My mother got Covid last week (she's 72). She immediately took Ivermectin (and vitamin D, C, Zinc) as instructed. She got sick, but it was never bad and lasted a total of three days. Now she is perfectly fine, says she feels great. Its anecdotal, but I was never worried. All the data suggests that those four things together are a total defense against SARS-CoV-2. (If you can also add HCQ, I'd recommend it.)

This review paper and meta analysis from the American Journal of Therapeutics (a well respected world wide journal) has an shining recommendation of Ivermectin. I think this report from such a journal might have a substantial impact going forward.
