They are going to stop studying so they can start studying the issue? Ah well, this is the level of ‘science’ we’ve come to expect in the pandemic.
I don't know much about this particular case, but I think, in general, a trustworthy review needs to be conducted by an independent body with genuine power (edit. and desire) to order things to halt permanently if they can not be made safe enough (and then there is a separate question of who makes the call "what is safe enough").
This is hard. If there isn't the right incentive they can decide nothing is safe enough. This ensures safety now, but it means that if a cure is possible it won't be discovered (or anything else useful from the research). The FDA has been accused of needlessly holding up useful drugs on this grounds (I'm not going to comment on if true or not)
Its not rocket science.
