目的分析2010-2012年9月石嘴山市疑似预防接种异常反应(adverse events following immunization,AEFI)监测系统报告的预防接种后发生的疑似预防接种异常反应事件,评价疫苗的安全性,提高接种服务质量,从而增强公众对预防接种的信心。方法通过收集疑似预防接种异常反应监测系统2010-2012年9月AEFI个案数据进行分析。结果石嘴山市2010-2012年9月共报告33例AEFI病例,通过分析,AEFI发生率居前4位的疫苗分别为:麻疹疫苗、麻风疫苗、白破疫苗、乙脑疫苗。2012年报告病例数较多,主要发生在≤8月龄儿童。结论 AEFI发生取决于多种因素,选用免疫效果好且安全性高的预防性生物制品,提高接种人员的技术水平,严格按照预防接种工作规范操作,掌握各种疫苗的禁忌症,做好疫苗接种前询问、告知及预检筛查,可以减少AEFI的发生。
Objective To analyze the suspected abnormal vaccination events after vaccination reported by the AEFI surveillance system in Shizuishan City from September 2010 to September 2012 to evaluate the safety of vaccines and improve the quality of vaccination services. Thus increasing public confidence in vaccination. Methods The data collected from the AEFI case of suspected antivirus reaction surveillance system from September 2010 to September 2012 were collected for analysis. Results A total of 33 AEFI cases were reported from 2010 to 2012 in Shizuishan City. According to the analysis, the top 4 AEFI vaccines were measles vaccine, leprosy vaccine, diphtheria vaccine and Japanese encephalitis vaccine. There were a large number of reported cases in 2012, mainly occurring in children ≤ 8 months of age. Conclusions The occurrence of AEFI depends on many factors. The preventive biological products with good immunological effect and high safety are selected to improve the technical level of vaccinators. In strict accordance with the standardized operation of vaccination work, the contraindications of various vaccines should be mastered and vaccinated Pre-inquiry, notification and pre-screening screening, can reduce the occurrence of AEFI.
