乙型脑炎在整个虫媒病毒感染中流行最广,由最北的苏联远东地区到最南的马来西亚、新加坡。现就疫苗免疫、病毒生态学的研究,以及乙脑的治疗情况介绍如下。 (一)疲苗的研究情况【灭活疫苗】目前为人群大规模免疫仍使用灭活疫苗,活疫苗免疫还在研究阶段。过去用的是鼠脑灭活疫苗,但因能引起过敏性脱鞘性脑脊髓炎的反应,现在国内外都在研究地鼠肾组织培养灭活疫苗。美国疫苗经初次免疫及加强免疫,免疫效果能维持 Japanese encephalitis is most prevalent throughout the entire arbovirus infection, from the far north to the far east of Malaysia, Singapore. Immunization is now on the vaccine, virus ecology, and treatment of JE described below. (A) the study of tired vaccine 【Inactivated vaccine】 At present, large-scale population still use inactivated vaccine, live vaccine immunization is still at the research stage. In the past is the mouse brain inactivated vaccine, but can cause allergic demyelinating encephalomyelitis response, both at home and abroad are studying the hamster kidney tissue inactivated vaccine. The United States vaccine by the initial immunization and strengthening of immunity, the immune effect can be maintained
