I'm not uncomfortable lumping a lot of that together as 'medicine'. For instance, we know vaccination in general raises his ire, but he also seems to object to pasteurization. If he remains in a position to be able to ban that practice, it could be a significant driver of health-related issues. And I do think he's in a position to be able to ban or at least substantially punish the practice of pasteurization, vaccination, flouridation… it's unclear how much influence the man will have, but it could be a great deal.
you know that everyone is still getting Covid over and over and over again every year, right?
This one I know is a straight up lie, because I remember where it came from: Trump asked an expert if it was possible to use disinfectant inside the body, was immediately shut down with a simple "no", and dropped it. Audio of the conversation was leaked and immediately twisted into "drink bleach", ignoring everything else about the conversation.
Also UV light treatment actually exists, just not for this purpose. It's a completely normal thing to ask once you learn UV kills viruses.
