河北省2010—2018年含麻成分疫苗补充免疫疑似预防接种异常反应监测分析

Surveillance of adverse events following supplementary immunization with measles-containing vaccines in Hebei Province,2010-2018

目的了解河北省2010—2018年含麻成分疫苗(measles-containing vaccine,MCV)补充免疫活动中疑似预防接种异常反应(adverse events following immunization,AEFI)特征,为及时妥善处置补充免疫活动中发生的不良反应提供科学依据。方法通过全国AEFI信息管理系统和各市专项上报的MCV补充免疫接种数据,对河北省2010—2018年MCV补充免疫活动中AEFI监测数据进行描述流行病学分析。结果河北省2010—2018年MCV补充免疫共报告AEFI个案2590例,总报告发生率为64.40/10万剂;男性略多于女性,年龄主要集中在0~6岁的儿童。不良反应报告发生率为63.10/10万剂,其中,一般反应为54.03/10万剂、异常反应为9.08/10万剂。62.19%的异常反应临床诊断为过敏反应导致的皮疹。严重异常反应报告发生率为3.18/10万剂。不良反应主要发生在接种后1 d内。结论河北省2010—2018年MCV补充免疫的AEFI病例以一般反应为主。异常反应以过敏导致的皮疹类为主,严重异常反应报告发生率未见明显升高。

Objective To understand the features of adverse events following immunization(AEFI)after supplementary immunization activity of measles-containing vaccines(MCV)in Hebei Province during 2010-2018,and to provide a scientific basis for promptly and properly disposing the adverse reactions in supplementary immunization activity.Methods Based on the data from the National AEFI Information Management System and MCV supplementary immunization data specially reported by each city,a descriptive epidemiological analysis was performed on the surveillance data of AEFI after supplementary immunization activity of MCV in Hebei Province from 2010 to 2018.Results A total of 2,590 cases of AEFI after MCV supplementary immunization were reported in Hebei Province from 2010 to 2018,with a totally reported incidence rate of 64.40 per 100,000 doses.The male cases were slightly more than the female cases.Most of the AEFI cases were children aged 0-6 years.The reported incidence rate of adverse reactions was 63.10 per 100,000 doses,with a reported incidence rate of 54.03/100,000 doses for common vaccine reactions and a reported incidence rate of 9.08/100,000 doses for rare vaccine reactions.60.19%of the rare vaccine reactions were clinically diagnosed as rashes caused by anaphylaxis.The reported incidence rate of severe vaccine reactions was 3.18/100,000 doses.The adverse reactions mainly occurred within one day after vaccination.Conclusion Most of the AEFI cases after supplementary immunization with MCV in Hebei Province during 2010-2018 were common vaccine reactions.The majority of rare vaccine reactions were clinically diagnosed as rashes caused by anaphylaxis.There was no significant increase in the reported incidence rate of severe vaccine reactions.
