麻疹的预防剂可分为两类;一为免疫物质类,又有自动免疫及被动免疫之分;一为类似抗病毒性质(或说似可降低麻疹病毒对人体的敏感性)的药剂,目前所知的如中药紫草根。麻疹的自动免疫自1940年拉凱(Rake)及莎菲(Shaffer)二氏以鸡胚移植所得之麻疹滤过性病毒传染于猿,而患轻型麻疹,其后虽以病人的传染性分泌物接种之,而猿猴也不再发病,从而证明有可能制造自动免疫制剂以来,国內外学者仍在继续研究中。迄今为止,目前尚无将麻疹病毒减弱到接种后不能发生麻疹,而
There are two types of prophylactic agents for measles; one is an immunological substance, and another is autoimmune and passive immunization; one is an agent of similar antiviral properties (or that may reduce measles virus sensitivity to the human body) Known as the traditional Chinese medicine comfrey root. Automatic Immunization of Measles The transmission of measles virus from chick embryos to rapes and Rhesus shakers from 1940 to the apes with light measles results in the subsequent transmission of infectious measles secretions Inoculation, and apes are no longer disease, which proves the possibility of manufacturing autoimmune preparations since, domestic and foreign scholars are still continuing to study. To date, no measles virus has been attenuated until measles can not be vaccinated
