Safety, and Immunogenicity of Two Influenza Vaccines in Healthy Subjects 3 to 64 Years Old
A Phase III, Observer-Blind, Randomized, Controlled, Multicenter Study to Evaluate Safety, Tolerability, and Immunogenicity of Two Trivalent Subunit Inactivated Influenza Vaccines in Healthy Children Aged 3 to 8 Years, in Healthy Children/Adolescents Aged 9 to 17 Years,and in Healthy Adults Aged 18 to 64 Years

Brief Summary
This protocol is designed to evaluate safety, clinical tolerability and immunogenicity of the 2007 southern hemisphere formulation of a Novartis conventional influenza vaccine licensed in the EU and many other worldwide countries, according to the US FDA Draft Guidance for Industry "Clinical data needed to support the licensure of trivalent inactivated influenza vaccine", issued in March 2006, and to evaluate safety, clinical tolerability and immunogenicity of the 2007 southern hemisphere formulation of a Novartis conventional influenza vaccine already licensed in US. The purpose of the control arm is primarily to provide a comparative assessment for safety, not immunogenicity or effectiveness.

Outcome Measures
Primary Outcomes (2)
Percentage of Subjects With Seroprotection, in Healthy Adults 18 to 64 Years of Age
To evaluate immunogenicity, measured by seroprotection (percentage of subjects achieving a hemagglutination inhibition \[HI\] titer ≥40) after one injection of the investigational influenza virus vaccine, administered to healthy adults 18 to 64 years of age. The CBER Guidance states that the lower bound of the two-sided 95% CI for the percentage of subjects achieving seroprotection meet or exceed 70%.
21 days after vaccination
Percentage of Subjects Achieving a Seroconversion Rate, in Adults 18 to 64 Years of Age
Seroconversion rate is defined as percentage of subjects achieving seroconversion (defined as negative pre-vaccination serum \[HI\<10\]/ post-vaccination HI titer ≥40) or significant increase defined as at least a 4-fold increase). According to the CBER Guidance, the lower bound of the two-sided 95% CI for the percentage of subjects achieving seroconverion/significant increase meet or exceed 40%.
21 days after vaccination

ACTIVE COMPARATORInterventions
Two intramuscular injections of the investigational influenza virus vaccine administered 4 weeks part to group 3 to 8 years of age while one injection was administered to groups 9 to 17 years of age and 18 to 64 years of age.
Two intramuscular injections were administered 4 weeks apart to group 3 to 8 years of age while one injection was administered to groups 9 to 17 years of age and 18 to 64 years of age.
