  • Publication number: 20230321212
    Abstract: The invention relates to immunogenic polysaccharide-protein conjugates comprising a capsular polysaccharide (CP) from Streptococcus agalactiae, commonly referred to as group B streptococcus (GBS), and a carrier protein, wherein the CP is selected from the group consisting of serotypes Ia, Ib, II, III, IV, V, VI, VII, VIII, and IX, and wherein the CP has a sialic acid level of greater than about 60%. The invention also relates to methods of making the conjugates and immunogenic compositions comprising the conjugates. The invention further relates to methods for inducing an immune response in subjects against GBS and/or for reducing or preventing invasive GBS disease in subjects using the compositions disclosed herein.

  • Patent number: 10716839
    Abstract: Longer chain antigenic O-polysaccharide chains for use as a hapten in conjugate vaccines can be produced in a controlled manner using recombinant Gram-negative bacteria that overexpress native or heterologous genes of the wzz family, for example wzzB. Bacteria expressing a chosen wzz gene have modified O-polysaccharide chain lengths, allowing the bacteria to produce lipopolysaccharides having the longer O-polysaccharides. The LPS produced by the bacteria can be hydrolyzed to form core-O-polysaccharide molecules that can be conjugated to a carrier molecule, for example flagellin, to produce a vaccine. The invention also provides recombinant bacteria producing the longer chain O-polysaccharides, the polysaccharide molecules, themselves, conjugated vaccines comprising the O-polysaccharides, pharmaceutical compositions and kits.

  • Patent number: 6691319
    Abstract: A simulated necktie knot for use with a necktie to create a necktie knot without necessitating the hand-tying of a knot. The simulated necktie knot has a flexible funnel shaped cup, simulating a necktie knot, and a rigid funnel shaped core that fits within the cup. The core is used to fill the space within the cup not otherwise occupied by the necktie. A clip, positioned within the cup, holds the necktie in place within the cup. An adjustable collar strap may be used with the simulated necktie knot to attached the tie around the user's neck.
