Age-stratified A(H1N1)pdm09-specific HI antibody responses. The GMTs (A), SCRs (B), and SPRs (C) with 95% CIs determined following vaccination with AS03-adjuvanted or nonadjuvanted A(H1N1)pdm09 (H1N1) vaccine containing 3.75 or 15 μg of HA are shown. Dotted lines represent the cutoffs of the CHMP criteria for HI antibody responses in adults 18 to 60 years of age with respect to the SCR (>40%) and SPR (>70%). The data for time zero (day 0) and days 21 and 42 supplement previously published data for the cohorts without age stratification (6). y, years.
