摘　　要：[目的]了解乙脑疫苗强化免疫前后目标儿童抗体水平,为预防和控制乙脑提供科学依据。[方法]采用分层随机抽样方法,在免疫前和免疫后1个月采血,用反向被动凝集抑制试验检测血清抗体。[结果]免疫后目标儿童血清抗体阳性率由免疫前的34.71%上升至免疫后的99.16%,抗体几何平均滴度(GMT)由1︰3.40上升为1︰138.69;免疫前血清抗体阴性的儿童、免疫后抗体阳转率为98.78%。免疫后不同年龄、性别、民族、地区和免疫史的儿童血清抗体水平差异无统计学意义,免疫前抗体水平低者免疫后抗体阳转率高。[结论]强化免疫后目标儿童血清抗体水平明显升高,各年龄组均达到了96%以上的免疫成功率指标,具有较好的保护效果;免疫后血清抗体水平不受年龄、性别、民族、地区和免疫史等因素的影响。[ Objective] To understand the Japanese B Encephalitis （JBE） vaccine antibody level before and after strengthening immunization and provide the scientific basis for controlling JBE in the future. [ Methods] Used stratified randomization sampling method, the sera samples one month prior and post vaccination were collected and tested by RPHI assay for antibody response. [Results] The antibody positive rate of children raised from 34.71% to 99.16%, the GMT from 1 ： 3.4 to 1 ： 138.69; the antibody positive rates of the children whose JBE antibody were negative before immunization was 98.78% after inactivated JBE vaccination. The serum antibody level had no difference in the children＇s age, sex, race, region and immunity history. The lower the Children antibody＇ s level was before the immunity, the higher the children＇s antibody positive rate was after the immunity. [ Conclusion ] The children serum antibody level obviously goes up after strengthening immunization, the immunity success rate which all come to above 96% in each age group. The protection effect is better; the children antibody level is uninfluenced by age, sex, race, region and immunity history, etc. after the immunity.
