Earlier this year Merck the manufacturer of Ivermectin issued this [0] statement saying that Ivermectin isn't useful for preventing/treating Covid-19 and people shouldn't take it. Some people explained that with the fact that Ivermectin is cheap and they want to develop a more expensive option. I didn't take this seriously, just another conspiracy theory. But now they are coming out with a $1000 per dose solution. According to the FDA [1], the use of Ivermectin for Covid-19 is still being studied and they refer to ongoing trials. Now some people with actual subject matter expertise will know more than me but afaik we haven't completely ruled out Ivermectin for the treatment/prevention of Covid-19, have we? If not, could there be some truth to the allegations that Merck somehow is stalling the Ivermectin studies?
