Once we stop politicking foolishly for, or against potential solutions/tools to help fight this thing, we'll be MUCH better off.
Are you completely informed, and/or being completely honest when you said the manufacturer says the drug is "useless"? Did the manufacturer offer a study, data, or especially a large peer reviewed study supporting such a statement? If they didn't, do you trust what they said, or consider WHY THEY SAID WHATEVER IT WAS THAT THEY SAID???
This drug may or may not help one whit with COVID, but it has been prescribed all over the world for many years, and prior to COVID, it has always been touted as a "miracle drug". It won it's discoverers a Nobel prize, and yet now it's being denigrated, and mis-positioned as a pure veterinary medicine due to the narrative and politics associated with COVID, and the desire to only have a single tool to manage COVID, (i.e. the new mRNA vaccines). It's sad that most are not informed enough, or aware/perceptive enough to see the manipulation and deceit being used to thwart any tool besides the vaccines.
The use of Ivermectin arose because you had doctors in other parts of the world, notice that those who were taking it seemed to do better, so they offered it up as a potential treatment. People should listen to their doctors, inform themselves and such, but what's happening is super sad. I simply want complete honesty and openness, and to have EVERY viable tool that might be used to combat this pandemic, to receive a fair and honest evaluation before it's dismissed. Don't buy into misinformation so easily.
