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
血吸蟲病疫苗研究已有60多年的歷史,大致經歷了死疫苗、活疫苗(照射致弱尾蚴疫苗)和基因工程疫苗等研究階段,產生了一些who / tdr推薦認為很有希望的疫苗候選分子,如谷胱甘肽- s -轉移酶( gst ) 、副肌球蛋白( sm97 ) 、照射致弱疫苗抗原5 ( irv - 5 ) 、磷酸丙糖異構酶( tpi ) 、曼氏血吸蟲膜內在蛋白( sm23 )和脂肪酸結合蛋白( fabp , sm14 )等,但其對宿主的保護作用均不甚理想,未能穩定地達到40或以上的保護力水平,因此有必要繼續尋找新的疫苗抗原分子和/或疫苗佐劑,進一步提高其保護力。Study of deflagration - to - detonation transition of combustible gas
