Exclusion criteria
Exclusion criteria: - Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period. - Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs during thestudy period. (For corticosteroids, this will mean prednisone, or equivalent, >= 0.5 mg/kg/day. Inhaled and topical steroids are allowed.) - Any chronic drug therapy to be continued during the study period. - Planned administration/ administration of a vaccine not foreseen by the study protocol within one month of the study vaccine dose. - Previous vaccination against meningococcal disease of serogroup A, C, W-135 or Y. - Previous vaccination against tetanus within the last 6 months. - History of meningococcal disease. - Known exposure to N. meningitidis of serogroup A, C, W-135 or Y within previous 12 months. - Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection. - A family history of congenital or hereditary immunodeficiency. - History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. - Major congenital defects or serious chronic illness. - History of any neurologic disorders or seizures. - Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever.

| Main Objective: To evaluate the immune response induced by four different formulations of GSK Biologicals’ MenACWY-TT candidate conjugate vaccine versus MENCEVAX™ ACWY in healthy adolescents/young adults aged 15-19 years.;Secondary Objective: To evaluate the safety and reactogenicity of four different formulations of GSK Biologicals’ MenACWY-TT candidate conjugate vaccine versus MENCEVAX™ ACWY in healthy adolescent/young adults aged 15-19 years;Primary end point(s): One month after the vaccine dose, in all subjects: - Percentage (%) of serum bactericidal activity SBA-MenA, SBA-MenC, SBA-MenW-135 and SBA-MenY responders.* *A responder is defined as a subject having a greater than or equal to a 4-fold increase in SBA titer from pre to post vaccination. | — |
