This study identifies key HA residues driving antigenic diversity in H5Nx avian influenza viruses through serology and in silico analysis, highlighting four significant residues for vaccine design.

This study evaluates HA functionality of UK H5N1 avian influenza viruses from 2020-2022, finding they retain strong avian phenotype with low zoonotic threat.

This paper identifies an H9N2 avian influenza virus mutant with a G149E mutation in HA that loses haemagglutination activity but retains replication fitness, highlighting challenges for vaccine and surveillance efforts.
