Primary Outcome Measures
NameTimeMethod
Immunogenicity Results After Each Vaccination by Vaccine Group, in Participants 18 to 64 Years of Age21 days after each vaccination

Seroconversion is defined by CBER (Center for Biologics Evaluation, Research and Review) as the percentage of participants with either a prevaccination HI titer \<1:10 and a post vaccination HI titer \> 40 or a pre-vaccination HI titer \> 10 and a minimum four-fold rise in post-vaccination HI antibody titer. Seroprotection is defined as participants having HI antibody titer ≥1:40.

Immunogenicity Results After Each Vaccination by Vaccine Group, in Participants ≥65 Years of Age21 days after each vaccination

Seroconversion is defined by CBER as the percentage of participants with either a prevaccination HI titer \<1:10 and a post vaccination HI titer \> 40 or a pre-vaccination HI titer \> 10 and a minimum four-fold rise in post-vaccination HI antibody titer. Seroprotection is defined as participants having HI antibody titer ≥1:40.

Secondary Outcome Measures
NameTimeMethod
Geometric Mean HI Titer by Vaccine Groups; in Participants 18 to 64 Years of Age and ≥65 Years of Age21 days after each vaccination

Geometric mean hemagglutinin inhibition (HI) titer = GMT

Number of Subjects With Seroconversion and With HI ≥1:40, in Participants ≥61 Years of Age21 days after each vaccination

Immunogenicity evaluation after each vaccination by vaccine group according to CHMP criteria. Seroconversion is defined as the percentage of participants with either a prevaccination HI titer \<1:10 and a post vaccination HI titer \> 40 or a pre-vaccination HI titer \> 10 and a minimum four-fold rise in post-vaccination HI antibody titer. Seroprotection is defined as Hemagglutinin Inhibition (HI) antibody titer ≥1:40.

Number of Participants Reporting Solicited Local and Systemic Reactions After the First Vaccination, in Participants 18 to 64 Years of Age7 days after vaccination

Solicited local and systemic reactions that occurred within 7 days after the day of vaccination were used as indicators of reactogenicity.

Number of Participants Reporting Solicited Local and Systemic Reactions After the Second Vaccination, in Participants 18 to 64 Years of Age7 days after vaccination

Solicited local and systemic reactions that occurred within 7 days after the day of vaccination were used as indicators of reactogenicity.

Number of Participants Reporting Solicited Local and Systemic Reactions After the Second Vaccination, in Participants ≥65 Years of Age7 days after vaccination

Solicited local and systemic reactions that occurred within 7 days after the day of vaccination were used as indicators of reactogenicity.

Number of Subjects With Seroconversion and With HI ≥1:40, in Participants 18 to 60 Years of Age21 days after each vaccination

Immunogenicity evaluation after each vaccination by vaccine group according to CHMP (Committee for Medicinal Products for Human Use) criteria. Seroconversion is defined as the percentage of participants with either a prevaccination HI titer \<1:10 and a post vaccination HI titer \> 40 or a pre-vaccination HI titer \> 10 and a minimum four-fold rise in post-vaccination HI antibody titer. Seroprotection is defined as Hemagglutinin Inhibition (HI) antibody titer ≥1:40.

Geometric Mean Ratio From Baseline, in Participants 18 to 60 Years of Age and ≥61 Years of Age21 days after vaccination

Immunogenicity evaluation after each vaccination by vaccine group according to CHMP criteria. Geometric Mean Ratio (GMR) of the hemagglutinin inhibition (HI)titers.

Number of Participants Reporting Solicited Local and Systemic Reactions After the First Vaccination, in Participants ≥65 Years of Age7 days after vaccination

Solicited local and systemic reactions that occurred within 7 days after the day of vaccination were used as indicators of reactogenicity.
