Numbers represent the number of animals from each group that achieved an antibody titer ≥1:40 in the (top table) and ≥1:80 (bottom table) against 13 historical H3N2 vaccine strains. Colors range from red representing 0 animals achieving the designated titer to dark green representing when all 8 animals surpassed the antibody titer cutoff.
