Immunogenic formulation of OspC antigen vaccines for the prevention and treatment of lyme disease and recombinant methods for the preparation of such antigens
A novel approach to Borrelia vaccine formulation taking into account serological, genotypic and epidemiological information by which OspC proteins from different strains of B. burgdorferi are grouped together. OspC antigens are chosen in order to constitute a representative sample of such groupings, so that the resulting vaccine provides the greatest cross-protectivity with the fewest number of antigens.
1. A vaccine effective to immunize a susceptible mammal against Lyme borreliosis infection comprising
a) an immunogenic amount of an OspC antigen consisting essentially of SEQ ID NO. 2; an OspC antigen consisting essentially of SEQ ID No. 4; an OspC antigen consisting essentially of SEQ ID No. 8 and an OspC antigen consisting essentially of SEQ ID No. 12, wherein said amount is in the range of 1 to 100 ug per antigen
b) an antigen selected from the group consisting of an OspA antigen from B. burgdorteri strain B31, an OspA antigen from B. burgdorferi strain Orth and an OspA antigen from B. burgdorferi H4, and an OspA antigen from B. burgodorferi strain KL11, and
c) a physiologically acceptable excipient.
2. The vaccine of claim 1 , wherein said mammal is a human.
3. The vaccine of claim 1 , wherein said amount is in the range of 10 to 50μ per antigen per dose.
4. The vaccine of claim 1 , wherein said OspC antigen is a recombinant polypeptide produced in transformed microbial cells.
5. A method of immunizing a mammal against Lyme borreliosis comprising administering to said mammal the vaccine of claim 1 .
6. The method of claim 5 , wherein said mammal is a human.
7. The method of claim 5 , wherein said vaccine is administered in an amount in the range of 10 to 50 micrograms per antigen per dose.
