Usually those sorts of studies involve one big infusion when the person has already become sick.
Same thing with HCQ studies that “don’t work” - the treatment is applied late instead of early as an intervention to prevent things from getting worse.
Additionally, it takes a while for vitamin D to build up. You can’t raise levels in one shot like that.
The most recent study I saw simply measured the relationships between Vit D levels and outcomes from the disease. No added Vit D. Higher levels of Vit D were associated with significantly improved outcomes. (Association only; not causation.)

There is a possibility it is a surrogate marker, but Christ it’s such an easy thing to distribute with minimal side effects.
