Moderna Says COVID Vaccine Has Fewer Breakthrough Cases Than Pfizer, but Higher Myocarditis Rates in Young Men

- Moderna defended the use of its Covid vaccine, saying the protection it offers against severe disease, hospitalization and death outweighs the risk of myocarditis.
- Reported cases of the rare heart inflammation in men under 30 are relatively higher after Moderna’s vaccine compared with Pfizer’s, said Chief Medical Officer Dr. Paul Burton.
- However, he also touted data from the CDC that showed the rates of mild or severe disease from Covid were lower in Moderna recipients.
