Our study aimed to evaluate the safety of CoronaVac, an inactivated vaccine made by Sinovac, in children aged 7-14. We conducted a parent-administered online survey to monitor adverse reactions after vaccinating children in Taizhou, China, from February 15, 2021, to January 19, 2022. 767 parents completed the survey after receiving a questionnaire via WeChat. Overall, 15.3 % (117/767) of children experienced adverse effects after the first dose, and 12.2 % (88/724) after the second. Muscle pain was the most common adverse reaction post-first dose (10.0 %), while localized pain or itching at the injection site was most common after the second dose (7.6 %). In conclusion, the vaccine has a low incidence of side effects. The mild to moderate, transient, and common nature of these effects further boosts parents' confidence in vaccinating their children.
我们的研究旨在评估科兴新冠病毒灭活疫苗（克尔来福）在 7-14 岁儿童中的安全性。我们在中国泰州开展了一项家长在线调查，以监测自 2021 年 2 月 15 日至 2022 年 1 月 19 日为儿童接种疫苗后的不良反应。767 名家长在通过微信收到问卷后完成了调查。总体而言，15.3%（117/767）的儿童在接种第一针后出现了不良反应，12.2%（88/724）在接种第二针后出现了不良反应。肌肉疼痛是接种第一针后最常见的不良反应（10.0%），而接种第二针后最常见的不良反应是注射部位局部疼痛或瘙痒（7.6%）。总之，该疫苗的副作用发生率较低。这些不良反应的轻度至中度、短暂和常见性质进一步增强了家长对为儿童接种疫苗的信心。
