Safety and Immunogenicity of FluLaval™ TR and Fluarix® (Influenza Vaccines) in Young and Older Adults

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.
