Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Fold Increase in Geometric Mean Titer (GMT)
Time Frame: Day 22/Day 1
|
GMT-fold increase - calculated as the GMT on Day 22 divided by the baseline GMT value
|
Day 22/Day 1
|
|
Seroconversion
Time Frame: Day 22 ± 2 days
|
Seroconversion rate was defined as the proportion of subjects with ≥4-fold increase in haemagglutination inhibition (HI) antibody titer and with a titer of ≥1:40
|
Day 22 ± 2 days
|
|
Seroprotection
Time Frame: Day 22 ± 2 days
|
Seroprotection rate, defined as the proportion of subjects with HI antibody titer ≥1:40
|
Day 22 ± 2 days
|
