I also find it interesting that the only "studies" the powers that be will quote are the negative ones, the one you stated being one of them, and the very early invitro study where high rates were used. They can't seem to find any of the later more positive ones, or if they are brought up they say they are too small of sample or find other reasons to dismiss the findings.

There are now around 80 studies that are at some stage of completion. It will be harder and harder to ignore as more of these studies are finished and published.

My suspicion is that the powers that be want to minimize any effective treatments till they get all the people they can vaccinated. After all, if there was cheap effective early treatment, how many more people would opt out of a vaccine?
