The U.S. FDA’s Vaccines and Related Biological Products Advisory Committee voted unanimously in favor of Moderna Inc.’s trivalent mRNA flu vaccine, mRNA-1010, which the company wants to brand as Mflusiva. On the question of whether the benefits of the product outweigh the risks in people ages 50 to 64, balloting was 9-0, and on whether the same is true in those 65 and older, the tally was again 9-0.
