A new retrospective study has been published on PLoS ONE showing the significant role vitamin D plays in the body's defenses against COVID-19.
Of 1176 patients admitted, 253 had records of a 25(OH)D level prior to COVID-19 infection. A lower vitamin D status was more common in patients with the severe or critical disease (<20 ng/mL [87.4%]) than in individuals with mild or moderate disease (<20 ng/mL [34.3%] p < 0.001). Patients with vitamin D deficiency (<20 ng/mL) were 14 times more likely to have severe or critical disease than patients with 25(OH)D ≥40 ng/mL (odds ratio [OR], 14; 95% confidence interval [CI], 4 to 51; p < 0.001).
This study echoes the findings of 11 Randomized Controlled Trials which show on average a 51% improvement among patients receiving vitamin D supplementation as part of their COVID-19 treatment protocol.
It should also be noted that vitamin D levels have been negatively correlated with incidence of infectious respiratory disease since at least 2006
What makes this latest study noteworthy are the dates regarding its publication:
Received: June 27, 2021; Accepted: January 12, 2022; Published: February 3, 2022
This study sat in peer review limbo for six months. Was that because it contained findings that didn’t advance the “official” wisdom of “you must be vaccinated to ward off severe COVID-19”?
The world wonders….
