Brief Summary:
The purpose of the study was to evaluate immune lot consistency of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine and the immune non-inferiority compared to the licensed vaccine Menactra®, and describe the safety and additional immunogenicity of these study vaccines in adolescents and adults 10 to 55 years of age in the United States (US).
Primary Objectives:
- To demonstrate the immune lot consistency of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine with respect to serum bactericidal assay using human complement (hSBA) geometric mean titers (GMTs).
- To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra®.
Secondary Objective:
- To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adult population (18 to 55 years old).
- To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adolescent population (10 to 17 years old).
- To compare the hSBA vaccine seroresponses of meningococcal serogroups A, C, Y, and W for each of 3 lots of MenACYW Conjugate vaccine 30 days (+14 days) after vaccination.
- To compare the hSBA antibody GMTs of meningococcal serogroups A, C, Y, and W following the administration of MenACYW Conjugate vaccine to those observed following the administration of Menactra®.
Observational Objectives:
- To describe the safety profile of MenACYW Conjugate vaccine and that of the licensed Menactra®.

Healthy meningococcal-vaccine naïve adolescents and adults were randomized and received a single dose of either MenACYW Conjugate vaccine from 1 of the 3 lots (Lot 1, Lot 2, or Lot 3) or Menactra®. They were assessed for immunogenicity at baseline (pre-vaccination) and at 30 to 44 days post-vaccination. Safety information were collected post-vaccination and throughout the entire study.

Primary Outcome Measures :
