Suggested mechanism of autoimmune‐mediated alopecia areata following COVID‐19 vaccine, , : The existence of molecular mimicry between the vaccine‐induced proteins of SARS‐CoV‐2 and human components might give rise to pathological autoantibodies. Adjuvants may have a role in the production of these autoantibodies. (Created with BioRender.com)
