Alopecia areata after COVID-19 vaccination

The coronavirus disease 2019 (COVID-19) vaccines are authorized for use in numerous countries worldwide. Several cutaneous findings are reported after severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) vaccination. Here, we report the case of a patient with a rapid onset of alopecia areata immediately after receiving the second dose of the COVID-19 vaccine. Alopecia areata is a common autoimmune disease leading to non-scarring hair loss. Among the many cutaneous adverse effects reported after the anti-SARS-COV2 vaccination, no episodes of alopecia areata have been described to date. In this paper, we report the first case of alopecia areata after COVID-19 vaccination described in the literature with a revision of cases of alopecia areata reported after other types of vaccination. Although the signifi-cance of these skin reactions is not yet known, further studies will certainly clarify whether the development of alopecia areata or other forms of immune-mediated reactions could represent a positive prognostic factor regarding immune protection from SARS-CoV-2.
