Safety and Immunogenicity of FluLaval™ TR and Fluarix® (Influenza Vaccines) in Young and Older Adults
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this trial is to describe the immunogenicity, the safety, and tolerability of FluLaval™ TR and Fluarix®, the latter serving as active comparator. The results will be compared to a standard immune response criteria, for both young and elderly populations.
Condition or disease
Biological: Influenza vaccine (A/H3N2, A/H1N1, and B strains)Biological: Fluarix
This randomized trial will assess the immune protection offered at Day 21 by FluLaval™ TR, Fluarix® being the comparator. In both groups, immune response will be assessed through a blood test before and 21 days following vaccination. The safety and tolerability of the study vaccine will be contrasted to the comparator vaccine over a period of 42 days following vaccination.
A Randomized, Double-Blind Trial Evaluating the Safety and Immunogenicity of an Influenza Vaccine With Reduced Preservative (FluLaval™ TR) and a Standard Influenza Vaccine (Fluarix®) in Subjects Between 18-60 and Over 60 Years of Age.
