Outcome Measures

Primary Outcome Measures

  1. Antibody Responses After the First and Second Vaccinations [21 days after each vaccination]

    CBER guidance (<65 years of age): The lower bound of the two-sided 95% CI for the percent of subjects achieving seroconversion for HI antibody should be ≥ 40% AND the lower bound of the two sided 95% CI for the percent of subjects achieving an HI antibody titer ≥ 1:40 should be ≥ 70%.

  2. Number of Participants Reporting Solicited Local and Systemic Reactions After First Vaccination [Day 1 to 7]

    Safety was measured in terms of the number of participants reporting solicited local and systemic reactions after first vaccination.

  3. Number of Participants Reporting Solicited Local and Systemic Reactions After Second Vaccination [Day 22 to 28]

    Safety was measured in terms of the number of participants reporting solicited local and systemic reactions after second vaccination.

Secondary Outcome Measures

  1. Immunogenicity Measurement by Geometric Mean Titers (GMT) [21 days after each vaccination]

    Immunogenicity was measured in terms of the GMT at 21 days after each vaccination.

  2. Antibody Responses With and Without Seasonal Influenza Vaccination for Year 2009 to 2010 [Day 22 (three weeks after first vaccination); day 43 (three weeks after second vaccination)]

    Subgroup analysis based on receipt of recent seasonal vaccination. Comparison between subjects previously vaccinated versus not vaccinated with seasonal influenza vaccines.

  3. Geometric Mean Titers (GMTs) With and Without Seasonal Influenza Vaccination for Year 2009 to 2010 [Day 22 (three weeks after first vaccination); day 43 (three weeks after second vaccination)]

    Subgroup analysis based on receipt of recent seasonal vaccination. Comparison between subjects previously vaccinated versus not vaccinated with seasonal influenza vaccines.

  4. Antibody Response Based on Baseline Seropositivity [Day 22 (three weeks after first vaccination); day 43 (three weeks after second vaccination)]

    Subgroup analysis based on Subjects with a pre-vaccination HI antibody titer < 1:10 and prevaccination HI antibody titer ≥ 1:10

  5. Geometric Mean Titers (GMTs) Based on Baseline Seropositivity [Day 22 (three weeks after first vaccination); day 43 (three weeks after second vaccination)]

    Subgroup analysis based on Subjects with a pre-vaccination HI antibody titer < 1:10 and prevaccination HI antibody titer ≥ 1:10 Immunogenicity responses in subjects who are seropositive (A/H1N1 2009 HI titer ≥ 1:10) at Baseline (Day 1 (pre-vaccination)) as compared to those who are seronegative (HI titer < 1:10).

  6. Antibody Persistence by Geometric Mean Titers (GMT) [6 months (Day 202) and 12 months (Day 387) after second vaccination]

    Immunogenicity was assessed in terms of Geometric Mean Titers (GMT at 6 months (Day 202)and 12 months (Day 387) after second vaccination.

Time Frame Day 22 to 28

Outcome Measure Data

Analysis Population Description
The analysis was done on the safety set. Almost all the subjects across the vaccine groups received their first and second vaccinations within the protocol-specified window. While all the enrolled subjects received their first vaccination, 3% to 7% of subjects across the vaccine groups did not receive their second vaccination.

Adverse Events

Time Frame Throughout the entire study period. Five subjects received wrong vaccination according to the randomization and were excluded from PPS but were included in the safety set.
Adverse Event Reporting Description Local, systemic, and other reactions were collected from Study days 1 to 7 and 22 to 28. SAEs, medically attended visits, new onset of chronic diseases and AEs that lead to subject's withdrawal were collected from Day 1 (post-consent) through Day 387 (12 months following second vaccination).
