So when I said "Are you sure you're not thinking of some trial or other?" you meant to say, "Yes."
Because that's a trial. It's not an approval. It's not a emergency use authorization. It's a trial.
And it's also a trial that's not recruiting, and appears to have been largely abandoned, since it lists actual enrollment as of October 19, 2021 as 31 people, against their original estimate of 300.
All of which means you're not going to get a 'an approved cockatil by the FDA for onsetting Covid is Ivermectin, Vitamin C, D and some antibiotic I cannot pronounce nor remember' in the ER.
