They were all wrong to bet the farm on vaccines and to put the kibosh on re-purposing other drugs. They didn’t even investigate them! It would have been cheap and easy to do a controlled trial in 2020 with 100,000+ cases a day to test various treatment protocols. Others call the current process the “let them die protocol” and there is some truth to that.
I can’t say with certainty these regimens would work though there is a lot of data that shows they could help a lot, especially when given early. But that’s not really the point. All these hundreds of billions of dollars we spent, and nothing spent on just some simple random controlled tests of generic drug regimens. The system is captured by special interests and politics. That is not following the science.
Now they say the antibody treatments like Regeneron’s may not even work on omicron. I don’t know and did very little research on that.
Did they do clinical peer review? Seems quick for FDA to be saying something like that before they had the chance to review all the data.
