Immunogenicity and Safety of a Quadrivalent Meningococcal Conjugate Vaccine in Infants and Toddlers When Administered Concomitantly With Routine Pediatric Vaccines in the United Kingdom

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.

    Time frame: 30 days post-vaccination at the age of 12 to 13 months (i.e., at the age of 13 to 14 months)

    Antibody titers of Meningococcal Serogroups A, C, Y, and W were measured by rSBA assay. Percentage of participants with rSBA antibody titers distribution <1:4, >=1:4, >=1:8, >=1:16; >=1:32; >=1:64, >=1:128, >=1:256; >=1:512; >=1:1024; >=1:2048; >=1:4096; >=1:8192; >=1:16384; >=1:32768 for meningococcal serogroups A, C, Y, and W were reported in this outcome measure.

  38. Geometric Mean Titers of Antibodies Measured by hSBA Against Meningococcal Serogroups A, C, Y, and W: Group 1 and 2 - PPAS2

    Time frame: 30 days post-vaccination at the age of 3 months (i.e., at the age of 4 months) and before vaccination at the age of 12-13 months

    GMTs of antibody against meningococcal serogroups A, C, Y, and W were measured by hSBA. Titers were expressed in terms of 1/dilution.

  39. Percentage of Participants With hSBA Antibody Titers >=1:4 and >=1:8 Against Meningococcal Serogroups A, C, Y, and W - PPAS2

    Time frame: 30 days post-vaccination at the age of 3 months (i.e., at the age of 4 months) and before vaccination at the age of 12-13 months

    Antibody titers of Meningococcal Serogroups A, C, Y, and W were measured by hSBA assay. Percentage of participants with hSBA antibody titers >=1.4 and >=1:8 for meningococcal serogroups A, C, Y, and W were reported in this outcome measure.

  40. Geometric Mean Titers of Antibodies Measured by rSBA Against Meningococcal Serogroups A, C, Y, and W: Group 1 and 2 - PPAS2

    Time frame: 30 days post-vaccination at the age of 3 months (i.e., at the age of 4 months) and before vaccination at the age of 12-13 months

    GMTs of antibody against meningococcal serogroups A, C, Y, and W were measured by rSBA. Titers were expressed in terms of 1/dilution.

  41. Percentage of Participants With rSBA Antibody Titers >=1:8 and >=1:128 Against Meningococcal Serogroups A, C, Y, and W - PPAS2

    Time frame: 30 days post-vaccination at the age of 3 months (i.e., at the age of 4 months) and before vaccination at the age of 12-13 months

    Antibody titers of Meningococcal Serogroups A, C, Y, and W were measured by rSBA assay. Percentage of participants with rSBA antibody titers >=1:8 and >=1:128 for meningococcal serogroups A, C, Y, and W were reported in this outcome measure.

  42. Number of Participants With Solicited Injection Site Reactions After Any Vaccination

    Time frame: Within 7 days post any vaccination

    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.

  43. Number of Participants With Solicited Systemic Reactions After Any Vaccination

    Time frame: Within 7 days after any vaccination

    A SR was an expected AR (sign or symptom) observed and reported under the conditions (nature and onset) prelisted (i.e., solicited) in the CRB and considered as related to the product administered. Solicited systemic reactions included fever, vomiting, crying abnormal, drowsiness, appetite lost, and irritability. Reported AEs for each arm were presented as pre-specified in the study protocol.
