  • Publication number: 20070148190
    Abstract: The present invention describes derivatized polysaccharide-protein conjugates, a composition comprising one or more of such derivatized polysaccharide-protein conjugates and methods of immunizing human patients with the same. The derivatized polysaccharide-protein conjugates are purified capsular polysaccharides from Nesseria meningitidis serogroups A, C, W-135, and/or Y, derivatized chemically activated and selectively attached to a carrier protein by means of a covalent chemical bond, forming polysaccharide-protein conjugates capable of eliciting long-lasting immunity to a variety of N. meningitidis strains.

  • Publication number: 20060170267
    Abstract: A new and improved all-terrain seat that is ideal for hunting, fishing, backpacking, camping, sports viewing, and the like. The all-terrain seat includes legs that are individually adjustable enabling the seat to be securely positioned on any surface, regardless of incline. The all-terrain seat is made from a lightweight material and is very portable as it may attach to a belt, easily fit inside a backpack, or be hand carried.

  • Publication number: 20050019337
    Abstract: The present invention describes methods of immunizing a patient with a combined vaccine that offers protection against meningococcal disease caused by the pathogenic bacteria Neisseria meningitidis serogroups A and C. The vaccine comprises at least two distinct polysaccharide-protein conjugates that are formulated as a single dose of vaccine. The purified capsular polysaccharides of Neisseria meningitidis serogroups A and C are chemically activated and selectively attached to a carrier protein by means of a covalent chemical bond, forming polysaccharide-protein conjugates capable of eliciting long-lasting immunity to a variety of N. meningitidis strains in infants.

  • Patent number: 5604108
    Abstract: The dosage response of humans to conjugate vaccines comprising a bacterial polysaccharide and a strongly-immunogenic carrier protein is determined in animals by coadministering to the animal unconjugated strongly-immunogenic carrier protein in an amount corresponding, on a weight-related basis, to that administered to the human.
