Because they don't want people to die. Because they want to see what side effects there are and if it is worth gambling with your life that the side effects won't be worse than the disease.
When anyone says they are "working on" that does not mean whatever it is will be available "in a certain period of time". Many clinical trials are ABORTED because the drug has serious deleterious side effects. Just because a drug begins the trials means nothing. There are stages they must go through and benchmarks they must meet at each stage BEFORE they go to the next stage. The HOAX is so stupid dumb he thinks you develop a drug today you use it tomorrow on the general public. Because he hates science and never pays any attention to it. He was born obtuse and he remains obtuse because he already knows everything worth knowing according to him.
