为了解山西省免疫接种率现状 ,对近年计划免疫相关资料进行综合分析 ,结果显示 :1996～ 2 0 0 1年四种疫苗[卡介苗 (BCG)、口服脊髓灰质炎疫苗 (OPV)、百白破联合疫苗 (DPT)、麻疹疫苗 (MV) ]常规免疫估算接种率为5 8 79%～ 80 91% ,四种疫苗调查接种率为 81 5 0 %～ 97 74 % ;1993～ 1999年OPV强化免疫估算接种率为6 5 95 %～ 89 13%。说明常规免疫存在严重滑波现象。接种率监测的核心是掌握应种人数 ,免疫空白主要在 <1岁儿童 ,提示必须定期采取行之有效的查漏补种 ,才能消除免疫空白和提高免疫接种率水平 In order to understand the status quo of immunization coverage in Shanxi Province, a comprehensive analysis of the related information of planned immunization in recent years shows that: from 1996 to 2001, four kinds of vaccines [BCG, OPV (oral poliovirus vaccine, (DPT) and measles vaccine (MV) routine immunization coverage rate ranged from 58 79% to 80 91%, and the immunization rates of the four vaccines were from 81 5 0% to 97 74%. In the period from 1993 to 1999, OPV intensified immunization The estimated vaccination rates ranged from 65.95% to 89.13%. Routine immunization shows a serious slip phenomenon. At the core of inoculation rate monitoring is the number of respondents. The majority of immunization gaps are in children <1 year old, suggesting that effective leak detection and replanting must be regularly carried out in order to eliminate the immunization gap and raise the immunization coverage rate
