Coronavirus disease 2019 (COVID-19) vaccine administration started in February 2021 in Japan. As of December 2021, approximately 75% of the population aged ≥12 years had received two doses of vaccine. We conducted a study to investigate vasovagal reactions (VVR) after COVID-19 vaccination using data on adverse events following immunization. The crude reporting rate of VVR (cases/1,000,000 doses) after vaccination was 9.6 in all age groups combined, and was more frequent in the younger age groups: 28.6 and 37.2 in individuals aged 10-19 years and 20-29 years, respectively. In individuals aged 10-29 years, the rate was similar in males and females (33.0 and 34.2, respectively, p = 0.53); but was higher after dose 1 than after dose 2 (57.4 and 8.8, respectively, p < 0.001). Based on these results, caution needs to be exercised when vaccinating adolescents and young adults, especially with dose 1 of COVID-19 vaccines.
2019 年冠状病毒病（COVID-19）疫苗于 2021 年 2 月在日本开始接种。截至 2021 年 12 月，约有 75%的 12 岁以上人群接种了两剂疫苗。我们利用疫苗接种后不良事件的数据进行了一项研究，以调查 COVID-19 疫苗接种后的血管迷走神经反应（VVR）。所有年龄组接种后 VVR（每 100 万剂病例数）的粗报告率为 9.6，年龄较小的组更为常见：10-19 岁和 20-29 岁的个体分别为 28.6 和 37.2。在 10-29 岁的个体中，男性和女性的发生率相似（分别为 33.0 和 34.2，p=0.53）；但第 1 剂后高于第 2 剂（分别为 57.4 和 8.8，p<0.001）。基于这些结果，在为青少年和年轻人接种疫苗时需要谨慎，尤其是接种 COVID-19 疫苗的第 1 剂时更应如此。
