“Effect of calcifediol treatment and best available therapy versus best available therapy on intensive care unit admission and mortality among patients hospitalized for COVID-19: A pilot randomized clinical study”
calcifediol = the active form of vitamin D
www.ncbi.nlm.nih.gov/pmc/articles/PMC7456194/
First randomised double blind controlled study on vitamin D as a treatment for covid (not just prophylaxis).
76 patients admitted to Córdoba hospital. 50 were randomly allocated to the treatment group, they were given the best standard care and treatment PLUS calcifediol (vit D). The other group of 26 were the control and just given the best standard care/treatment (no vit D)
Of the 50, only one patient was admitted to intensive care (2%). None died, no complications. Of the 26 in the non-calcifediol group, 13 were admitted to intensive care (50%), two of whom sadly died.

We found a significant crude relationship between average vitamin D levels and the number COVID-19 cases, and particularly COVID-19 mortality rates, per head of population across the 20 European countries.
Vitamin D has been shown to protect against acute respiratory infections, and older adults, the group most deficient in vitamin D, are also the ones most seriously affected by COVID-19.
A previous study found that 75% of people in institutions, such as hospitals and care homes, were severely deficient in vitamin D.

^These results demonstrate an inverse relationship between circulating 25(OH)D levels and SARS-CoV-2 positivity. For the entire population those who had a circulating level of 25(OH)D
