The invention relates to the development of chimeric OspA molecules for use in a new Lyme vaccine. More specifically, the chimeric OspA molecules comprise the proximal portion from one OspA serotype, together with the distal portion from another OspA serotype, while retaining antigenic properties of both of the parent polypeptides. The chimeric OspA molecules are delivered alone or in combination to provide protection against a variety of Borrelia genospecies. The invention also provides methods for administering the chimeric OspA molecules to a subject in the prevention and treatment of Lyme disease or borreliosis.

1. A composition comprising a combination of polypeptides, wherein the combination comprises (i) a polypeptide comprising the amino acid sequence with at least 90 percent sequence identity to the amino acid sequence set forth in SEQ ID NO:2, (ii) a polypeptide comprising the amino acid sequence with
1. A composition comprising a combination of polypeptides, wherein the combination comprises (i) a polypeptide comprising the amino acid sequence with at least 90 percent sequence identity to the amino acid sequence set forth in SEQ ID NO:2, (ii) a polypeptide comprising the amino acid sequence with at least 90 percent sequence identity to the amino acid sequence set forth in SEQ ID NO:4, and (iii) a polypeptide comprising the amino acid sequence with at least 90 percent sequence identity to the amino acid sequence set forth in SEQ ID NO: 6, said composition formulated in a unit dose of about 10 μg to about 100 μg, and a pharmaceutically acceptable carrier. 2. The composition of claim 1, wherein the combination comprises (i) a polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 2, (ii) a polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 4, and (iii) a polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 6. 3. The composition of claim 1 formulated in a unit dose of about 10 μg. 4. The composition of claim 1 formulated in a unit dose of about 30 μg. 5. The composition of claim 1 formulated in a unit dose of about 60 μg. 6. The composition of claim 1 formulated in a unit dose of about 90 μg. 7. The composition according to claim 1, wherein the composition further comprises an adjuvant. 8. The composition according to claim 7, wherein the adjuvant is aluminum hydroxide. 9. The composition according to claim 2, wherein the combination of polypeptides comprises an equal amount of each polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 2, 4, or 6. 10. The composition according to claim 1, wherein the composition is formulated in a unit dose effective to increase Borrelia antibody production in a subject to a geometric mean titer (GMT) level of about 1,000 to 10,000 at about 60 days after initial dosing. 11. The composition according to claim 1, wherein the composition is formulated in a unit dose effective to increase Borrelia antibody production in a subject to a geometric mean titer (GMT) level of about 2,000 to 30,000 at about 90 days after initial dosing. 12. The composition according to claim 1, wherein the composition is formulated in a unit dose effective to increase Borrelia antibody production in a subject to a geometric mean titer (GMT) level of about 15,000 to 50,000 after booster administration. 13. The composition according to claim 1, wherein the unit dose is about 10 μg to about 90 μg. 14. The composition according to claim 13, wherein the unit dose is about 20 μg, about 30 μg, about 40 μg, about 50 μg, about 60 μg, about 70 μg, or about 80 μg. 15. A method of inducing a protective immune response against Borrelia infection or Lyme disease in a subject comprising administering to the subject an immunologically effective amount of the composition of claim 1. 16. The method of claim 15, wherein the immunologically effective amount of the composition is administered in a single unit dose. 17. The method of claim 15, wherein the immunologically effective amount of the composition is administered in multiple unit doses. 18. The method of claim 17, wherein the multiple unit doses are administered at about monthly intervals. 19. The method of claim 17, wherein a booster of the composition is further administered at about 6 to about 18 months after the initial unit dose. 20. The method of claim 17, wherein a booster of the composition is further administered at about 9 to about 12 months after the initial unit dose. 21. The method of claim 17, wherein the composition is administered at about Day 1, at about Day 29, and at about Day 57. 22. The method of claim 21, wherein a booster of the composition is further administered at about 9 months to about 12 months after the first unit dose. 23. The method according to claim 15, wherein the unit dose is about 10 μg to about 90 μg. 24. The method according to claim 23, wherein the unit dose is about 30 μg or about 60 μg.
