FDA Approves First mRNA Flu Vaccine for U.S. Adults Over 50
The Food and Drug Administration (FDA) has approved mFlusiva, the first mRNA-based influenza vaccine for adults in the United States. Developed by Moderna, the vaccine is approved for adults over 50, with accelerated approval for those aged 65 and over based on immune response data. The approval comes as mRNA technology, which was pivotal in COVID-19 vaccine development, is being adapted for flu vaccines to improve efficacy against emerging strains. The vaccine demonstrated a 26.6% higher effectiveness compared to traditional flu vaccines in recent trials. However, access for those over 65 is contingent on ongoing clinical trials assessing specific needs for this demographic.
