Brief Summary
The purpose of the study is to evaluate different doses of the Influenza A/H1N1 pandemic vaccine in adults and the elderly. Primary Objectives:
- To describe the immunogenicity of the candidate vaccines after a single injection.
- To describe the safety of the candidate vaccines after a single injection.

Outcome Measures
Primary Outcomes (8)
Number of Participants With Detectable Antibodies Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age 18 to 64 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay. Detectable anti HA antibody titer was defined as titers ≥ 10 (1/dilution) on Day 0 and Day 21 post-vaccination.
Day 0 and Day 21 post-vaccination
Number of Participants With Seroprotection Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age 18 to 64 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay. Seroprotection was defined as a titer ≥ 40 (1/dil).
Day 0 and Day 21 post-vaccination
Geometric Mean Titers (GMTs) of A/H1N1 Antibodies Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age 18 to 64 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay.
Day 0 and Day 21 post-vaccination
Number of Participants With Detectable Antibodies Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age ≥ 65 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay. Detectable anti-HA antibody titer was defined as titers ≥ 10 (1/dil).
Day 0 and Day 21 post-vaccination
Number of Participants With Seroprotection Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age ≥ 65 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay. Seroprotection was defined as a titer ≥ 40 (1/dil).
Day 0 and Day 21 post-vaccination
Geometric Mean Titers (GMTs) of A/H1N1 Antibodies Before and Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age ≥ 65 Years
Antibodies to vaccine were measured using the Hemagglutinin Inhibition (HAI) assay.
Day 0 and Day 21 post-vaccination
Number of Participants Reporting a Solicited Injection Site or Systemic Reaction Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age 18 to 64 Years
Solicited Injections Site Reactions: Pain, Erythema, Swelling, Induration, and Ecchymosis. Solicited Systemic Reactions: Fever (Temperature), Headache, Malaise, Myalgia, and Shivering
Day 0 up to Day 7 post-vaccination
Number of Participants Reporting a Solicited Injection Site or Systemic Reaction Following Vaccination With Either Adjuvanted or Non-adjuvanted A/H1N1 Pandemic Vaccine or a Placebo: Age ≥ 65 Years
Solicited Injections Site Reactions: Pain, Erythema, Swelling, Induration, and Ecchymosis. Solicited Systemic Reactions: Fever (Temperature), Headache, Malaise, Myalgia, and Shivering.
Day 0 up to Day 7 post-vaccination
