Little is known about the risk of febrile seizures (FS) after vaccination with measles-containing vaccines (MCVs) in middle- and low-income countries. This self-controlled case series study aimed to evaluate the risk of FSs in Chinese children using data from the Ningbo Regional Health Information Platform. The observation period was 0-12 and 13-24 months of age for the MR and MMR vaccines, respectively. The relative incidences (RIs) within 0-6 days, 7-13 days, 14-27 days, and 28-42 days after vaccination with MCVs were estimated. The remaining observation period was the control period. The RIs within 0-6 days, 7-13 days, 14-27 days, and 28-42 days after MR vaccination were 1.11 [95% confidence interval (CI) 0.33 to 3.70], 0.80 (95% CI 0.23 to 2.86), 1.67 (95% CI 0.81 to 3.42), and 1.02 (95% CI 0.49 to 2.14), respectively. The corresponding RIs after MMR vaccination were 0.99 (95% CI 0.56 to 1.75), 1.17 (95% CI 0.68 to 2.01), 0.87 (95% CI 0.54 to 1.39), and 0.85 (95% CI 0.54 to 1.34), respectively. This study suggests that China's vaccination schedule for MCVs, as suggested by the World Health Organization (WHO) for countries with a high risk of measles mortality and ongoing transmission, does not increase the risk of FSs.
在中低收入国家,关于接种含麻疹疫苗(MCV)后发生热性惊厥(FS)的风险所知甚少。这项自我对照病例系列研究旨在利用宁波区域健康信息平台的数据评估中国儿童发生FS的风险。对于麻疹疫苗(MR)和麻腮风联合疫苗(MMR),观察期分别为0至12个月龄和13至24个月龄。估计了接种MCV后0至6天、7至13天、14至27天和28至42天内的相对发病率(RI)。其余观察期为对照期。接种MR疫苗后0至6天、7至13天、14至27天和28至42天内的RI分别为1.11[95%置信区间(CI)0.33至3.70]、0.80(95%CI 0.23至2.86)、1.67(95%CI 0.81至3.42)和1.02(95%CI 0.49至2.14)。接种MMR疫苗后的相应RI分别为0.99(95%CI 0.56至1.75)、1.17(95%CI 0.68至2.01)、0.87(95%CI 0.54至1.39)和0.85(95%CI 0.54至1.34)。本研究表明,世界卫生组织(WHO)针对麻疹死亡率高且仍有传播的国家建议的中国MCV疫苗接种计划不会增加FS的风险。
