目的对牛源性疫苗导致变异克雅氏病(vCJD)的风险进行评估,以便制定有效的预防控制措施。方法收集1994年以来国内外有关牛源性疫苗导致变异克雅氏病的流行病学、病原学、疫苗生产等方面的资料。结果目前两种不同的牛源性疫苗导致变异克雅氏病概率分别为1/400亿、1/4000万。结论目前牛源性疫苗导致变异克雅氏病的风险较小,但仍有必要对疫苗用牛源性物质加强控制、进一步改进疫苗生产技术。
Objectives To assess the risk of bovine-derived vaccine-induced Creutzfeldt-Jakob Disease (vCJD) in order to develop effective prevention and control measures. Methods Collecting the epidemiology, etiology and vaccine production of Creutzfeldt-Jakob disease that caused by bovine source vaccine at home and abroad since 1994. Results The prevalence of Creutzfeldt-Jakob disease caused by two different bovine source vaccines at present is 1/400 trillion and 1/40 million respectively. Conclusions At present, the risk of Creutzfeldt-Jakob disease caused by bovine vaccine is small, but it is still necessary to strengthen the control over the bovine source of vaccine and further improve the vaccine production technology.
