Messenger RNA-Based Flu Vaccine Makes Its Debut in U.S. Pharmacies: Who Can Get It?
Moderna's mRNA-based flu vaccine, mFlusiva, is now available at U.S. pharmacies for adults 50+. FDA approved it, with Phase 3 trials showing 27% higher efficacy than standard vaccines. Priced around $171 per dose, coverage by insurers is uncertain. The vaccine targets flu only, not COVID-19.
