The problem with p's and t's is, they gotta do the same research on them, that everyone demands of vaccines. Can't demand 5 years for one and 2 months for another. The African study which is specifically looking for low-cost p's and t's wasn't promising for some drugs and neither are the McMasters 3-nation studies. But researchers are still trying.
Here's one that is in phase 2/3 trials in the US and Africa you might not have heard about, but until now only 200 study participants so who knows the side effects when one is trying to target a few cells and not all cells:

of or with doesnt' really matter if the with makes the original nonlethal complaint deadly; even a broken leg pays the hospital more than a covid isolation admission ;)
FWIW, I know a few people who weren’t treated until they presented with COVID pneumonia.
Lovely, eh? No early treatments were provided. One was even told that there were NO treatments for CoupFlu by the provider the patient first saw.
None of them have been treated with anything other than the z-pack and zinc after they developed their complications.
None of them required hospitalization.
All have recovered, with continuing loss of smell the only lingering issue.
