目的了解内蒙古自治区2011年常规免疫接种情况,对常规免疫接种率监测结果进行评价。方法通过差值法和比值法对监测结果进行比较分析。结果内蒙古全区卡介苗(BCG)、百白破疫苗(DPT)、乙肝疫苗(HepB)、脊髓灰质炎疫苗(PV)、麻类疫苗(MCV)和乙脑疫苗(JE)六苗常规免疫报告接种率均高于99%,估算接种率均小于95%。全区D值评价为不可信,R值评价为可信。结论内蒙古常规免疫接种率报告真实性、准确性有待提高。 Objective To understand the routine immunization in Inner Mongolia Autonomous Region in 2011 and evaluate the results of routine immunization surveillance. Methods By comparing the difference and the ratio method to monitor the results. Results The routine immunization reports of BCG, DPT, HepB, PV, MCV and JE in Inner Mongolia were inoculated. Rates were higher than 99%, estimated vaccination rates were less than 95%. Region D value is evaluated as not credible, R value is evaluated as credible. Conclusion The accuracy of routine immunization coverage in Inner Mongolia needs to be improved.
