Vaccines against human parasitic diseases: an overview.
There are no vaccines currently available to control the major human parasitic diseases, although there is evidence of acquired immunity and resistance to reinfection in most of the parasitic infections. The present manuscript concentrates on the vaccines for parasitic diseases that are in the most advanced stages of development: malaria, leishmaniasis and schistosomiasis. Vaccines for malaria and leishmaniasis have been taken to clinical trials while vaccines for schistosomiasis are being considered for Phase I (assessment of safety and immune responsiveness in volunteers). We have attempted to give a factual account of the present status of knowledge of vaccines against human parasitic diseases, emphasizing both the successes and setbacks. We do not intend to cover the enormous literature in the field but have concentrated on the most promising antigenic preparations. Finally, some new approaches for the development of vaccines are discussed including nucleic acid vaccines and the use of cytokines as adjuvants.
