Non-Inferiority of Meningococcal Vaccine GSK134612 Versus Mencevax™ in 11-17 Year-Old Subjects
Primary Vaccination Study in Subjects Aged 11-17 Years to Demonstrate the Non-inferiority of GSK Biologicals' Meningococcal Vaccine GSK134612 Vaccine Versus Mencevax™ ACWY
The purpose of this study is to demonstrate, in 11-17 year old subjects, the non-inferiority of meningococcal vaccine GSK134612 compared to licensed meningococcal vaccine Mencevax™.

Multicentre study with 2 treatment groups. Each subject will have 2 blood samples taken for immunogenicity analyses, one prior to vaccination and one taken 30 days later.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
