Safety and Immunogenicity of an Adjuvanted Trivalent Influenza Vaccine in Children 6 to <72 Months of Age in Mexico.
A Phase 3, Observed-Blind, Randomized, Multi-center Study to Evaluate Safety and Immunogenicity of an Adjuvanted Trivalent Influenza Vaccine in Children 6 to <72 Months of Age in Mexico.
The administration of adjuvanted Trivalent Influenza Vaccine (aTIV) has come to result in a more immunogenic and effective response compared with conventional influenza vaccines in elderly and adults.
The aim of this study is to evaluate safety and immunogenicity of Novartis aTIV in children 6 to <72 months of age, Mexican population, in comparison to Fluzone, a non-adjuvanted trivalent influenza vaccine (TIV).

Antibody response was assessed in terms of GMTs in all three homologous virus strains, 21 days after last immunization, in subjects 6 to <72 months of age. The study is considered a success if the 21 days after last immunization GMT ratios of aTIV relative to TIV demonstrate as non-inferior with the lower limit (LL) of the two sided 95% confidence interval (CI) above 0.67 (-0.176 on log10 scale) for each vaccine strain (Center for Biologics Evaluation and Research {CBER} Guideline on Seasonal Vaccines May 2007). |
