Antigenic site B in influenza A virus hemagglutinin (HA) is immunodominant in circulating human H3N2 strains. Using deep mutational scanning, Wu et al. here define the local fitness landscapes of HA antigenic site B in six human H3N2 strains, providing insights into evolvability of influenza antigenicity.
