Adverse reactions, including the onset of diabetes, after coronavirus disease 2019 (COVID-19) vaccination have been reported. Herein, we report a case of a man who developed anti-glutamic acid decarboxylase (GAD) antibody-positive fulminant type 1 diabetes 15 weeks after COVID-19 vaccination, atypical of the previously reported anti-GAD antibody-negative cases.
Keywords: COVID‐19 vaccination; anti‐glutamic acid decarboxylase (GAD) antibody; diabetic ketoacidosis; fulminant type 1 diabetes.
