It's worth noting that vitamin D is not a secret magical panacea that is being hidden from us by Big Pharma because it doesn't make them $$$. It's also worth noting in regard to this myth that AZ are providing their vaccine at cost, with no profit motive.
Vitamin D may help against Covid to an extent, and is unlikely to harm unless you're mega-dosing. But it's not the single answer, or even the best answer. Vaccination is the way out of this. And until vaccination is at sufficient levels to provide herd immunity, then masks, social distancing etc are crucial.
Actually, vitamin D in large doses heals not only Covid, but most of the comorbidities, as well. THIS is the real reason the medical doesn't advertise it very much. V-D and the medical are mutually exclusive. Either no vitamin D in healing amounts, or no medical. Take your pick.
