Brief Summary
Primary Objective: To demonstrate the non-inferiority of the seroprotection rate (serum bactericidal assay using human complement \[hSBA\] titer greater than or equal to \[\>=\] 1:8) to meningococcal serogroups A, C, W, and Y following the administration of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate vaccine (MenACYW Conjugate vaccine) (Group 1) compared to a single dose of Nimenrix® (Group 2). Secondary Objective: To describe:
- the antibody response of meningococcal serogroups A, C, W, and Y measured by hSBA, before and 1 month following meningococcal vaccination administered alone (Groups 1 and 2) or concomitantly with 9-valent human papilloma virus (9vHPV) and tetanus, diphtheria, and acellular pertussis - inactivated polio vaccine \[adsorbed, reduced antigen(s) content\] (Tdap-IPV) vaccines (Group 3).
- the antibody response of meningococcal serogroup C measured by hSBA and serum bactericidal assay using baby rabbit complement (rSBA), before vaccination and at Day 31 after vaccination with MenACYW Conjugate vaccine or Nimenrix® (Groups 1 and 2) according to MenC primed status.
- the antibody response against antigens of 9vHPV and Tdap-IPV vaccines, before and 1 month following vaccination.
- the safety profile in each group after each and any vaccination.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Antibody Titers >=1:8 Against Meningococcal Serogroups A, C, W, and Y Measured by hSBA Following Vaccination With MenACYW Conjugate Vaccine or Nimenrix® Vaccine (Non-inferiority Analysis): Groups 1 and 2
Antibody titers against meningococcal serogroups A, C, W, and Y were measured by serum bactericidal assay using human complement (hSBA). Non-inferiority data analysis for this outcome measure was planned to be conducted only for Groups 1 and 2, not for Group 3. Group 3 data is reported separately.

- Masking Details
- The study was performed in a partially observer-blind fashion: In Groups 1 and 2 * Investigators and study staff who conducted the safety assessment, participants, parents/legally acceptable representatives, the Sponsor, and laboratory personnel performing the serology testing were kept blinded to the vaccine received. * Only the study staff who prepared and administered the vaccine and were not involved with the safety evaluation know which vaccine was administered. In Group 3 \- Everyone involved in the study (i.e., Investigator, study staff, the Sponsor, participants, parents/legally acceptable representatives) know which vaccine was administered. This open-label design for Group 3 was due to the different vaccination schedule for this group than for Groups 1 and 2.
