Well there's no way to convince the disbelievers but Ivermectin is already a cure for covid, weak and imperfect but it definitely does something. I know and believe only because it personally saved me from death's door.
Don't try mentioning this on twitter or facebook though, you'll get your account blocked/banned.
Funding for a more targeted and powerful cure definitely should happen but there is something really really weird in life when you see something being buried that you know is different than the official stroy.
Doesn't help that every quack is coming out of the woodwork to try to cash in on it somehow, not by profit from the drug itself but their only 15 minutes of "fame". But there has to be someway to fix that signal-to-noise ratio when it comes to saving people's lives.
