Mass shooting in the middle school Vladislav Ribnikar in Belgrade

Never heard of that one. As far as I understand it, it's the flawed responses to the Semmelweis'es findings (by Levy...) that led to evidence-based medicine. Scientists of the time were responding to the Semmelweis'es findings by trying to make his conclusions look unlikely (that the quantities of the poison are implausibly small) and by pointing the perceived flaws in the Semmelweis'es study, instead of attempting to make a better study.

I’m sure there’s lots of things I’ve heard of that you haven’t.

And I'm also sure I've heard a lot of things that you haven't. Yes, there were people way before Semmelweis who rejected blood-letting on the grounds that studies show that people who have been bled do not survive at a higher rate than people who haven't been, but their philosophy of following the evidence wasn't mainstream in medicine all until the end of the 19th century. Levy and other people objecting to Semmelweis'es findings were not following the evidence. Following the evidence would be to either accept the Semmelweis'es findings (as they are the best evidence available) or to attempt to make a better experiment.
