Summary

Primary Objective:

  1. To describe the vaccine seroprotection (antibody titer≥1:8) to the antigens (meningococcal serogroups A, C, Y, and W) present in MenACYW conjugate vaccine or Menveo® measured by serum bactericidal assay using human complement (hSBA), for Groups 1 and 2 when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in Mexico
  2. To describe the vaccine seroprotection (antibody titer≥1:8) to the antigens (meningococcal serogroups A, C, Y, and W) present in MenACYW conjugate vaccine measured by hSBA, for Group 3, when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in the Russian Federation

Secondary Objective:

  1. To describe hSBA vaccine seroresponse to the antigens (meningococcal serogroups A, C, Y, and W) 30 days after the last vaccination of the infant series, when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in Mexico and Russian Federation (RF)
  2. To describe immunogenicity profile of routine pediatric vaccines when administered concomitantly with MenACYW conjugate vaccine or Menveo®; or when administered alone
  3. To describe hSBA antibody responses against meningococcal serogroups A, C, Y, and W when MenACYW conjugate vaccine and Menveo® are administered concomitantly with routine pediatric vaccines in Mexico and RF
  4. To describe antibody titers to the antigens present in MenACYW conjugate vaccine and Menveo®, before the first vaccination and 30 days after the last vaccination of the infant series and in the second year of life, when administered concomitantly with routine pediatric vaccines in a subset of subjects in Mexico and RF

Description

Study duration per participant is approximately 12 months
