目的研究麻疹减毒活疫苗强化免疫效果,探讨预防控制措施,为消除麻疹提供依据。方法用描述性流行病学方法,分析2009年麻疹疫苗强化免疫活动开展情况,收集2009与2010年麻疹发病资料并对强化免疫接种效果进行分析。结果 2009年麻疹疫苗强化免疫活动适龄儿童接种报告接种率98.66%,调查接种率99.21%,各年龄组儿童接种率均在97%以上;2009年与2010年麻疹报告发病率分别为8.45/10万和0.53/10万,麻疹疫苗强化免疫前后麻疹发病率下降了93.73%;发病人群麻疹IgM抗体阳性率2009年80.00%,2010年28.57%。结论2009年麻疹强化免疫活动效果显著,应进一步研究麻疹免疫策略,以适应消除麻疹的需要。
Objective To study the effect of live attenuated measles vaccine to enhance immunity and to explore preventive and control measures to provide the evidence for eliminating measles. Methods Descriptive epidemiological methods were used to analyze the progress of 2009 measles vaccine intensified immunization activities. The incidence of measles in 2009 and 2010 was collected and the effect of intensive immunization was analyzed. Results The immunization coverage rate of measles cases in 2009 was 98.66%, the survey inoculation rate was 99.21%, and the vaccination rate of children in all age groups was over 97%. The incidence rates of measles in 2009 and 2010 were 8.45 / And 0.53 / 10 million respectively. The incidence of measles decreased by 93.73% before and after the measles vaccine immunization. The positive rate of measles IgM antibody in the infected population was 80.00% in 2009 and 28.57% in 2010. Conclusion 2009 measles measles immunization activities are significant, should further study measles immunization strategies to meet the need to eliminate measles.
