I just came across this website. It was linked to by Robert Kennedy, Jr. in catsfive's recently-stickied post.
The authors of the site have compiled a huge amount of scientific data for various medications used in the treatment and prevention of Covid. These include Ivermectin, Zinc, Vitamin D, Remdesivir, and many others.
I strongly recommend giving it a perusal and a bookmark. It is a very useful reference should you or anyone you know get Covid, and would be effective for evidence-based argumentation, if the other side was actually willing to examine the evidence.
Enjoy.
I've seen that time and time again. I'm sorry you're having to deal with it. Just because someone has gotten the shots doesn't mean that early and prophylactic treatments are no longer needed or efficacious. The brainwashing is real.
