Primary Objective:
To demonstrate the non-inferiority of the seroprotection rate (serum bactericidal assay using human complement [hSBA] titer ≥ 1:8) to meningococcal serogroups A, C, W, and Y following the administration of a single dose of 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
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Meningococcal Infection (Healthy Volunteers) | Biological: Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate Vaccine MenACYW conjugate vaccine Biological: Meningococcal group A, C, W-135, and Y conjugate vaccine Biological: Human Papillomavirus 9-valent Vaccine 9vHPV Biological: Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed Combined with Inactivated Poliomyelitis Vaccine Tdap-IPV | Phase 3 |
The duration of study participation for each participant will be approximately 30 to 60 days, including 2 or 3 visits (1 or 2 vaccination visit) and 1 or 2 telephone calls, depending on study Group.
* This is the first dose of 9vHPV, of the 2-dose or 3-dose series according to the local recommendations and age of the participant. These additional vaccinations for the completion of 9vHPV schedule will take place outside of the objectives and scope of this study and thus will not be described in this protocol.
