Abstract

Serogroup C meningococcal conjugate vaccines, first launched in the UK in 1999, have been used successfully in Australia, Canada and several other European countries. Combination conjugate vaccines, containing more than one meningococcal polysaccharide, have been developed to broaden protection against the disease. A tetravalent meningococcal A, C, Y and W-135 conjugate vaccine was licensed for use in 11–55 year old adolescents and adults in the US in January 2005, and subsequently also in 2–11 year old children in Canada in May 2006. This article discusses the different glycoconjugate meningococcal vaccines which have been developed and the potential for their use to control disease caused by serogroups A, C, Y and W-135 of Neisseria meningitidis.

  • Search strategy: Data for this review were identified by searching PubMed and Medline databases up to and including October 2006. Only English language papers were reviewed. The following were the search terms used: “conjugate”, “meningococcal vaccine”, “serogroup A”, “serogroup C”, “serogroup Y”, “serogroup W-135”, “bivalent”, “quadrivalent” and “tetravalent”. Other sources were references identified in retrieved articles and online publications by health authorities of different countries.

  • Author’s contribution statement: DP performed the search and prepared the draft for this review which was subsequently revised by AJP.
