dc.description.abstract Understanding the specificity of antibody response to Neisseria meningitidis serogroup B (Men B) is a key requirement for the development of an effective vaccine. This study was designed to investigate the antigen specificity of murine IgG1 and IgG2b antibodies induced by different primary immunization schedules and the booster dose with the Cuban Men B vaccine. Immunoblotting analyses were performed using outer membrane vesicles (OMV) from the vaccine strain (B:4,7:P1.19,15). IgG subclasses binding to PorA, PorB and RmpM were determined by digital scanning of the immunoreactive bands. Bactericidal antibody response after vaccination was also evaluated. The results indicated that IgG2b anti-PorA was the main antibody response induced by two doses of the vaccine. A primary series of three doses was found important for increasing IgG2b as well as IgG1 to PorB and RmpM. The fourth dose favoured the recognition of RmpM as detected by the increase of specific IgG1 and IgG2b. IgG subclasses anti-PorA did not change significantly if animals received two, three or four doses of the vaccine during the primary immunization or after the booster dose for all vaccine groups. The booster response to PorB and RmpM of groups BC2 and BC3 showed a significant increase in IgG2b levels compared with the primary response. However, the recall and the primary response of group BC4 were similar, suggesting a saturated dose– effect response after four doses of vaccine. The same was seen for bactericidal antibody response when human complement source was used in the assay. pt_BR
