Abstract: H9N2 is a low-pathogenic avian influenza subtype that has a significant impact on the global poultry industry.Since 1994,H9N2 has continuously mutated as a zoonotic pathogen in China,thus posing a severe threat to the poultry indus-try as well as human life and health.In particular,gene rearrangements and recombinations between H9N2 and other influenza viruses have increased the likelihood of avian influenza viruses crossing species barriers and infecting humans and other mam-mals,thereby posing new threats to global public health.Therefore,this article aims to provide a brief discussion of the epide-miology and vaccine research progress related to the H9N2 virus,serving as a valuable resource for safeguarding the economy of the poultry industry and global public health security.
