Outcome Measures
Primary Outcome Measures
- Immunogenicity Endpoint: The Geometric Mean Titer (GMT) and GMT Ratio for the Four Strains Included in the Vaccine, Non-inferiority Analysis. [Day 22]
The GMT of the post-vaccination (Day 22) hemagglutination inhibition (HI) titer. The GMT ratio was defined as the GMT for aTIV-1 (or aTIV-2) over the GMT for aQIV for all of the four strains.
- Immunogenicity Endpoint: The Difference Between the Seroconversion Rate (SCR) for the Four Strains Included in the Vaccine, Non-inferiority Analysis [Day 22]
The SCR is defined as the percentage of subjects with either a pre-vaccination HI titer < 1:10 and a post-vaccination HI titer >= 1:40 or a pre-vaccination HI titer >= 1:10 and a >= 4-fold increase in post-vaccination HI titer. The SCR Difference is defined as the difference between the SCR of post- vaccination (Day 22) HI titer for aTIV-1 (or aTIV-2) and the SCR of post-vaccination (Day 22) HI titer for aQIV. aTIV-1 and aTIV-2 vaccine groups are pooled for the analysis of A-H1N1 and A-H3N2 strains. For B/Victoria TIV=TIV-1. For B/Yamagata TIV=TIV-2.
- Immunogenicity Endpoint: The Percentage of Subjects Achieving SCR for Hemagglutination Inhibition (HI) Antibody for the Four Strains Included in the Vaccine. [Day 22]
The percentage of subjects vaccinated with aQIV achieving SCR at Day 22 was assessed for each of the 4 strains. SCR was defined as the percentage of subjects with either a pre-vaccination HI titer <1:10 and a post-vaccination HI titer ≥1:40 or a pre-vaccination HI titer ≥1:10 and a ≥4-fold increase in post-vaccination HI titer. Assessment criteria was considered fulfilled if the lower bound of the two-sided 95% confidence interval for the percentage of subjects achieving SCR for HI antibody should meet or exceed 30%.
- Immunogenicity Endpoint: The Percent of Subjects Achieving an HI Antibody Titer ≥ 1:40 for the Four Strains Included in the Vaccines. [Day 22]
The percentage of subjects vaccinated with aQIV achieving HI antibody titers ≥ 1:40 at Day 22 was assessed for each of the 4 strains. Assessment criteria was considered fulfilled if the lower bound of the two-sided 95% confidence interval for the percentage of subjects achieving a post-vaccination HI antibody titer ≥ 1:40 should meet or exceed 60%.
Secondary Outcome Measures
- Immunogenicity Endpoint: Geometric Mean Titers (GMT) Against Homologous Strains [Day 1 and Day 22]
For the assessment of GMTs using HI assay, aTIV-1 and aTIV-2 vaccine groups were pooled for the analysis of A-H1N1 and A-H3N2 strains. aTIV-1 and aTIV-2 vaccine groups are pooled for the analysis of A-H1N1 and A-H3N2 strains. For B-Victoria TIV=aTIV-1. For B-Yamagata TIV=aTIV-2. The immunologic superiority in HI antibody responses for the alternate B strain (eg, the influenza B strain included in the aQIV but not in the aTIV formulation) were assessed for each aTIV separately, using the GMT ratio (aTIV/aQIV) at Day 22.
- Immunogenicity Endpoint: Geometric Mean Ratio (GMR) of Post Vaccination HI Titer Over the Pre-vaccination HI Titer Against Homologous Strains [Day 22/Day 1]
The GMR was assessed as the postvaccination HI titer divided by the prevaccination HI titer (Day 22/Day 1). aTIV-1 and aTIV-2 vaccine groups were pooled for the analysis of A-H1N1 and A-H3N2 strains. For B-Victoria TIV=aTIV-1. For B-Yamagata TIV=aTIV-2.
- Immunogenicity Endpoint: The Percentage of Subjects With a Titer ≥1:40 Against Homologous Strains [Day 1 and Day 22]
The percentage of subjects with HI titer of ≥1:40 at Day 1 (prevaccination) and Day 22 (postvaccination) was assessed for homologous strains. aTIV-1 and aTIV-2 vaccine groups are pooled for the analysis of A-H1N1 and A-H3N2 strains. For B/Victoria TIV=TIV-1. For B/Yamagata TIV=TIV-2.
- Immunogenicity Endpoint: The Percentage of Subjects With SCR Against Homologous Strains [Day 22]
The SCR was defined as the percentage of subjects with either a prevaccination HI titer <1:10 and a postvaccination HI titer ≥1:40 or a prevaccination HI titer ≥1:10 and a ≥4-fold increase in postvaccination HI titer. For assessment if SCR using HI assay, aTIV-1 and aTIV-2 vaccine groups were pooled for the analysis of A-H1N1 and A-H3N2 strains. For B-Victoria TIV=aTIV-1. For B-Yamagata TIV=aTIV-2. The immunologic superiority in HI antibody responses for the alternate B strain (eg, the influenza B strain included in the aQIV but not in the aTIV formulation) were assessed for each aTIV separately, using the difference in SCR (aTIV-aQIV) at Day 22.
- Safety Endpoint: Number of Subjects With Solicited Local and Systemic Adverse Events (AEs) Following Vaccination [Day 1 through Day 7]
Safety of vaccination was assessed in terms of percentage of subjects reporting solicited AEs up to 7 days after vaccination.
- Safety Endpoint: Number of Subjects With Unsolicited AEs [Day 1 through Day 22]
Safety of vaccination was assessed in terms of percentage of subjects reporting unsolicited AEs up to 21 days after vaccination.
- Safety Endpoint: Number of Subjects With Serious AEs (SAEs), AEs Leading to Withdrawal From the Study, New Onset of Chronic Diseases (NOCDs) and AEs of Special Interest (AESIs) [Day 1 through Day 181]
Safety of vaccination was assessed in terms of percentage of subjects reporting SAEs, AEs leading to withdrawal, NOCDs, and AESIs and medically attended AE up to 180 days after vaccination.
