France is investigating five cases of myocarditis – inflammation of the heart muscle – which were detected in people who had received Pfizer/BioNTech’s coronavirus vaccine. Several cases of myocarditis were detected in Israel after a second dose of the vaccine, which led ANSM Monitoring Committee “to re-examine the data on inflammation of both the heart muscle and the pericardium collected by the regional pharmacovigilance centres (CRPV) in France since the start of the vaccination campaign.”
