FDA adds a warning to Covid-19 vaccines about risk of heart inflammation
CNN
The FDA added a warning about the risk of myocarditis and pericarditis to fact sheets for Moderna and Pfizer-BioNTech Covid-19 vaccines Friday.
The warning notes that reports of adverse events following vaccination -- particularly after the second dose -- suggest increased risks of both types of heart inflammation. Earlier this week, vaccine advisers to the US Centers for Disease Control and Prevention heard that the agency had received about 1,200 reports of such heart inflammation after 300 million doses of the two vaccines had been given. CDC has confirmed about 300 of those cases, many of them among young men and adolescents.More Related News
