内蒙古自治区4岁以下儿童麻疹疫苗强化免疫活动分析

目的内蒙古自治区在麻疹疫苗强化免疫前后的现场调查、评估,并对麻疹监测系统和传染病报告系统的疫情资料进行分析。方法所有8月龄～4岁儿童接种1剂麻疹疫苗,每剂次0.5mL。结果此次强化免疫接种儿童903 926人,调查和报告接种率均为97%以上;2010年麻疹发病人数明显减少,发病率仅2.83/10万,较2009年发病率6.03/10万下降53.07%;2010年麻疹监测系统数据显示,8月龄～4岁年龄组麻疹病例205例,与2009年相比麻疹发病率下降46.61%,57.29%的麻疹病例发生在8月龄～14岁,约85.80%病例无免疫史或免疫史不详,麻疹疫苗强化免疫疑似预防接种异常反应报告发生率为3.42/10万。结论高质量强化免疫是迅速控制麻疹流行、降低麻疹发病率的重要措施。为保持MV强化免疫取得的成果,必须提高常规免疫接种率,加强入托、入学查验预防接种证制度,使漏种儿童得到补种,同时在强化免疫后开展麻疹后续强化免疫。
