US found link between vaccines and cases of inflammation in adolescents and young adults, but say benefits outweigh risks.
The US Food and Drug Administration will add a warning to the Covid vaccines produced by Pfizer/BioNTech and Moderna about rare cases of heart inflammation in adolescents and young adults, the agency announced on Wednesday.
US Centers for Disease Control and Prevention advisory groups, meeting to discuss reported cases of the heart condition after vaccination, found the inflammation in adolescents and young adults is likely linked to the vaccines, but that the benefits of the shots appeared to clearly outweigh the risk.
The CDC said that patients with heart inflammation after vaccination generally recover from the symptoms and do well.
Moderna said it is aware of reports of heart inflammation cases following administration of mRNA vaccines.
