接种乙肝疫苗是控制HBV感染的有效措施。血源乙肝疫苗（下称血源苗）在我国已用十余年，对控制乙肝发病起到了重要作用。近年来，又用基因工程（重组酵母）乙肝疫苗（下称基因苗）替代血源苗，为观察两种疫苗全程免疫新生儿后抗～HBs产生情况，我们于1997年4月～1998年6月进行 Inoculation of hepatitis B vaccine is an effective measure to control HBV infection. Hepatic hepatitis B vaccine (hereinafter referred to as blood seedlings) has been used in our country for more than ten years and plays an important role in controlling the incidence of hepatitis B. In recent years, genetic engineering (recombinant yeast) Hepatitis B vaccine (hereinafter referred to as gene vaccine) to replace blood-borne seedlings, in order to observe the two vaccines throughout the newborn after anti-anti-HBs production, we in 1997 April ~ 1998 6 Month
