Detailed Summary
This study is designed to assess the safety and immunogenicity of a single dose of Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (SP284) to support registration of the product in Japan. Primary Objective: * To describe the seroprotection rate \[% of subjects with serum bactericidal assay using baby rabbit complement (SBA-BR) ≥1:128\] to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age Secondary Objectives: * To describe the safety following receipt of SP284 vaccine in subjects 2 through 55 years of age * To describe the immune responses to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age.
