Brief Summary
Primary objective: This study aimed to demonstrate the non-inferiority of the antibody response against meningococcal serogroups A, C, Y, and W following the administration of a 3-dose series of MenACYW conjugate vaccine compared to a 3-dose series of a licensed meningococcal vaccine when each vaccine was given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b \[DTaP-IPV-HB-Hib vaccine\]) to infants and toddlers 6 weeks to 18 months old Secondary objectives: This study aimed to demonstrate the non-inferiority of the antibody (Ab) response against meningococcal serogroups A, C, Y, and W following the administration of 2 doses in infancy of MenACYW conjugate vaccine compared to 2 doses of a licensed meningococcal vaccine when each vaccine was given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and DTaP-IPV-HB-Hib vaccine) to infants and toddlers 6 weeks to 18 months old. \- This study aimed to describe the Ab responses against meningococcal groups A, C, Y, and W and the antigens of the routine pediatric vaccines administered in the study.

- Modified double blind for Groups 1 and 2 and open label for Groups 3 and 4 for meningococcal vaccines. Open-label for all concomitant routine vaccines. Modified double-blind: the participants parent / legally acceptable representative, the Investigator, and other study personnel remain unaware of the treatment assignments throughout the trial. An unblinded vaccine administrator will administer the appropriate vaccines but will not be involved in safety data collection.
