Over 1,000 cases of heart inflammation have been detected in recipients of Moderna’s COVID-19 vaccine who are under 40 years old, the biotechnology company said on June 10.
Myocarditis, a type of heart inflammation, has been most prevalent following vaccination in males 18 to 24 years old, according to the company. In a document (pdf) filed before upcoming meetings with U.S. regulators and an advisory panel, Moderna said 42.6 cases of myocarditis have appeared per million second doses administered to males in that age group across the world.
