Primary Outcome Measures:
  • Number of Participants With Solicited Injection Site and Systemic Adverse Events [ Time Frame: For 22 days ]
    Number of participants with injection site and systemic adverse events will be tabulated in its own, and by severity and day of onset. Described if solicited adverse event term is different from the PT.

  • Percentage of Participants With Seroprotection Rate of Hemagglutination Inhibition [HI] Antibody Titer [ Time Frame: Day 22 ]
    Seroprotection rate is measured by HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroprotection Rate was defined as the percentage of participants with HI antibody titer ≥ 40 for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain).

  • Seroconversion Rate of HI AntibodyTiter [ Time Frame: Day 22 ]
    Seroconversion rate is measured by HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroconversion Rate was defined as the perccentage of participants with a baseline HI antibody titer of ≥ 10 achieving a minimal 4-fold increase, or baseline HI antibody titer of < 10 achieving an HI antibody titer of ≥ 40 for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain).

  • Geometric Mean Fold Increase in HI Antibody Titer [ Time Frame: Day 22 ]
    Geometric mean fold increase in HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination, as compared to baseline.


Secondary Outcome Measures:
  • Change From Baseline in Blood Pressure [ Time Frame: Day 1 (Baseline), Day 8, Day 22 ]
    For continuous variables, summary statistics of measured values and respective changes from baseline will be calculated at each evaluation time point. In addition, figures illustrating individual changes will be created. For discrete variables, shift tables (before and after vaccination) will be created.

  • Change From Baseline in Safety Electrocardiogram (ECG) Parameters [ Time Frame: Day 1 and Day 22 ]
    The ECG data will be analyzed into 3 categories, `normal`, `abnormal but not clinically significant` and `abnormal clinically significant`. Using these variables, shift tables (before and after vaccination) will be created by individual participant. . The definitions for the acronyms are as follows: Within Normal Limits (WNL), Not Clinically Significant (NCS), and Clinically Significant (CS).

  • Geometric Mean Titer (GMT) of HI Antibody Titer [ Time Frame: Day 22 ]
    Geometric mean titer (GMT) of HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination

  • GMT of Single Radial Hemolysis (SRH) Antibody Titer [ Time Frame: Day 22 ]
    GMT of single radial hemolysis (SRH) antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination.

  • Seroprotection Rate of SRH Antibody Titer [ Time Frame: Day 22 ]
    Seroprotection rate is measured by SRH antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination.

  • Seroconversion Rate of SRH Antibody Titer [ Time Frame: Day 22 ]
    Seroconversion rate as measured by SRH antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination.

  • Geometric Mean Fold Increase in SRH Antibody Titer [ Time Frame: Day 22 ]
    Geometric mean fold increase in SRH antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination, as compared to baseline.
