美国食品药物管理局于1981年11月正式批准生产乙型肝炎血源性疫苗,并且在1982年6月开始出售,这是美国第一次直接用人血制成的第一代疫苗.由于各种原因,如HBsAg阳性血浆来源困难,价钱昂贵等,使血源性疫苗的生产受到限制.因此,近年来正在通过各种途径致力于寻找纯度更大,来源容易而又价廉物美的疫苗,并已取得一定的进展.下面就近年来有关乙型肝炎疫苗的研究及应用情况进行介绍.
The U.S. Food and Drug Administration formally approved the production of a Hepatitis B blood-borne vaccine in November 1981 and was sold in June 1982. It was the first U.S.-made first-generation vaccine made directly from human blood. The reason is that the production of blood-borne vaccines is limited because of the difficulties in the source of the HBsAg-positive plasma, the high cost, etc. Therefore, in recent years, various approaches are being taken to find vaccines of greater purity, easier source, more cheap and cheap Some progress has been made.The following is a brief introduction about the research and application of hepatitis B vaccine in recent years.
