Advisers to the Centers for Disease Control and Prevention are scheduled to meet on Wednesday to address reports of rare heart problems in young people immunized with the coronavirus vaccines made by Pfizer-BioNTech and Moderna.
The reports involve conditions called myocarditis, inflammation of the heart muscle; and pericarditis, inflammation of the membrane surrounding the heart. Most cases have been mild, with symptoms like fatigue, chest pain and disturbances in heart rhythm that quickly clear up. The agency is tracking nearly 800 reports, although not all have definitively been linked to the vaccines.
The C.D.C. advisers’ meeting comes as the Biden administration
