Summary

This Phase III, open-label, randomized, parallel-group, active-controlled, multicenter study was conducted to assess the immunogenicity and safety of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine when administered alone and in combination with other pediatric vaccines in healthy toddlers in South Korea, Thailand, the Russian Federation, and Mexico. Primary Objective: * To describe the immunogenicity profile of MenACYW Conjugate vaccine administered alone or concomitantly with licensed pediatric vaccine(s) (measles-mumps-rubella vaccine [MMR] + Varicella, diphtheria, tetanus, acellular pertussis, hepatitis B, poliomyelitis, and Haemophilus influenzae type-b Conjugate vaccine [DTaP-IPV-HB-Hib], or pneumococcal Conjugate vaccine [PCV13]). Secondary Objective: * To describe the immunogenicity profile of licensed pediatric vaccine(s) (MMR + Varicella, DTaP-IPV-HB-Hib, or PCV13) when administered alone or concomitantly with MenACYW Conjugate vaccine.

Eligibility Criteria

Inclusion Criteria

  • For South Korea: Korean males and females aged 12 to 23 months on the day of the first study visit.
  • For Mexico: Males and females aged 12 to 23 months on the day of the first study visit.
  • For the Russian Federation: Males and females aged 12 to 14 months or 16 to 23 months on the day of the first study visit (eligible for enrollment to MenACYW Conjugate vaccine group) or 15 to 23 months on the day of the first study visit (eligible for enrollment to the MenACYW Conjugate vaccine positive(+) PCV13 group or the PCV13 group).
  • For Thailand: Thai males and females aged 12 to 23 months on the day of the first study visit
  • Participants had received all recommended standard of care vaccinations according to their age as per local regulations*.
  • For the Russian Federation only, participants aged 15 to 23 months on the day of the first study visit (eligible for enrollment to MenACYW Conjugate vaccine+PCV13 group or the PCV13 group) must not had received the third PCV13 vaccination corresponding to his or her age as per the country's National Immunization Program (NIP). The 2nd dose of PCV13 must had been administered at least 4 weeks before the 3rd dose of PCV13 was administered in the study.
  • For South Korea, participants must not had received the MMR or Varicella vaccination corresponding to his or her age at inclusion.
  • For Mexico, participants must not had received the DTaP-IPV-HB-Hib vaccination corresponding to his or her age at inclusion.
  • For Thailand, participants must not have received the any dose of MMR or V vaccination.
  • Informed consent form was signed and dated by the parent(s) or guardian if allowed by local regulations (and by independent witnesses if required by local regulations)†.
  • Participant and parent/guardian were able to attend all scheduled visits and to comply with all trial procedures.
  • *Participants must had received the total number of doses expected for each vaccine recommended for his/her age in the respective NIPs, but inclusion of participants with variations in the vaccine administration timeframes is considered acceptable if the total number of doses for the corresponding vaccines had been completed (e.g., in Mexico, 3 infant doses of the pentavalent vaccine must had been administered but the 4th dose due in the 2nd year of life should not had been administered for participants to be included in the trial). For the Russian Federation only, participants that had not received a seasonal flu vaccination from 6 months of age according to the Russian NIP were still eligible to participate in this study. For Thailand only, participants who had received a vaccine ahead of the schedule can still be included in the study provided the first doses of MMR and Varicella vaccines have not been administered prior to inclusion.
  • †In the Russian Federation, as per local regulations, only the participant's parent(s) are entitled to sign an informed consent form. A child under the responsibility of a guardian were not included in the study.

Exclusion Criteria

  • Participation in the 4 weeks preceding the first trial vaccination or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure.
  • Receipt of any vaccine in the 4 weeks (28 days) preceding the first trial 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 trial 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).
  • For participants enrolled at sites in the Russian Federation: previous vaccination with the third dose of
