Historical H3N2 influenza virus HAI panel.

HAI assays were performed against a panel of historical influenza virus vaccine strains isolated from 1995 – 2016 with day 70 serum from vaccinated mice. The average log₂ geometric mean HAI serum antibody titers (GMTs) were determined for each group of mice (n = 5) and are presented in a heat map form. Colored cells represent groups that achieved a GMT ≥ 5.32, which correlates to an average antibody titer ≥ 1:40. Values closest to 5.32 are colored yellow and become a darker shade of green as the GMT value increases. Cells with no color represent groups that did not achieve a GMT ≥ 5.32.
