None of this is correct. Both of these drugs were part of the conversation long before a vaccine was available, and at least withe Ivermectin the proposed usage is as a prophylactic or as soon as you see any symptoms. Not once you are so sick that you need to go to the hospital. To be clear, I'm not giving any medical advice, just clearing up some incorrect statements.
People were promoting two things: (a) that the economy should be fully re-opened because Ivermetctin/HCQ would solve the problem of hospitalisations and (b) that vaccine development was as such unnecessary.
Both were completely wrong. Ivermetctin/HCQ has being actively used around the world for over a year and it has not "solved" the issue of deaths due to COVID.
It's not. It is a supplement to the vaccine for people who are already hospitalised.
