Immunogenic compositions for the prevention and treatment of meningococcal disease
The present invention relates to Neisseria ORF2086 proteins, crossreactive immunogenic proteins which can be isolated from nesserial strains or prepared recombinantly, including immunogenic portions thereof, biological equivalents thereof, antibodies that immunospecifically bind to the foregoing and nucleic acid sequences encoding each of the foregoing, as well as the use of same in immunogenic compositions that are effective against infection by Neisseria meningitidis serogroup B.
1. A composition comprising a first isolated protein having at least 98% sequence identity to SEQ ID NO: 58, and a second isolated protein having the amino acid sequence set forth in SEQ ID NO: 250.
2. The composition of claim 1 , wherein the first isolated protein and the second isolated protein are recombinant.
3. The composition of claim 1 , wherein the first isolated protein and the second isolated protein are lipidated.
4. The composition of claim 1 , wherein the first isolated protein and the second isolated protein are isolated from a Neisseria bacterium.
5. The composition of claim 4 , wherein the bacterium is Neisseria meningitidis.
6. The composition of claim 1 , further comprising a polysaccharide.
7. The composition of claim 1 , further comprising an adjuvant.
8. The composition of claim 7 , wherein the adjuvant is aluminum phosphate.
9. The composition of claim 1 , further comprising a buffer.
