新生儿乙肝疫苗免疫后,随着免疫年限延长,乙肝病毒表面抗体(抗-HBs)阳性率和几何平均滴度(GMT)均逐年下降,但大量研究证实乙肝疫苗安全、有效,对于阻断乙肝病毒(HBV)的传播起到了重要作用。目前,人们十分关注的问题是乙肝疫苗在人群中的免疫持久性,及加强免疫针次和剂量的必要性,为了评价不同针次和剂量乙肝疫苗加强免疫效果,我们于2002年对大兴区435名3-12岁儿童开展现场问卷调查和血清学研究,结果报告如下。
After immunization with newborn hepatitis B vaccine, with the extension of immunization years, the positive rate of hepatitis B virus surface antibody (anti-HBs) and geometric mean titer (GMT) decreased year by year, but a large number of studies have shown that hepatitis B vaccine is safe and effective for blocking hepatitis B The spread of the virus (HBV) has played an important role. At present, people are very concerned about the problem of hepatitis B vaccine in the population of the immune persistence, and to strengthen the needles and doses of immunization need to assess the effect of different doses and doses of hepatitis B vaccine to enhance the immune effect, we Daxing District in 2002 435 Name 3-12-year-old children on-site surveys and serological studies, the results are reported below.
