[目的]对我县1993～2000年8次15轮强化免疫效果进行评价。[方法]将县防疫站脊髓灰质炎(简称脊灰)计划免疫资料,县脊灰监测专报资料及省站脊灰实验室检验资料进行总结分析。[结果]全县4岁以下儿童累计服苗403093人次,服苗率达99.65％,有效地提高了人群免疫水平。出生队列分析,每次强化免疫均有一定比例的常规漏服儿童得到补服,漏服率随年龄增长而减少,同一年龄组漏服率随强化免疫次数的增加而下降,1岁以上零剂次在第四次强化免疫之后逐步消失,显示免疫及时性有所提高。[结论]据脊灰监测结果,连续18a无脊灰病例,AFP病例监测未检出脊灰野病毒,提示强化免疫效果好。
[Objective] To evaluate the effects of 15 rounds of intensive immunization for 8 times in our county from 1993 to 2000. [Method] The poliomyelitis (polio) immunization data of the county epidemic prevention station, poliovirus monitoring data of the county and polio laboratory test data of the province were summarized and analyzed. [Results] The total number of children under 4 years old in the county totaled 403,093, taking 99.65% of the vaccine for children, effectively raising the population immunity level. Birth cohort analysis, each time there is a certain proportion of the routine immunization of children who have missed the regular supplements, the rate of missed service decreases with age. The rate of missed service in the same age group decreases with the increase in the number of intensive immunizations. Over 1 year old and zero Times in the fourth after the gradual disappearance of immunization, immunity and timeliness has improved. [Conclusion] According to poliovirus monitoring results, there was no polio cases for 18 consecutive years. No poliovirus was detected in AFP cases, which indicated that the effect of intensive immunization was good.
