				        	 Leukocytoclastic vasculitis after the BNT162b2 vaccine and ChAdOx1 nCoV-19 Corona Virus vaccine [recombinant] has been observed. Herein, we report two cases of leukocytoclastic vasculitis that developed after the ChAdOx1-S [recombinant] vaccination. A 61-year-old and a 52-year-old woman presented with pruritic purpuric macules and papules on both lower legs. The patients had been vaccinated with the ChAdOx1-S [recombinant] vaccine. The histopathological analyses were consistent with a diagnosis of leukocytoclastic vasculitis. They were treated with oral prednisolone and improved within 1 month of treatment. We assume that the rash had arisen from the deposition of spike protein at the skin tissue induced by the viral vector of the COVID-19 vaccine or hyperimmune responses by excipients present in vaccine preparations. To our knowledge, our cases would be the first Korean cases of leukocytoclastic vasculitis after the ChAdOx1-S [recombinant] vaccination.
