乙型肝炎病毒感染是引发肝炎、肝硬化和原发性肝癌的重要原因，接种乙肝疫苗是预防乙肝的最有效手段．目前我国已研制出并在人群中广泛应用基因工程乙肝疫苗，为了解重组酵母乙肝疫苗的免疫效果，我们于！997年对接种重组酵母乙肝疫苗者进行了观察，结果报道如下．l材料与方法
Hepatitis B virus infection is an important cause of hepatitis, cirrhosis and primary liver cancer. Hepatitis B vaccine is the most effective way to prevent hepatitis B infection. At present, China has developed and widely used in the population of genetically engineered hepatitis B vaccine, in order to understand the immune effect of recombinant yeast hepatitis B vaccine, we! 997 vaccination of recombinant yeast hepatitis B vaccine were observed, the results reported below. l Materials and methods
