WASHINGTON (Al Jazeera) – The U.S. Food and Drug Administration (FDA) has added a warning about the risk of heart inflammation to fact sheets for Moderna and Pfizer-BioNTech COVID-19 vaccines.
The warning on Friday noted that reports of adverse events following vaccination – particularly after the second dose – suggest increased risks of myocarditis, or inflammation of the heart muscle, and pericarditis, or inflammation of the tissue surrounding the heart.
The warning update follows an extensive review of information and discussion by the U.S. Centers for Disease Control and Prevention (CDC’s) Advisory Committee on Immunization Practices meeting on Wednesday, the FDA said.
At end of the second week of June, more than 1,200 cases of myocarditis or pericarditis have been reported to the U.S. Vaccine Adverse Event Reporting System.
The cases appear to be notably higher in males and in the week after the second vaccine dose. The CDC identified 309 hospitalizations from heart inflammation in persons under the age of 30, of which 295 have been discharged.
There has been no comment from Pfizer and Moderna yet.
