His goal was to create an antidote for the virus, however he was faced with many challenges along the way. The FDA states that to have a drug approved it has to be proven effective, to prove that the drug is effective there must be medical trials run on an animal before it can be used on humans. The FDA wants to see many factors in the animal test subjects; first a progression of events/ symptoms that mirror that of human ones, as well as a dose of the virus the same as the dose which would effect a human, and finally the same route of exposure that a human would experience. This is where he is confronted by the first issue. Smallpox is very unique because it only has one possible host: humans. So how do you get a drug approved if it can not even have an animal host to test on? For Jarhling to begin his research he must first find a way to infect a monkey with smallpox. The virus at first would not take in the body of monkey, but finally after administering the virus at a highly concentrated dose through both aerosol and intravenously he saw results. At this point there are slides of the paperwork and lab reports from the study showing on the screen, this backs up the testimony of Dr. Jarhling and provides logos. Coming in on day three of the experiment almost every monkey was down, the level of hemorrhage was unlike anything he had ever seen. During this part of the video photos of monkeys paws and faces come on the screen, showing the signs of the smallpox virus, including the infamous tiny bumps that cover the skin. This draws on the logos of the argument presenting reliable information and showing images of real results. After finally having an infected subject he could start his real work; curing the
