Text: Seroconversion (the percentage of subjects with either (a) a pre-vaccination HAI titer 10 and a post-vaccination HAI titer 40 or (b) a pre-vaccination titer 10 and a minimum four-fold rise in post-vaccination HAI antibody titer) in the TIV and rHA groups, respectively, was obtained in 66 % vs. 72 % for H1 ; 44 % vs. 61 % for H3 ; and 41 % vs. 41 % for B. Proportions achieving titers 40 were 96 % vs. 96 % for H1, 75 % vs. 85 % for H3, and 94 % vs. 93 % vs. B. Geometric mean titer ratios at day 28 (TIV/rHA) were 0. 77 for H1 ; 0. 58 for H3 ; and 1. 05 for B, respectively.
