Filter by:This study is conducted to support a 2-dose series (1+1 vaccination schedule) for immunization of individuals from 6 months of age. The study is designed to evaluate the non-inferiority of the immunological response of MenACYW conjugate vaccine to Nimenrix® after the completion of the 2-dose series (1+1 vaccination schedule), with the first dose (priming dose) being given at 6-7 months of age to MenACWY- naïve healthy infants and the second dose (booster dose) given at 12-13 months of age. This study will also describe additional immunogenicity parameters and safety of MenACYW conjugate vaccine and Nimenrix® in the same population of participants.
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.
Primary Objective: - To describe the safety profile of the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines in healthy adults, adolescents, toddlers and infants, when administered alone (Stages 1-4) or concomitantly with MenQuadfiTM (MenACYW conjugate vaccine) (for Stages 2-4 only), and with age-appropriated routine pediatric vaccines (for Stages 3-4 only) 1. To describe the safety profile of the SP MenB vaccine formulations, Bexsero Vaccine and Trumenba Vaccine in healthy adults, and adolescents; 2. To describe the safety profile of the SP MenB vaccine formulations and Bexsero Vaccine in toddlers and infants; 3. To describe the safety profile of the SP MenB vaccine formulations, - when administered alone - when administered with MenQuadfiTM (MenACYW conjugate vaccine) - when administered with routine infant immunizations - To describe the immune response to the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines after the last dose of primary vaccination in healthy adults, adolescents, toddlers and infants, when administered alone, or concomitantly with MenQuadfi Vaccine or other routine vaccines, as measured by the serum bactericidal assay using human complement (hSBA) in the primary panel of MenB strains by Stage, by age group and by vaccine schedule Secondary Objective: - To describe the immune response to the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines at each timepoint in healthy adults, adolescents, toddlers and infants, when administered alone or concomitantly with MenQuadfi Vaccine or other routine vaccines as measured by hSBA in the primary panel of MenB strains by Stage by age group and by vaccine schedule - To describe the immune response (breadth of coverage) in the secondary panel of MenB strains in participants (adults and adolescents) in Stage 1 and 2 after the last dose of the primary series in each group - To describe the persistence of immune response following primary series at D366, and immune response 1 month after a booster dose of the SP MenB vaccine given 1-year post-dose 1 (at D366) in a subset of adults and adolescents in Stage 2 who received SP MenB vaccine formulations, Bexsero Vaccine or Trumenba Vaccine as measured by hSBA in the primary panel of MenB strains by age group - To describe the immune response against meningococcal serogroups A, C, W and Y measured with hSBA in participants from each agegroup receiving MenQuadfi Vaccine
Primary Objective: To demonstrate the non-inferiority of the seroprotection rate (serum bactericidal assay using human complement [hSBA] titer greater than or equal to [>=] 1:8) to meningococcal serogroups A, C, W, and Y following the administration of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate vaccine (MenACYW Conjugate vaccine) (Group 1) compared to a single dose of Nimenrix® (Group 2). Secondary Objective: To describe: - the antibody response of meningococcal serogroups A, C, W, and Y measured by hSBA, before and 1 month following meningococcal vaccination administered alone (Groups 1 and 2) or concomitantly with 9-valent human papilloma virus (9vHPV) and tetanus, diphtheria, and acellular pertussis - inactivated polio vaccine [adsorbed, reduced antigen(s) content] (Tdap-IPV) vaccines (Group 3). - the antibody response of meningococcal serogroup C measured by hSBA and serum bactericidal assay using baby rabbit complement (rSBA), before vaccination and at Day 31 after vaccination with MenACYW Conjugate vaccine or Nimenrix® (Groups 1 and 2) according to MenC primed status. - the antibody response against antigens of 9vHPV and Tdap-IPV vaccines, before and 1 month following vaccination. - the safety profile in each group after each and any vaccination.
