Interactions of conjugate vaccines and co-administered vaccines

Conjugate and Polysaccharide Vaccines Conjugate and Polysaccharide Vaccines, Plenary Review Meningococcal polysaccharide-protein conjugate vaccines

Glycoprotein conjugate vaccines.

The polysaccharide capsule which surrounds bacterial species like Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis, Salmonella typhi, is a potent virulence factor. It protects the bacterium from phagocytosis, but capsule specific antibodies plus complement binding to the capsule opsonise the organism for phagocytosis and elimination. Purified capsules elicit T-independen...

Pneumococcal conjugate vaccines

To assess whether certain serogroups of Streptococcus pneumoniae are preferentially associated with specific disease manifestations, we analyzed all recent pneumococcal disease studies and assessed the relative frequency of isolation of each serogroup by clinical site (as a proxy for different disease states). In all age groups, serogroups 1 and 14 were more often isolated from blood, and serog...

Meningococcal group C conjugate vaccines

In November 1999 the Department of Health introduced a national vaccination programme using newly licensed meningococcal serogroup C conjugate vaccines (MenC). In the largest national mass vaccination campaign ever undertaken in the UK, all people under the age of 18 years are being oVered vaccination: three doses for infants as part of the primary vaccination schedule at 2, 3, and 4 months of ...

Bacterial polysaccharide±protein conjugate vaccines*

The age-related and T-cell independent properties of polysaccharides limit their use as vaccines. These limitations are overcome by covalently binding polysaccharides to proteins to form conjugates. Widespread use of Haemophilus in ̄uenzae type b (Hib) conjugates has virtually eliminated systemic infection caused by this pathogen, notably meningitis, in individuals of all ages. The principles de...
