Protection against cutaneous leishmaniasis induced by recombinant antigens in murine and nonhuman primate models of the human disease.

Leishmaniasis affects approximately 2 million people each year throughout the world. This high incidence is due in part to the lack of an efficacious vaccine. We present evidence that the recombinant leishmanial antigens LmSTI1 and TSA, which we identified and characterized previously, induce excellent protection in both murine and nonhuman primate (rhesus monkey) models of human cutaneous leishmaniasis.
