mRNA-based flu vaccine

Heard in 2 episodes across 2 shows since Aug 2026

An mRNA-based flu vaccine is a next-generation immunization technology that utilizes messenger RNA (mRNA) to instruct host cells to produce influenza-specific antigens, such as hemagglutinin, triggering a protective immune response. This platform offers significant advantages over traditional egg-based manufacturing, including rapid development cycles, precise strain matching, and the potential to combine multiple influenza and respiratory targets into a single formulation. Clinical candidates, such as Moderna's mRNA-1010 and Pfizer's modRNA candidates, have demonstrated strong immunogenicity and efficacy in late-stage clinical trials.
