文摘目的 评价不同细胞基质制备的肠道病毒71型(EV71)灭活疫苗上市后常规免疫安全性。 方法 EV71灭活疫苗疑似预防接种异常反应(AEFI)数据来源于中国免疫规划信息管理系统,为2017年接种EV71 灭活疫苗后江苏省报告的监测数据;受种儿童人口学信息和接种剂次数来源于江苏省预防接种信息管理系统。 结果 2017年江苏省共接种EV71灭活疫苗316 889剂,报告AEFI 208例,报告发生率为65.64/10万剂(95% CI :56.72/10万剂~74.56/10万剂),其中一般反应55.54/10万剂(95% CI :47.34/10万剂~63.74/10万剂),异常反应 7.89/10万剂(95% CI :4.80/10万剂~10.98/10万剂);不同细胞基质的疫苗AEFI发生率(χ 2 =35.61, P <0.01)和一般反应发生率(χ 2 =34.09, P <0.01)差异有统计学意义,异常反应发生率差异无统计学意义(χ 2 =1.88, P =0.17),均未见严重异常反应,208例AEFI均未住院且均痊愈。EV71灭活疫苗(Vero细胞)首剂接种一般反应发生率高于第二剂(χ 2 =6.94, P <0.01),不同季度接种EV71灭活疫苗(人二倍体细胞)一般反应发生率差异有统计学意义(χ 2 =18.86, P <0.01)。 结论 不同细胞基质的EV71灭活疫苗在常规免疫接种中AEFI发生率均不高,有良好的安全性;一般反应以发热为主,异常反应以过敏性-荨麻疹、过敏性皮疹和过敏性斑丘疹等过敏性反应为主。
