Abstract
The present disclosure discloses a whole avian-origin reverse genetic system, a recombinant H5N2 subtype avian influenza virus, a vaccine containing the virus, and a preparation method and application thereof. The genome of the recombinant virus is comprised of a modified HA gene derived from a highly pathogenic H5N6 subtype avian influenza virus strain, as well as PB2, PB1, PA, NP, NA, M and NS genes derived from H5N2 subtype avian influenza D7 virus strain. The recombinant virus is a recombinant H5N2 avian influenza virus rescued from the D7 virus strain as a backbone, which is an avirulent virus strain with the original immunogenicity, and can maintain a high virus titer during the chick embryo culture process. The recombinant virus fully meets the biological safety requirements and has a good application prospect.
