Hydroxychloriquinine + Zinc also works. It worked on my BIL. Hydroxy opens the cells to allow zinc in. Then when the Covid attacks the cells, it bonds with zinc committing suicide. He had Covid last year, and later he tested for antibodies, and he had none. So yeah he could get it again, but it killed it.

Both hydroxy and Ivermectin are cheap drugs that drug companies make very little profit on. These two drugs are what most third world countries are using to fight this virus. Their death numbers from Covid are way down. All except Peru which is very high for some reason. Since it attacks the nose and lungs and they live at very high altitudes, lack of oxygen may be why it is killing so many there.
