What to know

  • Moderna's mFlusiva is the first mRNA flu vaccine approved in the U.S., cleared for ages 50+ and available in pharmacies for the 2026 season.
  • The vaccine showed 27% greater efficacy than standard flu shots in clinical trials and can be manufactured faster to keep pace with evolving flu strains.
  • FDA approval for ages 65+ came via accelerated pathway with a required post-approval trial, after initial regulatory friction over Moderna's comparison methodology.
  • Pharmacies report patient confusion about age eligibility, vaccine differences, and whether mFlusiva also protects against Covid—it does not.

“It's like a temporary instruction to your immune system to alert your body's natural defense to recognize influenza.”

    mFlusiva reaches pharmacies; confusion emerges among patients

    As the mRNA flu shot becomes available in pharmacies, confusion arises about eligibility (ages 50+), efficacy comparisons with traditional shots, and whether it protects against Covid (it does not).

    “If you have not celebrated your 50th birthday, this vaccine should be of no interest to you.”

In June, the FDA's independent vaccine advisory panel unanimously recommended approval for adults 65 and older.
