The U.S. Food and Drug Administration (FDA) has added a warning about the risk of heart inflammation to the fact sheets for the Modern and Pfizer-BioNTech COVID-19 vaccines.

By the end of the second week of June, more than 1,200 cases of myocarditis or pericarditis had been reported to the U.S. vaccine adverse event reporting system.

Cases appear to be markedly higher in men and in the week following the second dose of vaccine.

There have been no comments for Pfizer and Moderna yet.
