Lining up? Not necessarily.

But it seems almost certain to me that at least some people feel safe thanks to taking ivermectin (while distrusting mainstream vaccines), and those people would turn eventually to the vaccines if those were the only perceived path towards C19 safety.

Perhaps on the margin some would, but I suspect most would fall into the "natural immunity" camp.

So in my mind, we need to weigh the damage done by blocking safe ivermectin use for some number of people to the damage done by a much-smaller number of people remaining unvaccinated when they otherwise would get the jab.

Seems like it could go either way depending on your specific assumptions.

One doesn't imply the other, but it is certainly happening. People are using (being led to use) ivermectin as a prophylactic against covid, an alternative to the vaccine.

I don't know what this is supposed to mean, but a close family member took ivermectin instead of being vaccinated, and caught a serious case.

It's pretty simple: had ivermectin not existed, would that person have gotten vaccinated?
