Clinical trials

Clinical trials are experiments in where new treatments or diagnostic methods are test in people to see whether or not the new drug will work with them the way it's supposed to. They do it so that neither the patient or the doctors giving the treatments know if it is the real drug or if it is just a placebo pill (sugar pill). This is called double blind because two parties don't know but there is always a third party that will know whether or not the drug has worked or not. The reason they test these experimental drugs, vaccines, and other types or therapy with double blindness is so that it is unbiased. It needs to be unbiased so that the company making the drugs can't say that it really helped someone when it didn't.
