The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of one dose of four different formulations of the MenACWY conjugate vaccine when given to healthy subjects aged 15-19 years. The selection of the best formulation will be based on data obtained up to one month after the vaccine dose.
Condition or disease
Biological: Meningococcal Vaccine
The study is open. However, the 4 different formulations of GSK's MenACWY conjugate vaccine will be administered in a double-blind manner. Mencevax™ ACWY vaccine will serve as active control. Subjects will receive one vaccine dose only (GSK's MenACWY conjugate vaccine or Mencevax™ ACWY vaccine), and will have 2 blood samples taken, before and one month after vaccination.
A Primary Vaccination Study to Assess the Immunogenicity, Safety & Reactogenicity of 1 Dose of 4 Different Formulations of GSK Biologicals' Meningococcal Conjugate Vaccine (MenACWY) vs 1 Dose of MENCEVAX™ ACWY in Healthy Subjects Aged 15-19 Years

Percentage of serum bactericidal activity SBA-MenA, SBA-MenC, SBA-MenW-135 and SBA-MenY responders (i.e. 4-fold increase in serum bactericidal antibody [SBA] titre from pre to post vaccination) at 1 month after the first vaccine dose
Secondary Outcome Measures
Antibodies to MenACWY before + 1 m after dose 1, 12 m after dose 1 in control + with selected vaccine groups, 1 m after booster
