E.2.2 | Secondary objectives of the trial |
To evaluate for superiority in GMT HI titer first after one dose and second after two doses of the 3.75 μg and 7.5 μg A/H1N1 2009 groups adjuvanted with MF59 as compared to the unadjuvanted 7.5 μg and 15 μg A/H1N1 2009 groups
• To evaluate whether the 3.75 μg, and 7.5 μg A/H1N1 2009 groups with MF59 adjuvant are non-inferior in GMT as compared to the unadjuvanted 7.5 μg and 15 μg A/H1N1 2009 groups first after one dose and second after two doses. To evaluate each A/H1N1 2009 vaccine candidate HI assay results first after one dose and second after two doses according to immunogenicity criteria defined by CHMP recommendations. To evaluate immunogenicity responses according to seasonal influenza vaccination status within the past 12 months.• To evaluate immunogenicity responses in subjects who are seropositive (A/H1N1 2009 HI titer ≥ 1:10) at Baseline (Day 1) as compared to those who are seronegative (HI titer < 1:10)
• To evaluate antibody persistence at Day 202 and Day 387. |
