Researches of schistosomiasis vaccines have gone more than 60 years, approximately including from the stages of dead vaccine and live vaccine ( irradiated attenuated cercariae vaccine ) to gene engineered vaccine, etc. many different forms of vaccines have been tested in animal models, including gluthathione s - transferase, paramyosin, irv - 5, triose phosphate isomerase, sm23, fatty acid binding protein ; which were considered promising by who / tdr. but none of them steadily accomplished the pre - set target level of 40 % protection. in order to enhance the protective capacity further, it is essential to develop novel vaccine antigens and / or vaccine adjuvants
