Clinical Scorecard: FDA to Review Moderna's mRNA Influenza Vaccine Following Recent Developments

At a Glance

Key Highlights

• FDA initially issued a 'refusal to file' letter due to trial design concerns regarding comparator vaccines for adults 65 and older.
• Moderna's 40,000-person trial showed higher effectiveness in adults 50+ compared to a standard flu shot.
• Moderna seeks full approval for ages 50-64 and accelerated approval for 65+, with a post-market study planned.
