Outcome Measures
Primary Outcomes (2)
1.Geometric Mean Titres (GMT) in Subjects After Receiving One Dose of Either QIVc, TIV1c or TIV2c
Immunogenicity of QIVc to comparator TIVc (For H1N1, H3N2 and B1 strain, the comparison is between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison is between QIVc and TIV2c) was assessed in terms of GMT in subjects measured by hemagglutination inhibition (HI) assay, three weeks after vaccination with one dose of either QIVc or TIV1c and TIV2c. Non-inferiority was established if the upper bound of the two-sided 95% confidence interval (CI) for the ratio of GMTs (GMT TIV1c or TIV2c /GMT QIVc) for HI antibody does not exceed the non-inferiority margin of 1.5.
Three weeks post vaccination (Day 22)
2. Percentages of Subjects Achieving Seroconversion After One Dose of Either QIVc, TIV1c or TIV2c
Immunogenicity of QIVc to comparator TIVc (For H1N1, H3N2 and B1 strain, the comparison is between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison is between QIVc and TIV2c) was assessed in terms of percentages of subjects showing seroconversion or significant increase in HI antibody titers, three weeks (day 22) after vaccination with one dose of either QIVc,TIV1c or TIV2c Seroconversion is defined in subjects seronegative at baseline (i.e., HI titer \<1:10 at Day 1) as post-vaccination HI titer ≥1:40, and defined in subjects sero-positive at baseline (i.e., HI titer ≥1:10 at Day 1) as a minimum of a 4-fold increase in post-vaccination HI titer
Three weeks post vaccination (Day 22)
Secondary Outcomes (11)
3. Percentages of Subjects Achieving Seroconversion After One Dose of Either QIVc, TIV1c or TIV2c in 18 to <65 and ≥ 65 Years Age Cohorts
Three weeks post vaccination (Day 22)
4. Percentages of Subjects Achieving HI Titer ≥1:40 After One Dose of Either QIVc, TIV1c or TIV2c in 18 to <65 and ≥ 65 Years Age-cohorts
Three weeks post vaccination (Day 22)
5.Geometric Mean Ratios (GMR) in Subjects After One Dose of Either QIVc, TIV1c or TIV2c in 18 to ≤60 Years and ≥ 61 Years Age Cohorts
Three weeks post vaccination (Day 22)
6. Percentages of Subjects Achieving Seroconversion After One Dose of Either QIVc, TIV1c or TIV2c in 18 to ≤60 Years and ≥ 61 Years Age Cohorts
Three weeks post vaccination (Day 22)
7. Percentages of Subjects Achieving HI Titer ≥1:40 After One Dose of Either QIVc, TIV1c or TIV2c in 18 to ≤60 Years and ≥ 61 Years Age Cohorts
