From: Reproducible and later vaccine strain selection can improve vaccine match to A/H3N2 seasonal influenza viruses

A. Number of amino acid mutations in epitope sites difference relative to the dominant strain for the vaccine strain and reproducibly selected strains. B. Number of amino acid mutations in sites that have resulted in novel antigenic variants difference relative to the dominant strain for the WHO vaccine strain and reproducibly selected strains. C. Difference in antigenic distance to the dominant strain between the vaccine strain and the reproducibly selected strains. Pink bars indicate comparison between the dominant strain and the vaccine strain, blue bars indicate comparisons between the dominant strain and the reproducibly selected strain at WHO’s timing, and green bars indicate comparisons at delayed selection timing. Seasons for which comparison via antigenic cartography was not possible because HI tables could not be merged due to inconsistent labeling on antigens between 2004 and 2005, and differences in the species from which red blood cells were derived for the HI assay between 2007 and 2008 have been indicated with NA.
