COVID-19 vaccine-associated vitiligo: A cross-sectional study in a tertiary referral center and systematic review.

As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus continues to infect patients globally, vaccination remains one of the primary methods to combat this prolonged pandemic. However, there are growing reports of coronavirus disease 2019 (COVID-19) vaccines possibly triggering autoimmunity, irrespective of the vaccine's design. This phenomenon has been observed in patients with vitiligo, with a rising number of cases reporting new-onset or worsening vitiligo following COVID-19 vaccinations. In this study, the authors present the most extensive case series of COVID-19 vaccine-associated vitiligo to date, along with a systematic review of the literature. The aim is to assist physicians in the clinical evaluation of patients with vitiligo with regard to future vaccinations.
