TV Journalist: "So, Dr. Krippin, give it to me in a nutshell."
Dr. Alice Krippin: "Well, the premise is quite simple, um, take something designed by nature and reprogram it to make it work for the body rather than against it."
TV Journalist: "You're talking about a virus?"
Dr. Alice Krippin: "Indeed, yes. In this case the measles, um, virus which has been engineered at a genetic level to be helpful rather than harmful. Um, I find the best way to describe it is if you can... if you can imagine your body as a highway, and you picture the virus as a very fast car, um, being driven by a very bad man. Imagine the damage that car can cause. Then if you replace that man with a cop... the picture changes. And that's essentially what we've done."
