one of the strongest defenses we have against disease is our immune system. one of the first things that a brain tumor has to do in order to survive in the brain is that it has to make itself invisible to the immune system. the experimental drug isn t like a flu vaccine. it doesn t keep you from getting cancer. it uses cells from your own body to encourage your immune system to mount a targeted aggressive defense. we had 16 patients that were newly diagnosed with this. typically without the vaccine only 12% of patients would make it to the five-year mark. this small group, 16 patients, did more than three times better. all of the 16 patients, 6 of the 16 are alive and disease free. 3 of those 6 are alive and disease free out past five years. we met two of those three patients. mary wong lee and michael wolf. when i tried to spell for him i think he realized there was something not right. went to work with a bad headache, had a seizure at the office. collapsed
