Study to Evaluate Reactogenicity and Immunogenicity of Revaccination With Adjuvanted Influenza Vaccine in Elderly

February 22, 2018 updated by: GlaxoSmithKline

A Phase II, Open, Controlled Study to Evaluate the Reactogenicity and the Immunogenicity of GlaxoSmithKline Biologicals' Adjuvanted Influenza Vaccine in Elderly Adults Previously Vaccinated With Either Fluarix™ or the Adjuvanted Vaccine.

Since influenza vaccines are normally administered every year because of the frequent change in their antigenic composition, the safety and immunogenicity profile of adjuvanted influenza vaccine need to be re-evaluated after repeated vaccine administration. In this study, subjects previously vaccinated with Fluarix or the influenza adjuvanted vaccine, will receive a booster dose with the 2006-2007 season's formulations of either Fluarix or the adjuvanted vaccine.
