Immunogenicity and Safety Study of a Quadrivalent Meningococcal Conjugate Vaccine Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers

Completed · Phase 3

Conditions studied: Healthy Volunteers (Meningococcal Infection)

In brief

The primary objective of this study is to demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO® when given concomitantly with routine pediatric vaccines to infants and toddlers 6 to 7 months of age and 12 to 13 months of age. The secondary objectives of the study are: * To demonstrate the non-inferiority of the percentage of participants with antibody titers to meningococcal serogroups A, C, Y, and W ≥ 1:8 following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO® when given concomitantly with pediatric routine vaccines to infants and toddlers at 6 to 7 months of age and 12 to 13 months of age. * To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days after the second vaccination at 12 to 13 months of age with MenACYW conjugate vaccine or MENVEO®. * To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days and 6 months after the first vaccination at 6 to 7 months of age with MenACYW conjugate vaccine or MENVEO®. * To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days after the second vaccination at 20 to 23 months of age with MenACYW conjugate vaccine or Menactra®.

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 serogroup-containing vaccine)
• For subjects to be enrolled at 6 to 7 months of age (Group 1 and Group 2), prior receipt of more than 2 doses of rotavirus vaccine (Rotateq), DTaP, Hib, IPV, pneumococcal, hepatitis B (for children who received hepatitis B at 2 and 4 months of age, prior receipt of more than 3 doses of hepatitis B vaccine)
• For subjects to be enrolled at 6 to 7 months of age (Group 1 and Group 2), receipt of the 2 doses of rotavirus vaccine at 2 and 4 months of age
