Brief Summary
The primary safety objective of this study is to assess the safety of split- virion inactivated H1N1 vaccine with and without adjuvant when administered at the 7.5,15 or 30 mcg dose. The primary immunogenicity objective is to assess the antibody response following each dose of split- virion inactivated A(H1N1) vaccine with and without adjuvant. Participants will include up to 2200 healthy persons age 3 and older who have no history of novel influenza H1N1 2009 infection or novel influenza H1N1 2009 vaccination. This is a randomized, double-blinded, Phase II study in healthy males and non-pregnant females, aged 3 years and older. Subjects will be stratified by elders (equal to or more than 61 years), adults (18-60 years), adolescents (12-17 years) and children (3-11 years), elders and adolescents will be randomized into 5 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), children will be randomized into 4 dose groups (adjuvanted H1N1 vaccine of 7.5 or 15 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), adults will be randomized into 6 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose or placebo), 110 subjects per dose and age stratum will be to receive intramuscular influenza H1N1 vaccine. The H1N1 vaccine will be administered at Day 0 and Day 21. Following immunization, safety will be measured by assessment of adverse events through 21 days following the last vaccination (Day 42 for those receiving both doses), serious adverse events and new-onset chronic medical conditions through 6 months post the final vaccination (Day 180 after second vaccination), and reactogenicity to the vaccine for 8 days (Day 0-7) following each vaccination. Immunogenicity testing will be hemagglutination inhibiting (HAI) on serum obtained on the day 21 of each vaccination (prior to vaccination), on Day 21 after first vaccination, and 21 days following the second vaccination (Day 42).
