The reason the treatment is not FDA-approved,is because it is untested in clinical trials. For clinical trials, you’ll need a Test Group (who will be given the treatment being tested) and the Control Group (who is given a placebo, and hence is untreated). These tests are “double-blind”, so that neither the test subjects or the researchers know who is getting the meds, and who is getting placebos. For the test to then proceed, you have to expose both groups to Ebola, so the researchers then record their observations. How many get sick? How sick? How fast? Mortality? Side effects? For the test results to validity, there needs to be a minimum sample size.
Wanna’ volunteer for THAT drug trial?
