Large dose of calcifediol or vitamin D up to 15 days before COVID hospitalization reduced death rates (1.5X, 1.3X) – Dec 2021

COVID-19 is a major worldwide health problem because of acute respiratory distress syndrome, and mortality. Several lines of evidence have suggested a relationship between the vitamin D endocrine system and severity of COVID-19. We present a survival study on a retrospective cohort of 15,968 patients, comprising all COVID-19 patients hospitalized in Andalusia between January and November 2020. Based on a central registry of electronic health records (the Andalusian Population Health Database, BPS), prescription of vitamin D or its metabolites within 15-30 days before hospitalization were recorded. The effect of prescription of vitamin D (metabolites) for other indication previous to the hospitalization was studied with respect to patient survival. Kaplan-Meier survival curves and hazard ratios support an association between prescription of these metabolites and patient survival. Such association was stronger for

  • calcifediol (Hazard Ratio, HR = 0.67, with 95% confidence interval, CI, of [0.50-0.91]) than for
  • cholecalciferol (HR = 0.75, with 95% CI of [0.61-0.91]),

when prescribed 15 days prior hospitalization.
Although the relation is maintained, there is a general decrease of this effect when a longer period of 30 days prior hospitalization is considered (calcifediol HR = 0.73, with 95% CI [0.57-0.95] and cholecalciferol HR = 0.88, with 95% CI [0.75, 1.03]), suggesting that association was stronger when the prescription was closer to the hospitalization.

Observation by VitaminDWiki

Apparently this region in Spain prescribed either 256 mcg of calcifediol or 25,000 IU of vitamin D
These appear to be once a month doses
It appears that only those with <20 of vitainm D are given these prescroptions
Many other studies have found both to fight COVID - via prevention or tratment
Suspect that these are not new prescrptions, but rather just the day a new pill was given (have sent a question to one of the authors)

Amazon (US) now sells calcifediol

~2 months supply of calcifediol costs $20
Vs 2 months supply of Vitamin D (50,000 IU) costs ~ 20 cents (100 X lower cost)
