More particularly it relates to the use of polysaccharides containing the tetrasaccharide repeat unit: (?3)-?-DGalpNAc-(1?2)-?-D-PerpNAc-(1?3)-?-L-Fucp-(1?4)-?-D-Glcp-(1?), and conjugates thereof, to induce serum antibodies having bactericidal (killing) activity against hemolytic-uremic syndrome (HUS) causing E. coli, in particular E. coli O157. The conjugates, and compositions thereof, are useful as vaccines to induce serum antibodies which have bactericidal or bacteriostatic activity against E. coli, in particular E. coli O157, and are useful to prevent and/or treat illnesses caused by E. coli O157.

  • Publication number: 20090214586
    Abstract: Vaccines have been studied that comprise (a) D-T-Pw-HepB-Hib antigens and (b) one or more meningococcal conjugate antigens. A number of improvements and variations of these vaccines have been discovered. The vaccines can be prepared extemporaneously at the time of use by mixing together two components: (a) a first component comprising D, T, wP and HBsAg antigens; and (b) a second component comprising a Hib conjugate and one or more meningococcal conjugates.

  • Publication number: 20090155299
    Abstract: The present invention relates to conjugates of oligosaccharides of formula 1, wherein R is a linker to a carrier protein and optionally comprises up to three further saccharides, 5 and which are useful for vaccination, methods of synthesis of such conjugates, antibodies against this antigen, hybridoma producing monoclonal antibodies against this antigen, assays using these antibodies for the detection of B. anthracis spores and kits comprising these antibodies, and a vaccine for the prevention of B. anthracis infection comprising the conjugates of oligosaccharides of formula 1. Monoclonal antibodies 10 according to the invention selectively bind to B. anthracis, but not to related bacteria such as B. subtilis, B. cereus and other bacteria of this group such as B. thuringiensis.
