In these cases, the doctors aren’t giving the patient a clean bill of health across all parameters. They’re just confirming that the immediately life threatening issues are no longer an imminent danger to the patient. It’s entirely likely that the patient suffered more insidious, long-term health consequences that aren’t immediately obvious.
It should also go without saying that the excessive vitamin D doses didn’t do her any favors. The “more is better” approach to vitamins in the alternative medicine community really needs to stop.
It's thought the old recommended dose is to low for some people or some situations. Which is why they really want to push it up as much as possible for all because it will save lives.
Hence these studies. I'm doing 1000UI daily given current data and covid-19.
