The U.S. Food and Drug Administration (FDA) approves the first messenger RNA (mRNA) vaccine for seasonal flu. According to multiple reports, the decision follows the agency’s earlier refusal to move forward with the company’s approval request. Both outlets describe that the FDA initially rejected the application earlier in the year, and later reversed course, ultimately approving an mRNA-based shot intended for seasonal influenza. Live Science and the Washington Times both focus on the regulatory sequence, highlighting that the approval represents a milestone for mRNA vaccine technology in flu prevention in the United States. The reports do not dispute the basic timeline: an initial FDA decision against reviewing the request or rejecting it, followed by a subsequent approval. The information presented is centered on the FDA’s actions and the novelty of the vaccine platform for seasonal flu, rather than on clinical results or broader implications beyond the approval itself.
