New-onset bullous pemphigoid following the fifth dose of the COVID-19 vaccine Pfizer-BioNTech: A case report
Bibliographic record
Abstract
Bullous pemphigoid is recognized as the most prevalent autoimmune blistering skin disease. This report presents a case of a 54-year-old male in Canada who developed new-onset bullous pemphigoid 4 weeks after receiving his fifth COVID-19 vaccine booster (Pfizer-BioNTech). The patient initially presented with a generalized erythematous rash, which progressed despite treatment with topical and systemic corticosteroids. He later developed tense blisters and peripheral eosinophilia, with a skin biopsy confirming the diagnosis of bullous pemphigoid. Although bullous pemphigoid has previously been linked to various vaccinations, the underlying mechanisms remain uncertain. Notably, cases of bullous pemphigoid flare-ups have been reported in patients with existing bullous pemphigoid after receiving mRNA COVID-19 vaccines. This report underscores the importance of considering new-onset bullous pemphigoid in patients presenting with blistering skin conditions following COVID-19 vaccination.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
