Then they infused you with something called Newcastle virus, a disease that is deadly to chickens but not dangerous to humans. The presence of the virus caused a response in the body’s immune system, which they studied by removing cells after five days. The hope was that whatever defense your own body created, they could boost by loading the altered cells into the previously removed ones, then changing them in the lab, millions of them, then injecting them back into your body in a vaccine. The changed cells would, in theory, stimulate your immune cells to attack the DIPG tumor.
