Brief Summary
Vitamin D plays a pivotal but still not well understood role in the immune response to coronavirus disease (COVID-19) infection and vaccination. Many studies also showed a high negative correlation between the severity of inflammatory disease and serum 25-hydroxyvitamin D levels. Patients with acne vulgaris often had deteriorated skin condition after COVID-19 vaccination. Therefore, this study aimed to investigate the relationship of COVID-19 vaccination with serum 25-hydroxyvitamin D level and severity of acne vulgaris.
