Immunogenicity - Geometric Mean Titer Fold Increase From Baseline
Tidsramme: 3 weeks after vaccination (Day 22 ± 2 days)
|
The primary endpoints were the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI).
These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997 and they were the following: 1. Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40, 2. Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40, 3. GMT of HI antibodies and fold-increase in GMT
