目的对武冈市实施麻疹疫苗强化免疫的结果进行分析,为降低麻疹发病率和实现在2012年消除麻疹行动计划提供对策依据。方法对武冈市2009年3—4月麻疹疫苗强化免疫期间的现场调查、评估报告和强化免疫后的麻疹监测系统和法定传染病报告系统的疫情资料进行综合分析。结果该次强化免疫共接种目标儿童139 557人,报告接种率为97.75%(139 557/142 774),快速评估调查接种率为98.67%(148/150)。共报告预防接种异常反应28例,发生率为3.71/10万。强化免疫后的2009年5—11月报告疑似病例4例,发病率为0.53/10万,比2008年同期病例明显减少。结论高质量的麻疹疫苗强化免疫能够迅速降低人群麻疹的发病率,今后应进一步提高常规免疫的接种质量,以形成有效的人群免疫屏障,阻断麻疹病毒的传播。
Objective To analyze the results of measles vaccine immunization in Wugang City and provide countermeasures for reducing the incidence of measles and implementing the measles elimination plan in 2012. Methods The epidemiological data of the measles surveillance system and the legal notifiable infectious disease reporting system during March to April 2009 during the 2009-2010 measles vaccine immunization in Wugang City were comprehensively analyzed. As a result, 139 557 children were enrolled in this intensive immunization. The reported vaccination rate was 97.75% (139 557/142 774) and the rate of quick assessment was 98.67% (148/150). A total of 28 cases of abnormal response to vaccination were reported, the incidence was 3.71 / 100000. Four cases of suspected cases were reported in May-November 2009 after intensive immunization, with a prevalence of 0.53 / 100000, which was significantly lower than the same period of 2008. Conclusions High-quality measles vaccine can rapidly reduce the incidence of measles in the population. In the future, we should further improve the vaccination quality of routine immunization so as to form an effective population immune barrier and prevent the spread of measles virus.
