Hide Description Antibody titers against meningococcal serogroups A, C, Y, and W were measured by serum bactericidal assay using human complement (hSBA). The hSBA vaccine seroresponse was defined as a post-vaccination hSBA titer greater than or equal to (>=) 1:16 for participants with pre-vaccination hSBA titer less than (<) 1:8, or a >= 4-fold increase in hSBA titer from pre-vaccination to post-vaccination for participants with pre-vaccination hSBA titer >= 1:8.
