乙型肝炎疫苗(HBVAX)为一种从乙型肝炎病霉(Dane颗粒)的表面抗原提出的无感染性的灭活亚单位病毒疫苗。乙型肝炎疫苗(乙肝疫苗)为无菌的肌肉注射液,每1mc疫苗含20ug,乙型肝炎(下称乙肝)表面抗原,以氢氧化铝为佐剂,硫柳汞作防腐剂。疫苗不分亚型。临床研究指出,接种乙肝疫苗后,大多数3月龄以上的儿童或成人可产生对乙肝病毒的中和抗体,这种中和抗体对接触病毒后有保护效果。实验观察在某些感染可能性很大的人群接种后可减少90%以上的感染率。疫苗可保护人群不患急性乙肝,无症状感染和慢性抗原血症。注射2～3针
Hepatitis B vaccine (HBVAX) is a non-infectious inactivated subunit virus vaccine raised against the surface antigen of Hepatitis B virus (Dane particles). Hepatitis B vaccine (Hepatitis B vaccine) is a sterile intramuscular injection containing 20 μg of vaccine per 1 mc of hepatitis B surface antigen (hereinafter referred to as hepatitis B), adjuvanted with aluminum hydroxide and thimerosal as a preservative. Vaccines regardless of subtype. Clinical studies indicate that most children over 3 months of age or adults develop a neutralizing antibody against hepatitis B virus after vaccination with hepatitis B vaccine. This neutralizing antibody has a protective effect against virus exposure. Experimental observation reduces the infection rate by more than 90% after inoculation in some people who have a high possibility of infection. Vaccines protect the population from acute hepatitis B, asymptomatic infections and chronic antigenemia. Injection 2 to 3 needles
