【目的】 了解西安市未央区流动人口聚集地区儿童免疫规划 7 种疫苗[卡介苗(BCG)、脊髓灰质炎疫苗(OPV)、百白破疫苗(DPT)、含麻疹成分疫苗(MCV)、乙肝疫苗(HepB)、乙脑疫苗(JEV)、流脑疫苗(MPV)]预防接种现状。 【方法】 采用单纯随机抽样法随机抽取居住 ≥3 个月的1~2岁流动儿童和常住儿童各758 名,进行免疫规划7种疫苗的接种率调查。 【结果】 调查儿童建证率 100.0% ,建卡率99.9 %。7 种疫苗BCG、 OPV、 DTP、 MCV、 HepB 、JEV、 MPV的基础免疫接种率分别为 99.5 %、 99.4 %、97.8 %、 92.5 %、 98.4 % 、90.9%、93.1%,7苗合格免疫覆盖率为90.9%。但流动儿童的 7 种疫苗合格免疫覆盖率(86.8%)显著低于常住儿童(95.3%),差异有高度统计学意义 (P<0.01);DTP加强免疫和MCV复种接种率分别为94.0%和94.4%。与常住儿童相比 ,流动儿童的7种疫苗基础免疫接种率除MCV、JEV基础免疫接种率为 89.7 %、86.8%外,其它疫苗的基础免疫接种率均高于90 %;除BCG和HepB首针及时接种率外其它各项指标流动儿童与常住儿童之间差异均有高度统计学意义(P<0.01) 。另外,7种疫苗针次中以超期、未种接种较多。 【结论】 在流动人口聚集地区 ,做好常住儿童免疫接种同时 ,还要加强流动儿童的预防接种工作。

【Objective】 To investigate the vaccination status of seven kinds of national immunization program vaccines(BCG,OPV,DPT,MCV,HepB,JEV and MPV) for migrant children in Weiyang district of Xi'an city. 【Method】 758 migrant children and 758 local children of 1~2 years old who lived in the street committees more than or equal to 3 months were sampled by simple random sampling method. 【Results】 100.0% of the total children had immunization cards and 99.9% of them had immunization certificates.The basic vaccination rates of BCG,OPV,DPT,MCV,HepB,JEV and MPV vaccines were respectively 99.5%,99.4%,97.8%,92.5%,98.4%,90.9%,and 93.1%.The immunization coverage of seven vaccines was 90.9%.But the immunization coverage of migrant children (86.8%) was significantly lower than that of local children (95.3%).DTP booster shot rate was 94.0% and MCV revaccination rate was 94.4%.Except MCV(89.7%) and JEV(86.8%),the basic vaccination rates of other five vaccines among migrant children were all higher than 90.0%.Except the BCG vaccination rate and the first hepatitis B vaccine inoculation rate,there were significant differences of other indexes between migrant children and local children.In addition,extending time and unvaccinated were the main problems of injection times. 【Conclusion】 In the floating population gathering areas,apart from completing the work of routine immune-inoculation for local children,more attention should be paid to strengthen the immune program vaccines inoculation work for migrant children.
