１９９６年４月，河北省在接受计划免疫第三个８５％目标审评时，除对儿童进行接种率调查外，还用ＥＬＩＳＡ方法检测麻疹抗体。结果表明：８７０名儿童麻疹抗体阳性率为９１０％，几何平均滴度（ＧＭＴ）为１：５２４８１。各地儿童麻疹抗体阳性率和ＧＭＴ的差异有显著的统计学意义，而不同地貌、城乡和性别之间均无显著差异。提示全省该年龄组儿童麻疹抗体阳性率处于较高水平，但ＧＭＴ偏低。结合接种率和疫情资料分析，近年河北省不会发生麻疹流行，但由于各种原因造成的易感者积累，发生局部的暴发或病例数上升是可能的 In April 1996, while accepting the third 85% target review of planned immunization in Hebei Province, measles antibody was detected by ELISA in addition to the survey of children’s vaccination rate. The results showed that the positive rate of measles antibody in 870 children was 910%, and the geometric mean titer (GMT) was 1: 52481. There were significant differences in the positive rates of measles antibody and GMT among children, but no significant difference was found between different topography, urban and rural areas and gender. Prompted the province’s children in this age group measles antibody positive rate at a high level, but GMT low. Combining with the vaccination rate and epidemic situation data analysis, there will be no measles epidemic in Hebei Province in recent years. However, due to the accumulation of susceptible persons due to various reasons, it is possible to have a local outbreak or an increase in the number of cases
