  • Outcome Measures

    Primary Outcome Measures

    1. Seroprotection [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)

    2. Seroconversion [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)

    3. Geometric Mean Titer [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)

    Secondary Outcome Measures

    1. Number of Participants With Local and Systemic Adverse Events, as a Measure of Safety and Tolerability [Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 days)]

      Solicited local and systemic AEs, Unsolicited AEs Unsolicited AEs were collected from baseline (Day 1) to 3 weeks after vaccination (Day 22 ± 2 days). Solicited local and systemic AEs were collected by subjects diary from Day 1 (day of vaccination) to Day 4
