Although the role of vitamin D in reducing risk of SARS-CoV-2 infection and COVID-19 severity and death was kept from the mass media due to Big Pharma using the Disinformation Playbook against vitamin D,1 research on this topic continued in the peer-reviewed journal literature. Early in 2022 an observational study from Barcelona was published reporting that inhabitants who received vitamin D supplements and raised serum 25-hydroxyvitamin D [25(OH)D] concentrations above 30 ng/mL compared to those who did not have vitamin D prescriptions and had had serum 25(OH)D <20 ng/mL had lower rates of SARS-CoV-2 infection and severe COVID-19. For mortality, the hazard ratio = 0.66 [CI 95% 0.46-0.93].2 Similar results were found for calcifediol [25(OH)D] prescriptions.
Where are your Clinical Trials?
It has proven to be difficult, if not impossible, to proceed to full-scale randomized controlled trials (RCTs) for most of the natural methods that cannot be patented or otherwise monopolized.
