About this study

Vitamin D is mainly obtained from the sun and follows a seasonal pattern, with Vitamin D levels peaking in summer and reaching a trough during winter. Vitamin D deficiency is associated with impaired immunity. However, knowledge of Vitamin D deficiency with in vivo immunity is limited. This observational study aims to investigate the relationship between Vitamin D status and the in vivo immunity.
