Coronavirus disease 2019 (COVID-19) has become a pandemic, and vaccines remain the only effective tools available for ending it. However, their side effects, such as syncope, which mimics sudden cardiac death, are serious concerns. We herein report 6 cases of delayed vasovagal syncope and presyncope (VVR) caused by COVID-19 vaccination among 25,530 COVID-19 patients. The prevalence of delayed VVR due to COVID-19 vaccination was 0.026%. In addition, no delayed VVR was found among 17,386 patients who received the influenza vaccine. Delayed VVR is likely to be overlooked if medical staff are not aware of this symptom. This report provides significant information regarding effects of COVID-19 vaccination.
新型冠状病毒病 2019（COVID-19）已成为大流行疾病，疫苗仍然是终结它的唯一有效工具。然而，疫苗的副作用，如晕厥，类似于心源性猝死，令人严重关切。我们在此报告 25530 例 COVID-19 患者中的 6 例由 COVID-19 疫苗接种引起的延迟性血管迷走性晕厥和先兆晕厥（VVR）。COVID-19 疫苗接种引起的延迟性 VVR 的患病率为 0.026%。此外，在接受流感疫苗的 17386 例患者中未发现延迟性 VVR。如果医务人员没有意识到这种症状，那么延迟性 VVR 很可能被忽视。本报告提供了关于 COVID-19 疫苗接种效果的重要信息。
