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

United States950 participantsStarted 2018-10-04

Plain-language summary

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®.
