Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Geometric Mean Titer Ratios of Antibodies to the GC3110B or GCFLU Quadrivalent Inj.
Time Frame: Day 0 (Pre-Vaccination) and Day 21 (Post-Vaccination)
|
Geometric mean titers of antibodies will be assessed using the hemagglutination inhibition (HI) assay.
|
Day 0 (Pre-Vaccination) and Day 21 (Post-Vaccination)

Percentage of Participants Achieving Pre-Defined Seroconversion Before and Following Vaccination
Time Frame: Day 0 (Pre-Vaccination) and Day 21 (Post-Vaccination)
|
Seroconversion is defined as either a pre-vaccination titer <1:10 and a post-vaccination titer ≥ 1: 40 or a pre-vaccination titer ≥ 1:10 and a ≥ 4-fold increase in post-vaccination titer 21 days after vaccination.
|
Day 0 (Pre-Vaccination) and Day 21 (Post-Vaccination)
|
|
Percentage of Participants Achieving Pre-Defined Seroprotection Before and Following Vaccination
Time Frame: Day 0 (Pre-Vaccination) and Day 21 (Post-Vaccination)
|
Antibodies will be assessed using the hemagglutination inhibition (HI) assay.
Seroprotection is defined as a titer ≥1:40 at pre-vaccination and 21 days after vaccination.
