Monovalent Carbohydrate-based Vaccine Development

Monovalent Carbohydrate-based Vaccine Development

Monovalent vaccines are designed to immunize against a single antigen or a single microorganism, and in some cases, monovalent vaccines may be preferable to produce a strong immune response rapidly. CD BioGlyco has established an advanced and specialized platform to provide scientific assistance to clients in the field of monovalent carbohydrate-based vaccine development.

Background of Monovalent Carbohydrate-based Vaccine

In 1929, Avery and Goebel proved that the immunogenicity of capsular polysaccharides could be enhanced by coupling to carrier proteins. Unfortunately, this discovery was not taken seriously until Robbins and Schneerson synthesized a glycoconjugate vaccine using HibCPS (poly ribosylribitol phosphate) and DT, which became the first conjugate vaccine licensed for use in children under 2 years of age in the USA in 1987 because of its higher immunogenicity and efficacy in clinical trials. The success of the Hib glycoconjugate vaccines spurred the development of monovalent meningococcal glycoconjugate vaccines using DT or TT as the carrier protein, providing longer immune responses and higher immunity to serogroup C in children under 2 years of age.

Among the 13 meningococcal serogroups, serogroups A, B, C, X, Y and W135, are the most pathogenic strains of all meningococcal infections. To date, Neisseria meningitides vaccines have been developed using natural polysaccharides, glycoconjugates, and outer membrane vesicles (OMP). Currently, in addition to three licensed quadrivalent meningococcal conjugate vaccines against serotypes A, C, Y and W135, three licensed monovalent serogroup C conjugate vaccines and one licensed monovalent serogroup A vaccine (MenAfriVac) apply to all age groups.
