[Immunologic behavior of meningococcal vaccines]

Abstract

Meningococcal disease continues to be a great health problem on all continents and the meningococcal vaccines have been proposed for their prevention and epidemic control. The polysaccharide A and C vaccines are relatively efficacious with distinct immunological behavior with regard to the different age groups, however, up to the present no highly efficacious vaccine for meningococcal B disease exists. The meningococcal B capsular polysaccharide is not immunogenic due to the structural mimicry of mammalian tissues and efforts to produce carrier proteins have been proposed in order to obtain an immunogenic vaccine for all age groups that would if possible, protect against all the meningococci. This review of the literature presents the study of the development of the immunological behavior of all the meningococcal vaccines undergoing development and reports on the efforts to obtain a safe and efficacious product for the control of meningococcal disease.
