Phase 3
Completed
Conditions
Healthy Volunteers (Meningococcal Infection)
Interventions
Biological: Meningococcal polysaccharide (serogroups A,C,Y and W) tetanus toxoid Conjugate vaccine
Biological: Meningococcal group B vaccine
Biological: Diphtheria, tetanus, pertussis (acellular component), hepatitis B, poliomyelitis (inactivated) vaccine

Biological: Pneumococcal 13-valent polysaccharide conjugate vaccine
Registration Number

Lead Sponsor

Brief Summary

The primary objective of the study was to demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, W, and Y (MenACYW) in terms of serum bactericidal assay using human complement (hSBA) vaccine seroprotection (antibody titer greater than or equal to \[\>=\] 1:8) when MenACYW Conjugate vaccine was administered concomitantly with Bexsero® in the second year of life compared to when MenACYW Conjugate vaccine was given alone.

The secondary objectives were to compare the hSBA antibody response in terms of geometric mean titers (GMTs) against meningococcal serogroups A, C, W, and Y when MenACYW Conjugate vaccine was administered concomitantly with Bexsero® or when MenACYW Conjugate vaccine was given alone in the second year of life; to describe the hSBA and serum bactericidal assay using baby rabbit complement (rSBA) antibody responses against meningococcal serogroups A, C, W, and Y before and after the 1st dose of MenACYW Conjugate vaccine administered at 3 months of age, before and after the 2nd dose of MenACYW Conjugate vaccine administered at 12 to 13 months of age for Group 1 and Group 2; to describe the hSBA and rSBA antibody persistence against meningococcal serogroups A, C, W, and Y after the 1st dose of MenACYW Conjugate vaccine administered at 3 months of age for Group 1 and Group 2.

A solicited reaction (SR) was defined as an "expected" adverse reaction (AR) (sign or symptom) observed and reported under the conditions (nature and onset) pre-listed (i.e., solicited) in the protocol and case report form (CRF) and considered as related to vaccination. Solicited injection site reactions included injection site tenderness, injection site erythema, and injection site swelling and were planned to be collected and reported for each vaccine separately; and not planned to be collected for Rotavirus vaccine as the vaccine was administered orally, and no injection site reactions were expected to occur. Reported AEs for each arm were presented as pre-specified in the study protocol. Here, '0' in number analyzed field for MenACYW categories signifies that no participant was evaluable because in Group 3 MenACYW vaccine was not administered.
