目的评价国家免疫规划疫苗上市后大规模应用的安全性、免疫效果和流行病学保护效果。方法采用主动监测和被动监测的方法观察疫苗上市后的安全性,采集适龄儿童甲肝疫苗免疫前后的血液标本进行抗体检测,采用1︰2病例对照研究进行甲肝、乙肝、结核和腮腺炎4种疫苗针对疾病的监测。结果 AEFI发生率居前三位的分别是麻疹风疹减毒活疫苗(18.81/10万)、乙脑减毒活疫苗(16.70/10万)和甲肝减毒活疫苗(12.71/10万);甲肝减毒活疫苗的免疫成功率为68%(34/50);共监测到1例乙肝病例,2例结核病例,126例流行性腮腺炎病例。结论中国疫苗安全性和甲肝疫苗的免疫效果较好,甲肝、乙肝疫苗的流行病学保护效果较好,卡介苗对肺结核的保护效果有限,含腮腺炎成分减毒活疫苗对腮腺炎的保护效果有待进一步研究。
