       Mutations driving bird flu vaccine escape identified
       Haemagglutinin residues shape antigenic diversity in H5 avian
       influenza viruses and influence vaccine effectiveness.
       May 5, 2026
       While vaccination remains a key strategy for controlling avian
       influenza in poultry and reducing the risk of zoonotic
       transmission to humans, the virus evolves rapidly, often leading
       to mismatches between vaccine strains and circulating field
       viruses. These differences can weaken vaccine protection and
       enable the virus to escape immune responses.
