Severe aplastic anemia after BTN162b2 mRNA COVID-19 vaccination in a patient undergoing hemodialysis

Abstract

Although vaccination against coronavirus infection 2019 (COVID-19) has been found to be effective, reports of adverse reactions continue to appear. We report the development of severe aplastic anemia post BTN162b2 mRNA COVID-19 vaccination in patient undergoing dialysis. The pathogenesis and risk factors for post-vaccination aplastic anemia remain unclear. We must remain vigilant to aplastic anemia following COVID-19 vaccination. The risk of aplastic anemia should be identified, and management methods should be established.
