- 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.

Response rate for anti-HBsAg was defined as percentage of participants who achieved anti-HBsAg antibody concentrations \>=10 mIU/mL and \>=100 mIU/mL. Percentages are rounded off to the tenth decimal place.
Groups 1 and 2: Geometric Mean Concentrations (GMCs) of Pneumococcal Conjugate Vaccine (10-Valent, Adsorbed) (PCV10) Vaccine At 30 days post Dose 2 (4 MoA) and Dose 3 (12 to 18 MoA) GMCs of anti-pneumococcal antibodies was assessed by pneumococcal capsular polysaccharide (PnPS) Immunoglobulin G (IgG) ECL assay which was used to quantitate the amount of anti-streptococcus pneumoniae PS (serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F, and 23F) antibodies in human serum.
Groups 3 and 4: Geometric Mean Concentrations (GMCs) of Pneumococcal Conjugate Vaccine (13-Valent, Adsorbed) (PCV13) Vaccine Group 3: At 30 days post Dose 2 (4 MoA) and Dose 3 (12 to 18 MoA); Group 4: At 30 days post Dose 4 (12 to 18 MoA) GMCs of anti-pneumococcal antibodies was assessed by PnPS IgG ECL assay which was used to quantitate the amount of anti-streptococcus pneumoniae PS (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) antibodies in human serum.
Groups 1 and 2: Percentage of Participants With Response Rate >=0.35 mcg/mL for Pneumococcal Conjugate Vaccine (10-Valent, Adsorbed) PCV10 Vaccine At 30 days post Dose 2 (4 MoA) and Dose 3 (12 to 18 MoA) GMCs of anti-pneumococcal antibodies was assessed by PnPS IgG ECL assay which was used to quantitate the amount of anti-streptococcus pneumoniae PS (serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F, and 23F) antibodies in human serum. Percentages are rounded off to the tenth decimal place.
Groups 3 and 4: Percentage of Participants With Response Rate >=0.35 mcg/mL for Pneumococcal Conjugate Vaccine (13-Valent, Adsorbed) PCV13 Vaccine Group 3: At 30 days post Dose 2 (4 MoA) and Dose 3 (12 to 18 MoA); Group 4: At 30 days post Dose 4 (12 to 18 MoA) GMCs of anti-pneumococcal antibodies was assessed by PnPS IgG ECL assay which was used to quantitate the amount of anti-streptococcus pneumoniae PS (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) antibodies in human serum. Percentages are rounded off to the tenth decimal place.
Geometric Mean Concentrations (GMCs) of Anti-Measles, Mumps and Rubella (MMR) Antibodies Groups 1, 2 and 3: At 30 days post Dose 3 (12 to 18 MoA); Group 4: At 30 days post Dose 4 (12 to 18 MoA) GMCs of anti-measles and anti-rubella antibodies were measured by bulk IgG enzyme immunoassay (EIA) and anti-mumps antibodies were assessed by enzyme-linked immunosorbent assay (ELISA).
Percentage of Participants Who Achieved Vaccine Response for Measles, Mumps and Rubella (MMR) Antibodies Groups 1, 2 and 3: At 30 days post Dose 3 (12 to 18 MoA); Group 4: At 30 days post Dose 4 (12 to 18 MoA) GMCs of anti-measles and anti-rubella antibodies were measured by bulk IgG EIA and anti-mumps antibodies were assessed by ELISA. Vaccine response against anti-measles, anti-mumps, anti-rubella antibodies were defined as percentage of participants with anti-measles, anti-mumps, anti-rubella antibody concentration that met the respective mentioned criterion: measles: \>=255 mIU/mL; mumps: \>=10 mumps antibody units/mL and rubella: \>=10 IU/mL. Percentages are rounded off to the tenth decimal place.
