CEPI Puts Up to $54.3 Million Behind Moderna’s H5 mRNA Bird Flu Vaccine for Phase 3

The multilateral grant replaces canceled U.S. support.

Overview

  • CEPI’s commitment of up to $54.3 million will fund late-stage development of Moderna’s mRNA-1018, which the company says would be the first mRNA bird flu vaccine to enter a pivotal trial.
  • Phase 3 testing is planned for early 2026 in the United States and the United Kingdom, drawing on earlier immunogenicity data and results from Moderna’s seasonal flu program to support approval.
  • Under the agreement, Moderna will reserve 20% of production capacity for low- and middle-income countries with affordable pricing if an influenza pandemic occurs.
  • The program aligns with CEPI’s 100 Days Mission, emphasizing mRNA’s rapid design and manufacturing timelines compared with traditional egg- or cell-based influenza vaccines.
  • The funding shift follows HHS’s cancellation of a multihundred-million-dollar Moderna contract in May, as officials monitor increasing avian influenza activity with 71 human cases and two deaths reported and limited human-to-human spread.
