A phase I/II, open, controlled study in order to evaluate the reactogenicity and the immunogenicity of GlaxoSmithKline Biologicals influenza candidate vaccine containing the adjuvant AS25 (FluAS25) in an elderly population aged over 65 years (>65 years-old) previously vaccinated in 2004 with the same candidate vaccine in FLUAS25-001 clinical trial. For immunogenicity and safety evaluations, Fluarix™ (known as alpha-Rix™ in Belgium)vaccine will be used as reference. - FLUAS25-002

Exclusion Criteria

1. Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the administration of the study vaccine, or planned use during the study period.
2. Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the administration of the study vaccine.
