Overview
Brief Summary
The purpose of this study was to evaluate the antibody response to each of the four influenza vaccine strains included in the study vaccine, as measured by hemagglutination inhibition (HAI) at 4 weeks after the last dose of the study vaccine in young subjects aged between 3 years old and 17 years old.

Outcomes
Primary Outcomes
Evaluate the immunogenicity profiles for influenza virus vaccine strains of the AdimFlu-S (QIS) by seroconversion rate
Time Frame: Change from baseline for anti-hemaglutinin antibodies at 28 days post immunization
The primary endpoint of immunogenicity evaluation was the seroconversion rate
Evaluate the immunogenicity profiles for influenza virus vaccine strains of the AdimFlu-S (QIS) by geometric mean folds increase
Time Frame: Change from baseline for anti-hemaglutinin antibodies at 28 days post immunization
The primary endpoint of immunogenicity evaluation was the geometric mean folds increase
Secondary Outcomes
- Evaluate the immunogenicity profiles for influenza virus vaccine strains of the AdimFlu-S (QIS) by seroprotection rate(Change from baseline for anti-hemaglutinin antibodies at 28 days post immunization)
- Evaluate the safety and tolerability profiles including the presence or absence of the pre-specified reactogenicity events and other serious/non-serious adverse events of the AdimFlu-S (QIS)(In regard to the long term safety of the study vaccine, the significant and/or serious adverse event(s) will be recorded during the 6 months follow up after the scheduled last vaccination)
