乙型肝炎疫苗(下简称乙肝疫苗)的诞生,保护了乙肝易感人群。目前,我国已具备在一部分人群中进行乙肝免疫预防的必要条件。鉴于我国乙肝病毒感染相当常见,需接受免疫保护人较多,乙肝疫苗的供应尚难满足要求,人群普种既不合理,也不实际,因此,有必要制定科学、合理的免疫预防方案。乙肝表面抗体(抗—HBs)是保护性抗体,可中和 HBV 的感染力。正常人接受HBsAg 的刺激后,使体内产生免疫应答,出现抗—HBs,获得了对 HBV 感染的免疫力。疫苗接种产生主动免疫的作用,主要适用于乙肝易感者暴露前的免疫保护。重点保护人群的确定:根据对产前检查孕妇的 HBsAg 的测定发现阳性率为11.0%。没有接受乙肝疫苗的 HBsAg 阳性母亲所生的
Hepatitis B vaccine (hereinafter referred to as hepatitis B vaccine) was born, to protect the hepatitis B susceptible population. At present, our country already has the necessary conditions for hepatitis B immunization in some people. Given that hepatitis B virus infection is quite common in our country, more immunoprotective recipients are needed and the supply of hepatitis B vaccine can hardly meet the requirements. It is neither reasonable nor practical for the population to popularize it. Therefore, it is necessary to formulate a scientific and reasonable immunoprophylaxis program. Hepatitis B surface antibodies (anti-HBs) are protective antibodies that neutralize the infectivity of HBV. After normal people receive the stimulation of HBsAg, make the body produce immune response, appear anti-HBs, get immunity to HBV infection. Vaccination have the role of active immunity, mainly for hepatitis B susceptible pre-exposure to immune protection. Focus on the protection of the population to determine: According to the prenatal examination of pregnant women HBsAg determination found that the positive rate was 11.0%. Born HBsAg-positive mothers who did not receive hepatitis B vaccine
