The vaccine uses a novel nanoparticle platform (CoPoP) to deliver precise amounts of H5 and N1 proteins, achieving 100% protection in preclinical mouse trials against the deadly 2.3.4.4b H5N1 variant. Unlike current approved vaccines, this recombinant protein approach doesn't require eggs for manufacturing, potentially enabling faster production and adaptation to evolving bird flu strains resistant to existing vaccines.
