This has been a big problem. Some people labeled science on vitamin D & covid19 as misinformation, lumping vitamin D in with things that have little to no evidence even when the vitamin D evidence was mounting rapidly. Part of the point of this open letter is to show that many serious people agree that vitamin D should be used in the pandemic. The inappropriate suppression of this message is now the mis-information. This should be clear from reading the letter and its very few references carefully.

The problem IMHO is the attempt to regulate speech on the topic (or any topic really). It just illustrates the problems with it.

I'm a little concerned about the appeal to authority element to this all...

> A few months ago people laughed at the suggestion. It was "dangerous" to "deceive" people about Vit D and Covid.

Who? Doctors or people on the internet?

> Wasn't Twitter suppressing this too?

I don't know. Were they? By "too" do you mean the unidentified people above?

> How do they punish themselves for misinformation?

How do they punish themselves for insinuations of possibly suppressing something?

> Now it comes out. I wonder how many other things will come to light.

Such as what?

Last automn, I asked a medical doctor about Vitamin D and CoVid19 and he told me that he gets a lot of emails about news in medicine, and that he deletes everything that mentions Vitamin D, because some claims about Vitamin D were refuted in the '90s. I was suprised to say the least.
