Acute Severe Ulcerative Colitis After mRNA Coronavirus Disease 2019 Vaccination: Can mRNA Vaccines Unmask Inflammatory Bowel Diseases?

ABSTRACT BNT162b2 is a messenger RNA vaccine for the prevention of the novel coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 infection. The widespread use of this vaccination has brought along several adverse events. We present a patient with newly diagnosed ulcerative colitis after BNT162b2 vaccine.
