My country is considered to be the cradle of the influenza virus pandemic strain and the new mutant strains of multiple [1]. The current influenza virus is still circulating in the crowd with H3N2 and H1N1 subtype and influenza B virus, the dominant strain is H3N2 subtype [2]. Therefore, it is necessary to understand the mutation dynamics of influenza A virus type 3. The authors respectively chicken anti-T3 polyclonal antibody and anti-hemagglutinin (H ...
