目的:分析海南州疑似预防接种异常反应(AEFI)监测资料,了解AEFI系统的运转情况。方法:用描述性流行病学分析对海南州2015年的疑似预防接种异常反应监测数据进行分析和评价。结果:2015年AEFI监测系统共报告AEFI病例35例,报告发生率为7.28/10万。全州各县均有AEFI病例报告。AEFI病例县级覆盖率为100%。报告病例最多的县是共和县,共报告16例,其次各县报告情况是,同德县3例、贵德县2例、贵南县7例、兴海7例。全年除3、5、9月份外均有病例发生,4月份和12月份病例报告最多,为6例,其次为10月份和11月份,为5例。35例AEFI病例中,1岁以下年龄组共27例(其中0岁17例、1岁10例),2岁组~7岁组8例。全州无群体性AEFI发生。结论:海南州AEFI监测系统运转良好,及时报告率与及时调查率较高,但需进一步改良疫苗生产工艺,以降低疫苗导致的不良反应发生率。

Methods: Descriptive epidemiological analysis was conducted to analyze and evaluate the 2015 surveillance data of suspected immunization in Hainan Province.
