The short answer: there’s no money in Vitamin D, there is in vaccines. From Jonathan Cook at jonathan-cook.net:
It is probably not a good idea to write while in the grip of anger. But I am struggling to suppress my emotions about a wasted year, during which politicians and many doctors have ignored a growing body of evidence suggesting that Vitamin D can play a critically important role in the prevention and treatment of Covid-19.
It is time to speak out forcefully now that a new, large-scale Spanish study demonstrates not a just a correlation but a causal relationship between high-dose Vitamin D treatment of hospitalised Covid patients and significantly improved outcomes for their health.
The pre-print paper in the Lancet shows there was an 80 per cent reduction in admission to intensive care units among hospitalised patients who were treated with large doses of Vitamin D, and a 64 per cent reduction in death. The possibility of these being chance findings are infinitesimally small, note the researchers. And to boot, the study found no side-effects even when these mega-doses were given short term to the hospitalised patients.
