How often do COVID vaccines cause heart problems in kids?
November 3, 2021
While the COVID-19 vaccines made by Pfizer-BioNTech and Moderna do seem to be associated with an increased risk of myocarditis, the latest data indicate that the absolute risk remains very small and that most cases are mild and resolve quickly.
Federal regulators are reviewing data on the link between Moderna's coronavirus vaccine and a rare heart problem in adolescents, the company announced Sunday. That side effect - myocarditis, an inflammation of the heart muscle - has also worried advisers to federal agencies in deliberations regarding use of the Pfizer-BioNTech vaccine in younger children and teenagers.
Scientists advising the Centers for Disease Control and Prevention will review the latest data on the condition at a meeting Tuesday before deciding whether to recommend the Pfizer-BioNTech vaccine for younger children.
So how common is myocarditis, really? And should parents be concerned about vaccinating their children?
