Coronavirus disease 2019 (COVID-19) has emerged as a global pandemic until today, but treatment options remain limited. COVID-19 vaccination is expected to decrease the number of patients with COVID-19 worldwide. In Japan, two types of mRNA COVID-19 vaccine, BNT162b2 (Pfizer/BioNTech) and mRNA-1273 (Moderna), have been approved and administered. However, their side effects remain poorly elucidated. This paper presents two cases of immune thrombocytopenia (ITP) after BNT162b2 mRNA COVID-19 vaccination. Whether or not ITP is triggered by the vaccination or not is difficult to identify. Further investigation with a large number of cases is warranted to clarify the side effects of BNT162b2 mRNA COVID-19 vaccination.
截至今日,2019冠状病毒病(COVID-19)已演变成一场全球大流行,但治疗选择仍然有限。预计COVID-19疫苗接种将减少全球COVID-19患者的数量。在日本,两种mRNA COVID-19疫苗,BNT162b2(辉瑞/生物新技术公司)和mRNA-1273(莫德纳公司)已获批准并投入使用。然而,它们的副作用仍未得到充分阐明。本文介绍了两例接种BNT162b2 mRNA COVID-19疫苗后发生免疫性血小板减少症(ITP)的病例。很难确定ITP是否由疫苗接种引发。有必要通过大量病例进行进一步调查,以阐明BNT162b2 mRNA COVID-19疫苗接种的副作用。
