The primary purpose of the study is to assess the equivalence of the immune response elicited by two GSK Biologicals' adjuvanted influenza investigational vaccines (GSK2340272A and GSK2340274A) in adults aged 18 to 60 years. The second purpose of the study is to evaluate the safety and reactogenicity of these two vaccines.

Exclusion Criteria: - Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of the study vaccine or planned use during the study period. - Presence of evidence of substance abuse or of neurological or psychiatric diagnoses which, although stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports. - Presence of an axillary temperature >= 37.5°C (99.5°F), or acute symptoms greater than "mild" severity on the scheduled date of first vaccination. NOTE: The subject may be vaccinated at a later date, provided symptoms have resolved, vaccination occurs within the window specified by the protocol, and all other eligibility criteria continue to be satisfied. - Clinically or virologically confirmed influenza infection within 6 months preceding the study start. - Diagnosed with cancer, or treatment for cancer, within 3 years. - Any confirmed or suspected immunosuppressive or immunodeficient condition including history of human immunodeficiency virus (HIV) infection. - Clinically or virologically confirmed influenza infection within 6 months preceding the study start. - Chronic administration of immunosuppressants or other immune modifying drugs within 6 months of study enrolment or planned administration during the study period. - Receipt of any immunoglobulins and/or any blood products within 3 months of study enrolment or planned administration of any of these products during the study period. - Any significant disorder of coagulation or treatment with warfarin derivatives or heparin. - An acute evolving neurological disorder or history of Guillain-Barré syndrome. - Administration of any vaccines within 30 days before vaccination. - Any known or suspected allergy to any constituent of influenza vaccines; a history of anaphylactic-type reaction to any constituent of influenza vaccines; or a history of severe adverse reaction to a previous influenza vaccine. - Pregnant or lactating female - Female planning to become pregnant or planning to discontinue contraceptive precautions. - Any conditions which, in the opinion of the investigator, prevents the subjects from participating in the study. |
