It's great to see people asking for citations. I just wish that sort of mentality existed in the everyday world.
At the moment newspaper articles, tv news reports, etc can all get away with discussing science (and science-related topics) with citing ANYTHING.
I'm not saying it'll solve the vaccine crisis, but in the long run, I think the key is getting citations for statements of facts into public discourse. (then you have to worry about the quality of the stuff cited, but that can be the next step).
