I took prophylactic ivermectin for a few weeks, and yes, it had a picture of a dog on the box, because that's the only kind I could find. You won't find human ivermectin where I live because there are no endemic parasites to treat - or at least, they are few. I stopped after getting my first shot - vaccines are the strictly superior version. But the cost-benefit situation was already clear last winter: it has a very good safety profile, and may help prevent and treat early Covid. No reason to ban people for saying that, or at least no medical reason, nor a humanitarian or social one. But it does get one virtual signaling points, because we have to get those heretics to vaccinate, even if we have to burn to the ground everything they might consider an alternative. When they have nothing left they'll realize we wanted what's good for them all along.
