I'm not a doctor, nor do I play one on T.V... Heh
I did work in a para-medical field at one time, though.
I can tell you from experience that one of the biggest challenges practitioners face is patient compliance, getting patients to do as instructed without deviation. A common example would be discontinuing an antibiotic protocol before the allotted time. Some of these treatments, such as Ivermectin, do have data showing they can achieve a level of success IF the proper protocol is followed precisely. This is where the trouble begins. The protocol is complex and requires strict adherence. When used correctly, it's a relatively safe drug. When used incorrectly it can be deadly. If, for some reason, you are inclined to use one of these treatments, make absolutely certain you seek medical guidance and follow the instructions to the letter. These treatments do offer value to places that may be unable to use the vaccine due to logistic difficulties or lack of funding. Still, by far, the best option available is to get vaccinated as a prophylactic measure. Despite the misinformation circulating on the net, these vaccines have been extensively and thoroughly tested. They are relatively safe (everything has an element of danger.), readily available, inexpensive(Free in U.S.), and easy to administer.
And remember, "You can't have your pudding if you don't eat your meat.".
