No it doesn't.
Maybe something on social media but not a single one of my wife's colleagues at the hospital nor any other scientist would have turned down ivermectin (as an example, there were many other theories besides that one drug) if it had shown any sign of doing good for their patients.
There were routine talking about alternate therapies among the scientists/doctors/researchers about these topics. You can search for the UCSF Covid Grand Rounds on youtube and watch the history of their open discussions as research was routinely presented from all over the globe on the various items.
I code for a living and have no idea about this stuff, but my wife's goal is to make patients better and she would watch the grand rounds (or similar) every time and I'd listen from another room. Not a single alternate treatment wasn't discussed and evaluated.
