Immunogenicity and safety of a quadrivalent meningococcal tetanus toxoid-conjugate vaccine (MenACYW-TT) in ≥56-year-olds: A Phase III randomized study.

Background: Invasive meningococcal disease has a high mortality rate in individuals aged ≥56 years, but no vaccine is currently licensed in the USA for this age group. This study assessed the safety and immunogenicity of an investigational quadrivalent meningococcal tetanus toxoid conjugate vaccine (MenACYW-TT) compared with a meningococcal quadrivalent polysaccharide vaccine (MPSV4) in this age group.

Methods: This was a Phase III, modified double-blind, randomized, non-inferiority study (NCT02842866) across 35 clinical sites in the USA and Puerto Rico in individuals aged ≥56 years.
