Moderna Inc. held a brief conference call to defend the safety of its Covid-19 shot from a barrage of questions about associated heart risks in young people.
Chief Medical Officer Paul Burton acknowledged on the call that the company’s vaccine does appear linked to increased chances of an inflammatory heart condition known as myocarditis in young men. Moderna maintains that the shot’s benefits continue to outweigh the extremely rare risk of myocarditis, he said Thursday.
