目的对施甸县两轮麻疹疫苗(MV)强化免疫情况及效果进行分析,为该县尽早消除麻疹提供科学依据。方法利用施甸县2008年、2010年麻疹疫苗强化免疫报告、调查接种率,2010-2014年麻疹Ig G抗体水平调查及法定麻疹报告系统资料进行统计学描述。结果施甸县强化免疫报告、调查接种率均在97%以上;两轮强化免疫后,麻疹Ig G抗体水平明显提高,5年人群抗体阳性率均在90%以上且平均率达93.83%;同时,麻疹发病率由2007、2008年的平均发病率3.76/10万下降至2009年的0.30/10万,两轮强化免疫后6年平均发病率0.1/10万,发病以0~岁组及20~岁组为主。结论两轮强化免疫后,施甸县麻疹流行强度、范围得到有效控制,抗体水平得到明显提高,为该县尽早消除麻疹奠定了坚实基础。
Objective To analyze the intensified immunity and its effect of two rounds of measles vaccine in Shidian County and provide a scientific basis for the county to eliminate measles as soon as possible. Methods The epidemic situation of measles vaccine in Shidian County in 2008 and 2010, the vaccination coverage, the IgG antibody level of measles in 2010-2014 and the reporting system of measles were analyzed. Results In the Shidian County, the immunization coverage rate was above 97%. After two rounds of immunization, the level of IgG antibody in measles increased significantly. The positive rate of antibody in five years population was over 90% and the average rate was 93.83%. Meanwhile, , The incidence of measles decreased from 3.76 / 100000 in 2007 and 2008 to 0.30 / 100000 in 2009. The average incidence of measles in the six years after two rounds of immunization was 0.1 / 100000. ~ Group-based. Conclusion After two rounds of intensive immunization, the intensity and range of measles epidemic in Shidian County have been effectively controlled, and the antibody level has been significantly improved, laying a solid foundation for the county to eliminate measles as soon as possible.
