Using the tetravalent meningococcal polysaccharide-protein conjugate vaccine in the prevention of meningococcal disease.
Invasive meningococcal disease occurs worldwide causing an estimated 50,000-135,000 deaths each year in addition to significant sequelae. In developed countries the disease is usually sporadic but outbreaks and epidemics, usually due to serogroups B and C, have occurred. In the US, an increasing number of cases are due to serogroup Y. In developing nations, epidemics due to serogroups A and more recently W-135, are common. The tetravalent meningococcal conjugate vaccine to serogroups A, C, Y, and W-135 (MCV4) has been demonstrated to be highly immunogenic and promote immune memory. This article will describe the rationale for the vaccine and its potential role to significantly decrease mortality and morbidity of meningococcal disease in those areas and populations at greatest risk from these serogroups.
