H1N1 vaccine of 15 μg HA on Day 0 and 21
H1N1 vaccine of 7.5 μg HA on Day 0 and 21
Arm Description
15 μg HA (0.5 mL) per injection, 2 injections 50 children (aged over 3 years old to 6 years old) and 50 children/teenagers (aged over 6 years old to 18 years old) were assigned to receive two injections of H1N1 vaccine 3 weeks apart
7.5 μg HA (0.25 mL) per injection, 2 injections 50 toddlers (aged over 1 year old to 3 years old) were assigned to receive two injections of H1N1 vaccine 3 weeks apart
Outcomes
Primary Outcome Measures
The primary immunogenicity objective is to assess the antibody response following a single dose of study vaccine, grouped by age of recipient, when administered at the 7.5 or 15 μg HA doses.
The primary safety objective of this study is to assess the safety of the study vaccine when administered at the 7.5 or 15 μg HA doses.
Secondary Outcome Measures
The secondary immunogenicity objective is to assess the antibody response following 2 doses of study vaccine, grouped by age of recipient, when administered at the 7.5 or 15 μg HA doses.

5. Study Description
Brief Summary
This is a laboratory-blinded study in healthy toddlers, children, and teenagers designed to investigate the safety, reactogenicity, and immunogenicity of an inactivated influenza H1N1 vaccine (AdimFlu-S). There are 3 age strata, and each contains at least 50 subjects: greater than or equal to 1 year to less than 3 years, greater than or equal to 3 years to less than 6 years, and greater than or equal to 6 years to less than 18 years. In each age strata, all eligible subjects received 2 injections of AdimFlu-S (A/H1N1) at a designated dosage level (7.5 μg, 15 μg and 15 μg for 1~<3, 3~<6 and 6~<18 years, respectively) at 3 weeks apart.
Following immunization, safety is measured by assessment of adverse events for 6 weeks following the first vaccination, serious adverse events and new-onset chronic medical conditions through 7 months post first vaccination, and reactogenicity to the vaccines for 7 days following each vaccination. Immunogenicity testing includes hemagglutination inhibition (HAI) testing on serum obtained before first vaccination, and three and six weeks after first vaccination.
