Clinical Trial Summary

This open label randomized study will be conducted to evaluate and/or describe the immunogenicity and describe the safety of MenACYW conjugate vaccine when administered in infants and toddlers. It will be conducted in India and the RSA in 2 cohorts: - Cohort I: Infants and toddlers 6 months to 16 months of age - Cohort II: Infants and toddlers 6 weeks to 15 months of age In Cohort I, eligible participants will be randomized in a 1:1 ratio to receive 2 intramuscular (IM) injections (1+1 vaccination schedule) of either MenACYW conjugate vaccine (Groups 1 and 3) or Menactra vaccine (Groups 2 and 4), co-administered with routine pediatric vaccines. In Cohort II, eligible participants will be randomized in a 2:1 ratio to receive either 3 IM injections (2+1 vaccination schedule) of MenACYW conjugate vaccine co-administered with routine pediatric vaccines (Groups 5 and 7) or routine pediatric vaccines only (Groups 6 and 8). The primary objectives of this study are: - To demonstrate the non-inferiority of immunogenicity of 2 doses of MenACYW conjugate vaccine compared to 2 doses of Menactra® vaccine in infants and toddlers 6 months to 16 months of age in terms of serum bactericidal assay using human complement (hSBA) seroprotection (titers ≥ 1:8) in India and the Republic of South Africa (RSA) - To demonstrate the vaccine immune sufficiency of 3 doses of MenACYW conjugate vaccine in infants and toddlers 6 weeks to 15 months of age in terms of hSBA seroprotection (titers ≥ 1:8) in India and the RSA The secondary objectives of this study are: - To describe the antibody titers to the meningococcal serogroups A, C, Y, and W: - before and 30 days post primary series of MenACYW conjugate vaccine and before and 30 days post booster dose of MenACYW conjugate vaccine in infants and toddlers 6 weeks to 15 months of age in India and the RSA when administered concomitantly with other age-recommended vaccines. - before and after 30 days post each dose of MenACYW conjugate vaccine or Menactra vaccine in infants and toddlers 6 months to 16 months of age in India and the RSA when administered concomitantly with other age-recommended vaccines. - To describe the antibody responses against the antigens of the other age-recommended vaccines when administered concomitantly with MenACYW conjugate vaccine: - in infants and toddlers 6 weeks to 15 months of age in India and the RSA. - in infants and toddlers 6 months to 16 months of age in India and the RSA. The duration of each participant's active participation in the study will be approximately 10 to 11 months for Cohort I and 13,5 to 14,5 months for Cohort II.
