Bullous pemphigoid (BP) is an acquired auto-immune blistering disease, which is uncommon during childhood. Infantile BP usually has a good prognosis with rare recurrence and the suspected triggers are vaccines or viruses. We report the case of a three-month-old infant girl who presented with BP a week after a SARS-CoV-2 infection and three weeks after the first doses of polio, tetanus, diphtheria, pertussis, Haemophilus influenzae type-b, hepatitis, and pneumococcus vaccinations. Both triggers (infection and vaccination) could be implicated as a slight recurrence was observed after the second doses of vaccines. Rapid clinical resolution was obtained with topical corticosteroids.
