title: Schistosoma spp.: progress toward a defined vaccine.
abstract: During the last 2 decades, much was learned concerning the nature of acquired immunity in schistosomiasis, under experimental as well as field conditions. The knowledge is being applied now to design of a defined vaccine against this major parasitic disease. Several Schistosoma spp. antigens have been purified and shown to potentially protect in vivo. Determination of a method for presenting these antigens that will induce an optimal combination of cellular and humoral immune responses remains a critical step in vaccine development.
