WASHINGTON – The FDA says it plans to add a warning to COVID-19 MRNA vaccines about the risk of myocarditis and pericarditis.
Those terms refer to inflammation of the heart muscle and tissue surrounding the heart.
The Pfizer and Moderna vaccines are both MRNA vaccines.
This all comes after reports of inflammatory heart conditions among some young adults and teens who were recently vaccinated.
In general, the cases appeared to be rare and mild, and they resolved quickly.
Health experts emphasize that the benefits of MRNA COVID-19 vaccines outweigh the risks.
