I can vouch for this. I'm a horse owner so I have ivermectin on my shelf at all times. I've used it on my horses for 30 years. I was 100% comfortable with it after reading the myriad of studies, and there are even more results now. This January, my hubby & I came down with Covid, after visiting friends who tested positive right after. We had all the symptoms, loss of smell and taste, etc., and it was a whopper of a flu, unlike anything before, we were very sick. We took ivermectin for 5 days, one dose per day by weight. We felt better within a couple days and were completely fine by the end of 5 days. Thumbs up. I'll take it again for every virus that comes along, as needed. It works on EVERY VIRUS.
