Just a personal anecdote here. I stocked up on Vitamin-I, the horse paste version, early on. "Just in case." Haven't needed it so far.

My sister's family came down with COVID in January. Her kids came through fine, no problems. She and her husband were worse. Her regular doctor would not prescribe Ivermectin. But, she has an extensive social circle, so she asked around. (she's in New York State) She finally found a doctor willing to prescribe it. She and hubby took it, were soon headed in the right direction health-wise.

This weekend my brother in California called! He'd been dealing with 'the coof' for over a week. His doctor prescribed steroids, which didn't seem to touch it. I can vouch for him sounding HORRIBLE on the phone. He was coughing twice per sentence! I was a little concerned about his ending up it the hospital (ie Covid death camp!) because the doc mentioned his "oxygen was a bit low."

He was not able to get an Rx for ivermection. But he had stocked up on 'horse paste' a few months ago at my urging. He HAD it, but hadn't used it! He was a bit nervous about it because his doctor was opposed.

I said "You sound TERRIBLE. Take some TONIGHT before you go to bed! And again tomorrow morning."

He texted me the next day and said he felt incredibly better, the cough had greatly dissipated, and he felt he was on the upswing. Even I was amazed at this quick turnaround! (from the 'horse paste' version, no less!) This was after suffering for over a week with COVID with no apparent end in sight.

I know it's only a sample of two, but it's from my family, and so far Vitamin-I is batting two for two!
