医院就诊接种在免疫接种中的补充作用

The Supplementary Effect of Consulting Vaccination in EPI

采用ＰＰＳ法对甘肃省两县４２０名儿童一周岁以内的医院就诊率进行调查，分析结果表明：儿童在县、乡医院总就诊率为３０．２４％，平均就诊次数为２．１４次；就诊接种对不同疫苗基础免疫的补充作用系数分别是ＢＣＧ０．３０２４，ＭＶ０．０６４３，ＴＯＰＶ－３０．０９５３，ＤＰＴ－３０．０９２９，就诊接种对不同疫苗提供一次免疫的补充作用系数分别是ＢＣＧ０．３０２４，ＭＶ０．０６４３，ＴＯＰＶ－３０．２６４３，ＤＰＴ－３０．２３８１，并对不同针次。

This study was carried out in 420 of chil- dren aged 12-24 months in two counties of Gansu Province,China.The result showed that general consulting rate was 30.24% in county or township hospital.The average consulting time was 2.14.A formula was designed K= R×C(1-V) for detecting the effect of con- sulting vaccination in EPI.The maximum sup- plementary coefficients of initial immuniza- tion of outpatient children for the vaccines were as follows:BCG 0.3024,TOPV-3 0.0953,DPT- 3 0.0929,MV 0.0643.And once immunization were BCG 0.3024,TOPV 0.2643,DPT 0.2381,MV 0.0643.The study also explores the supple- mentary effect of consulting vaccination in dif- ferent vaccination times and immunization coverages.
