I heard, and admittedly this just might be internet lore, that India stopped utilizing Ivermectin (and probably HCQ) when they started their vaccine program a few weeks ago. Then the CoVid cases spiked up.
And now they’ve started using Ivermectin again, and the cases are going down.
The states in India using HCQ and IVM are suffering a tenth of the death toll of Maharashtra and Delhi where Remdesivir was used in many hospitals instead (WHO/Western recommendations in general).
