being inoculated with a COVID-19 vaccine.

The agency’s vaccine safety group said in a recent report that there have been “relatively few reports“ of the heart inflammation, but most tended to occur in male teenagers and young adults, usually after a second vaccine dose. “Most cases appear to be mild, and follow-up of cases is ongoing,” the safety group said. In another development, two doses of the COVID-19 vaccines made by Pfizer-BioNTech or AstraZeneca are about as effective against the coronavirus variant first found in India as they are against the variant first found in England, according to a study by Public Health England announced Saturday.
