Abstract
CoronoVac is a non-viable vaccine for severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). Nowadays, there has been vaccination program for at-risk groups and older adults in Turkey. We here present 72-year-old male psoriasis patient who developed generalized pustular psoriasis flare after administration of CoronoVac. The COVID-PCR test was negative and investigations for flare etiology were all normal. He was first (to the best of our knowledge) psoriasis patient who developed an erythrodermic flare after the first dose of CoronaVac vaccine.
