FDA reverses course, will review Moderna’s mRNA-based flu shot
Moderna revised its application to seek full approval for ages 50-64 and accelerated approval for 65+, aiming for FDA decision by Aug. 5 for 2026-27 flu season availability.
- The U.S. Food and Drug Administration on Feb 18, 2026 agreed to review Moderna's mRNA seasonal influenza vaccine after the company amended its application, reversing last week's refusal.
- The FDA's `refuse-to-file` decision stemmed from Dr. Vinay Prasad citing issues with the control vaccine and study design in a trial of about 41,000 people.
- Moderna proposed splitting approvals by age, seeking full approval for adults 50 to 64 and accelerated approval for adults 65 and older with a post-marketing study, while the FDA targets a decision by Aug. 5 for the 2026-2027 flu season.
- Shares of Moderna rose more than 5% after the news amid intense mRNA scrutiny by Robert F. Kennedy Jr., U.S. Health Secretary, who canceled $500 million funding.
- Regulators abroad are also reviewing the filing, with regulators in Europe, Canada and Australia assessing Moderna's vaccine while the company spent hundreds of millions and secured a $750 million Blackstone investment.
