Summary:

      The purpose of this study is to evaluate the long-term antibody persistence 6, 7, 8, 9 and 10
      years after receiving a primary vaccination of meningococcal conjugate vaccine MenACWY-TT
      versus Meningitec™ or Mencevax™ ACWY, and the safety and immunogenicity of a booster dose of
      MenACWY-TT administered 10 years after the primary vaccination. All subjects received a
      primary vaccination at 1 to 10 years of age in study 108658 (NCT00427908). No new subjects
      will be enrolled in this booster study.

             age at the time of enrollment will sign the informed consent form, even if the parent/
             LAR previously signed the ICF before the subject reached the legal age of consent.

          -  Healthy subjects as established by medical history and history-directed physical
             examination before entering into the study.

        All subjects must satisfy the following additional criteria prior to entry of the booster
        phase:

        suboptimal response during the persistence phase of the MenACWY-TT-027 study (i.e.
        MenACWY-TT-028, -029, -030, -031 and -032) are allowed to participate as they will be
