Treatment-Resistant Pemphigoid Following SARS-Cov-2 Vaccination

As the SARS-CoV-2 vaccinated population increases, there have been many reports of vaccine-induced cutaneous reactions but scarce information on vaccine-induced autoimmune bullous disease. Vaccinations have been associated with the unmasking or development of autoimmune bullous disease;however, there is little data on SARS-CoV-2, specifically. We report a rare case of new-onset pemphigoid in a 70-year-old male following the second dose of the mRNA-1273 vaccine. The patient’s disease has been refractory to treatment, thus the underlying pathophysiology in vaccine-induced pemphigoid is likely unique, and further investigation into this pathophysiology is warranted. © 2022 THE AUTHORS.
