A(H1N1)pdm09-specific HI antibody responses stratified by the participants' history of seasonal influenza vaccination. The graphs shown represent the GMTs (A, D), SCRs (B), and SPRs (C) with 95% CIs determined following vaccination with the AS03-adjuvanted or nonadjuvanted A(H1N1)pdm09 (H1N1) vaccine. Data are stratified by the participants' history of seasonal influenza vaccination (Flu/No flu). The GMTs in study A are also stratified by age (D). Dotted lines represent the cutoffs of the CHMP criteria for the HI antibody responses in adults 18 to 60 years of age with respect to the SCR (>40%) and SPR (>70%). Data for time zero (day 0) and days 21 and 42 were reported previously (6) and are shown here for completeness. y, years.
