This case series from 3 academic hospital-based pediatric and adolescent gynecology services outlines the temporal association between vulvar ulcers in female adolescents and COVID-19 vaccination. We identified 8 cases and describe each patient's presentation, differential diagnosis, diagnostic workup, complications, treatment modalities, and overall course of illness. All cases seek to illustrate the clinical experiences of patients and providers interfacing with vulvar aphthous ulcers and contribute to the emerging literature exploring the novel association between vulvar aphthous ulcers and COVID-19 vaccination. To date, this is the largest described case series of this association in the literature.
