Oct 10, 2026 · 12m

Summary

Dr. Anna Durbin discusses the first season of the mRNA flu vaccine, noting it uses the same strains as traditional vaccines due to regulatory timelines. She explains that side effects like fever stem from the lipid nanoparticle delivery system and highlights how the dissolution of the ACIP committee has complicated insurance coverage. Durbin also warns that reduced U.S. investment in mRNA technology risks falling behind global competitors in future pandemic preparedness.
