RE: because if Ivermectin use were widespread, then there would be no need for lockdowns, vaccines, or masks.
The key words are “if” an “were”.
The fact that it isn’t doesn’t show that it is snake oil. The opposite is — THREATENING DOCTORS with delicensing for prescribing it IS the snake oil.
In fact, in places where its use is widespread, hospitalizations and fatalities have dropped.

Yet no one has conducted a randomized double-blind trial showing its effectiveness. Why do you think that is?
And this paper says nothing about Ivermectin’s efficacy, only it’s safety when used for who knows what.
