Abstract: In one aspect, the invention relates to a composition including a first polypeptide having the sequence set forth in SEQ ID NO: 1 and a second polypeptide having the sequence set forth in SEQ ID NO: 2. In one embodiment, the composition includes about 120 μg/ml of a first polypeptide including the amino acid sequence set forth in SEQ ID NO: 1, 120 μg/ml of a second polypeptide including the amino acid sequence set forth in SEQ ID NO: 2, about 2.8 molar ratio polysorbate-80 to the first polypeptide, about 2.8 molar ratio polysorbate-80 to the second polypeptide, about 0.5 mg/ml aluminum, about 10 mM histidine, and about 150 mM sodium chloride. In one embodiment, a dose of the composition is about 0.5 ml in total volume. In one embodiment, two-doses of the composition induce a bactericidal titer against diverse heterologous subfamily A and subfamily B strains in a human.

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 also relates to immunogenic compositions comprising polysaccharide-protein conjugates, wherein the conjugates comprise a CP from GBS serotype IV and at least one additional serotype. 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. The resulting antibodies can be used to treat or prevent GBS infection via passive immunotherapy.
