【摘要】 １９９１年分层随机抽取１２个县（市）的４、８、１２岁组儿童１０４４名，按卫生部《计划免疫技术管理规程》对７种疫苗的免疫现状进行了监测。结果：抗体阳性率、ＧＭＴ分别为：麻疹８７．１６％±３．１４％、５．８３±０．４１（＜１：８者５６．９０％）；百日咳７８．１３％±９．１９％、２１８．１０±２３．３９（≥１：３２０者４１．６２％）；ＤＡＴ　７４．４７％±１１．０４％、０．０９８±０．０２５；ＴＡＴ　７５．８６％±１１．０９％、０．１３６±０．０３；脊灰（ＥＬＩＳＡ）：Ⅰ型８９．９９％、２２０．５１，Ⅱ型８３．３８％、２０１．２７，Ⅲ型８６．０９％、２７５．０８，三个型７９．４８％、２５５．９１（≥１：４００者２７．２３％）；乙脑（ＨＩ）６７．４７％±３．３４％、３９．４４±１．４８；ＯＴ试验阳性率２４．７３％。县市间、年龄组间差异显著（Ｐ＜０．０１）。４岁组调查接种率与免疫监测结果一致。麻疹抗体水平与发病呈完全负相关。基础免疫较好而加强免疫不够，甚至有免疫空白点、带。脊灰、麻疹、乙脑等的人群免疫屏障不够完善，有局部流行或爆发的可能。建议尽快进行５～１４岁儿童的麻苗普种和５岁以下儿童的脊灰疫苗普服，加强村医培训，?更多还原

【Abstract】 total of 1044 children selected in age groups of 4, 8 and 12 years old from 12 coun- ties(cities )with stratified random sampling method were monitored on the present situa- tion of immune levels according to the prog- ramme on immunization in 1991.The results showed that the positive rates and the geome- tric mean titers of antibodies to measles were 87.16%±3.14%,5.83±0.41(56.90%,<1:8),respectively;to pertussis were 78.13%±9.19%218,10±23.39(41.62%,≥1: 320); to DATwere 74.47%±11.04%,0.098±0.025; to TAT were75.86%±11.09%,0.136±0.03;to poliomyelitis(ELISA )were type Ⅰ 89.99Ⅰ%, 220.51. type Ⅱ83.38%,201.27, type Ⅲ 86.09%,275.08,3 types79.48%,255.91 ( 27.23%,≥1:400); to JapaneseB encephalitis(HI)were 67.47%±3.34%,39.44±1.48.The conversion of OT was 24.73%.Itshowed signifioant difference among thesecounties and among 3 age groups(P<0.01).In 4-year age group,the vaccinated rate andtbe result of immune surveilance were thesame.The ant ibody level and the incide nceof measles showed negative correlation.更多还原
