Conditions
Brief summary
The objective of the study is to evaluate the clinical efficacy and safety of vitamin D supplementation in hospitalized patients with COVID-19.
Detailed description
Phase IV, interventional, randomised, double blind, placebo-controlled and parallel study to evaluate the clinical efficacy and safety of vitamin D supplementation in hospitalized patients with COVID-19. Patients will participate in the study for a maximum of 9 weeks, which includes an up to 6-week treatment period and a maximum of 3-week follow-up period. A total of 100 (50 in each group) patients will be randomized in the study and will either receive the test treatment or the placebo treatment.

Exclusion criteria
