Geometric Mean Titer
Time Frame: 3 weeks after vaccination (Day 22 ± 2 days)
|
GMT of HI antibodies and fold-increase in GMT (The primary endpoints are 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)
|
3 weeks after vaccination (Day 22 ± 2 days)
|
|
Seroprotection
Time Frame: 3 weeks after vaccination (Day 22 ± 2 days)
|
Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40 (The primary endpoints are 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)
|
3 weeks after vaccination (Day 22 ± 2 days)
|
|
Seroconversion
Time Frame: 3 weeks after vaccination (Day 22 ± 2 days)
|
Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40 (The primary endpoints are 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)
