Cellular immune response to different influenza A (H3N2) virus strains with or without NGS at residue 144 in the globular head of HA. Humoral immune response to different influenza A (H3N2) virus strains with or without NGS at residue 144 in the globular head of HA evaluated by reverse genetics approach. The neutralizing ability of serum samples were evaluated by plaque reduction neutralization test. Statistical differences were calculated using a Mann–Whitney U test
