Overview

  • The combined mRNA-1083 vaccine demonstrated immune responses at least as strong as, and in some cases superior to, separate COVID-19 and flu vaccines in adults over 50.
  • Phase III trial results, involving approximately 8,000 participants, were published in the Journal of the American Medical Association on May 7, 2025.
  • The vaccine showed a stronger immune response against influenza A, comparable response against influenza B, and at least equal response to SARS-CoV-2 compared to existing vaccines.
  • No serious adverse events were observed, with mild side effects similar to those of standard individual vaccines.
  • Regulatory approval, strain adaptation, and a recommendation from Germany’s Ständige Impfkommission (Stiko) are required before the vaccine can be widely deployed, with no confirmed rollout timeline yet.
