Abstract
The ongoing COVID-19 pandemic required a firm and prompt effort in the development of an effective vaccine. Reports of adverse reactions are increasing. Lichen planus, as well as its oral variant, is a condition that has previously been reported to be associated with vaccines. This is one of the first reports of oral lichen planus (OLP) arising after any COVID-19 vaccine. Here the authors present 2 cases of OLP that occurred after BNT162b2 mRNA COVID-19 vaccination (Comirnaty, Pfizer, New York, NY, USA; BioNTech, Mainz, Germany).
