PROBLEM TO BE SOLVED: To provide cross-protective vaccines or compositions effective to various MnB isolated strains.SOLUTION: In one aspect, the invention relates to a composition comprising 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.SELECTED DRAWING: Figure 1 |
