As influenza vaccine efficacy is reported to be lower in elderly subjects compared to healthy adults, probably as a result of immunosenescence, there is a desire to devise ways to increase the current vaccines efficacy for this target population. Adjuvants are known to boost immune responses, thus representing one way to increase the efficacy of the current GlaxoSmithKline Fluarix™ influenza vaccine in elderly subjects. The purpose of this study is to evaluate the immunogenicity and the reactogenicity of a vaccination with four different adjuvanted GlaxoSmithKline influenza vaccines administered to elderly subjects. For immunogenicity and safety evaluations, healthy adults aged 18 to 40 years old and elderly aged 65 years and older will receive Fluarix™ and form the control groups of this trial.

Official Title: Demonstrate the Non-inferiority in Term of Cellular Mediated Immune Response of GSK Biologicals' Influenza Candidate Vaccines Containing Various Adjuvants Administered in Elderly Population (Aged 65 Years &Amp; Older) vs Fluarix™ (Known as Alpha-Rix™ in Belgium) Administered in Adults (18-40 Years)

Primary Outcome Measures:
  • To demonstrate the non inferiority 21 d post-vaccination of the influenza adjuvanted vaccines administered in elderly subjects (aged 65 y and older) [ Time Frame: 21 days post vaccination ] [ Designated as safety issue: No ]
  • as compared to Fluarix™ administered in adults (aged 18-40 y) in terms of cellular mediated immune response. [ Time Frame: 21 days post vaccination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the safety and reactogenicity of vaccination with adjuvanted influenza vaccines during 21 d following the intramuscular administration of the vaccine [ Time Frame: 21 days post vaccination ] [ Designated as safety issue: No ]
  • in elderly subjects (aged 65 y and older). Fluarix will be used as reference. [ Time Frame: 21 days post vaccination ] [ Designated as safety issue: No ]
  • To evaluate the humoral immune response (anti-haemagglutinin titre) 21,90 and 180d after vaccination with influenza adjuvanted candidate vaccines. [ Time Frame: 21, 90 and 180 days post vaccination ] [ Designated as safety issue: No ]
