The search term was "hepatitis B vaccine".Study selection Original studies conducted in China and critical reviews authored by principal investigators in the field of hepatology in China were selected.Results Chinese investigators started to develop hepatitis B vaccine in late 1970s. The first home-made plasma-derived vaccine became available in 1986, which has been completely replaced by the domestically produced recombinant (yeast or Chinese hamster ovary cell) vaccine since 2001. China health authority recommended vaccinating all infants in 1992. From then on, China has put tremendous efforts in implementation of mass vaccination. The overall coverage of hepatitis B vaccine in infants has increased steadily and reached more than 95.0% in urban and 83.0%-97.0% in rural areas. The chronic HBV carrier rate in children 〈10 years of age decreased from 10.0% before the mass vaccination to 1.0%-2.0% in 2006, and that in general population decreased from 10.0% to 7.2%; overall, the nationwide mass hepatitis B vaccination has reduced more than 30 million of chronic HBV infections and HBV related severe sequlae.Conclusion The Chinese successful experience in control of hepatitis B by mass vaccination offers an example for any unindustrialized country whoever is committed to control this disease.展开更多

目的评价彝良县地震灾区18月龄~14岁儿童甲型肝炎疫苗(Hepatitis A Vaccine,Hep A)群体性接种情况和流行病学效果。方法采用回顾性描述的方法对彝良县4个灾区乡镇的Hep A接种率、甲肝发病情况进行分析。结果4个乡镇共接种Hep A 50 58...目的评价彝良县地震灾区18月龄~14岁儿童甲型肝炎疫苗(Hepatitis A Vaccine,Hep A)群体性接种情况和流行病学效果。方法采用回顾性描述的方法对彝良县4个灾区乡镇的Hep A接种率、甲肝发病情况进行分析。结果4个乡镇共接种Hep A 50 584名儿童,报告接种率(98.36%)高于调查接种率(86.11%)和快速评估接种率(74.77%)。接种乡镇与对照乡镇比较,甲肝疫情下降趋势明显,发病率从2010年313.03/10万下降至2013年39.35/10万。接种Hep A后无14岁以下甲肝病例报告。接种中仅发生2例轻微疑似预防接种异常反应。结论本次地震灾后Hep A群体性接种经过科学、规范的组织,达到预防甲肝流行的效果,为今后类似灾后免疫规划应对积累了经验。展开更多
