Ivermectin has shown great promise not only treating symptons of covid (5000% reduction in viral load in one paper) but also as a prophylactic. The small studies released recently suggest up to 83% effectiveness as a prophylactic. Of course larger RCT will need done, but fat chance of that with the economic incentive for big pharma and their politcal cronies and the weird political push to get EVERYONE vaccinated.

It saved my ass. My regular gp's advice was just to live with long covid for the next 12 months or so until it went away. He couldn't prescribe it so I found the horse paste and got better.
