US to add heart inflammation warning for COVID-19 mRNA vaccines for teens

US health authorities plan to update official guidance about administering mRNA COVID vaccines to adolescents and young adults after finding a likely link to rare cases of heart inflammation, but say the overall benefits still “clearly” outweigh the risks.

The decision was announced during a meeting of experts convened by the Centers for Disease Control and Prevention that reviewed 323 confirmed instances of inflammation of the lining surrounding the heart among people under 30 following vaccination.

A pediatrician at Cohen Children’s Medical Center in New York and member of the expert panel said, “Fortunately it’s an extraordinarily rare event, and when the event happens it’s generally quite mild.”

He added he would continue to strongly advise parents to vaccinate their adolescents.

The cases are predominantly among males, most occur after the second dose, and there are no confirmed deaths.
