Summary:

      Primary Objective:

      To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A,
      C, Y, and W following the administration of a single dose of Meningococcal Polysaccharide
      (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate Vaccine (MenACYW Conjugate vaccine)
      compared with those observed following the administration of a single dose of Meningococcal
      (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (Menactra®
      vaccine).

      Secondary Objective:

      Immunogenicity: To describe the antibody responses to the meningococcal serogroups A, C, Y,
      and W before and 30 days (+14 days) after vaccination with MenACYW Conjugate vaccine or
      Menactra®.

      Safety: To describe the safety profile of MenACYW Conjugate vaccine and that of Menactra®.

             study procedures.

        Exclusion criteria:

          -  Participant was pregnant, or lactating, or of childbearing potential (to be considered

             least 1 year, surgically sterile, or using an effective method of contraception* or
             abstinence from at least 4 weeks prior to vaccination until at least 4 weeks after
             vaccination).

             *Effective methods of contraception included oral contraception (pill), intrauterine
             device, or condoms used with spermicide.

          -  Participation in the 4 weeks preceding the study vaccination or planned participation
             during the present study period in another clinical study investigating a vaccine,
             drug, medical device, or medical procedure.

          -  Receipt of any vaccine in the 4 weeks preceding the study vaccination or planned
             receipt of any vaccine prior to Visit 2 except for influenza vaccination, which may be
             received at least 2 weeks before or after the study investigational vaccines. This
             exception includes monovalent pandemic influenza vaccines and multivalent influenza
             vaccines.

          -  Previous vaccination against meningococcal disease with either the study vaccine or
             another vaccine (i.e., mono- or polyvalent, polysaccharide, or Conjugate meningococcal
             vaccine containing serogroups A, C, Y, or W; or meningococcal B vaccine).

          -  Receipt of immune globulins, blood or blood-derived products in the past 3 months.

          -  Known or suspected congenital or acquired immunodeficiency; or receipt of
             immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy,
             within the preceding 6 months; or long-term systemic corticosteroid therapy
             (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).

          -  Moderate or severe acute illness/infection (according to Investigator judgment) on the
             day of vaccination or febrile illness (temperature greater than or equal to (>=) 99.5
             degree Fahrenheit or >= 37.5 degree Celsius). A prospective participant should not be
             included in the study until the condition had resolved or the febrile event had
             subsided.
