乙型肝炎(HB)疫苗接种提供的保护作用时间有限,当抗体滴度低于10IU/L而接种者仍处于感染HB病毒(HBV)的危险状态时,需要进行加强接种.但加强接种的时间难以确定.作者检测了健康医务人员接种HB疫苗后的抗体下降速率,以估计抗体半衰期与接种后抗体水平之间的关系.
Vaccination with Hepatitis B (HB) provides limited protection and requires intensive vaccination at antibody titers of less than 10 IU / L while the vaccinee is still in a dangerous state of being infected with Hepatitis B virus (HBV) Difficult to determine.The authors tested the rate of antibody decline following HB vaccination by health care workers to assess the relationship between antibody half-life and antibody levels after vaccination.
