摘要

Laboratory staff who work with meningococcal isolates are at increased risk for developing invasive disease relative to the general population. This was the first study of laboratory workers who received both a conjugate vaccine against meningococcal serogroups A, C, W-135, and Y (Men ACWY-CRM, Menveo) and an investigational multicomponent vaccine against serogroup B containing factor H binding protein, neisserial adhesin A, Neisseria heparin binding antigen, and New Zealand strain outer membrane vesicles (4CMenB). Healthy adults (18 to 50 years of age) received three doses of 4CMenB at baseline, 2 months, and 6 months followed by a single dose of MenACWY-CRM 1 month later. Immunogenicity was assessed via serum bactericidal assay using human complement (hSBA) at 1 month postvaccination; solicited reactogenicity and adverse events were monitored. Fifty-four participants enrolled. Bactericidal immune responses were evident after each dose of 4CMenB, as assessed by hSBA geometric mean titers and percentages of subjects with hSBA titers of ≥4 against the test strains or a 4-fold rise in titer over baseline. At 1 month postvaccination, most MenACWY-CRM recipients had hSBA titers of ≥8 against serogroups A, C, W-135, and Y. Few participants discontinued due to an adverse event or vaccine reaction. Rates of solicited reactions were lower after MenACWY-CRM than after 4CMenB administration. Sequential administration of 4CMenB and MenACWY-CRM provided robust evidence of an immune response against serogroups A, B, C, W-135, and Y in laboratory workers routinely exposed to meningococcal isolates.
