Your claims about vaccine trials are not true. I’m not an expert and don’t have time to go and find citations to argue each of your points one by one, but I’ve read enough studies to know that vaccine trials aren’t nearly as sloppy / poorly designed as you believe.
For example, even when speed was extremely important and everyone was trying to get Covid vaccines out as fast as possible a few years ago, they still ran large randomised placebo-controlled trials (in places with high infection rates so they could get good comparison data relatively quickly).
So please stop spreading false claims about this stuff / spend time actually learning the facts. Claims like these do real harm by undermining trust in vaccines and helping fuel avoidable outbreaks of diseases like measles.
