Science on this is great. However, don't parrot this to your friends until you see it replicated somewhere else (preferably somewhere not governed by ivermectin-peddling populists) and confirmed in a double-blind random-controlled trial (which this doesn't even get close to). After all, no reason to hold this stuff to a lower standard than the anyone want to hold the vaccines to (regardless of whether they realise these standards were already met there).
