Primary Outcome Measures
NameTimeMethod
Antibody Responses According to the Hemagglutinin Inhibition (HI) Assay After the First and Second VaccinationsDay 22, Day 29, Day 43, Day 202 and Day 387

HI antibody assay (used to assess immune responses in subjects following vaccination) according to the Center for Biologics Evaluation and Research (CBER) guidance for \<65 years of age: The lower bound of the two-sided 95% Confidence Interval (CI) for the percentages of subjects achieving seroconversion for HI antibody should be ≥ 40% and the lower bound of the two-sided 95% CI for the percentages of subjects achieving an HI antibody titer ≥ 1:40 should be ≥ 70%. Both criteria (seroconversion and HI antibody titer ≥ 40) had to be fulfilled to establish immunogenicity.

PPS Day 1-29 analysis set: N= 143, 149, 149, 146, 147, 147, 144, and 144 for Groups A, B, C, D, E, F,G,and H respectively.

Antibody Responses With and Without Seasonal Influenza Vaccination for Year 2009 to 2010.Day 22, Day 29, Day 43

HI antibody assay (used to assess immune responses in subjects following vaccination) according to the Committee for Medicinal Products for Human Use (CHMP) guidance: in adults ages 18 to 60 years are:The percentage of subjects with seroconversion or significant increase in HI antibody is \> 40%.The percentage of subjects achieving an HI titer ≥ 40 is \> 70% and The GMR is \> 2.5. All 3 criteria (seroconversion/significant increase, HI antibody titer ≥ 40, and GMR) had to be fulfilled to establish immunogenicity.Subgroup analysis based on receipt of recent seasonal vaccination.
