Delayed-Onset Urticaria Following Vaccination for COVID-19

ABSTRACT

Background: As COVID-19 vaccines continue to be administered worldwide, there are an increasing number of studies documenting cutaneous reactions following vaccination. Systemic reactions, such as urticarial diseases, occur. Purpose(s) The main objective of this study was to investigate the association between urticaria and recent vaccination for COVID-19. Method(s) A retrospective chart review examining the association of urticaria and COVID vaccination was conducted. Result(s) We report 17 patients who developed an urticarial reaction following vaccination against COVID and one patient who developed an urticarial reaction following a COVID infection. The vast majority of the patients were women with a mean age of 42.8 years. Conclusion(s) Cutaneous manifestations often follow COVID vaccination and infection. It may be helpful to inquire about recent infections and vaccinations in patients presenting with urticarial diseases. Copyright © 2022 Journal of Dermatology and Dermatologic Surgery.
