This is the first case I heard of where a brain tumor patient was able to get a treatment under the "Right To Try" laws. I do not know what the costs are (if anyone finds out - please let me know). This is one of the more exciting vaccines. It is made with fresh tumor sample from the patient AND with tumor samples from 3 other people with the same tumor type. The idea is that should allow the vaccine to hit any of the current targets in your tumor, but also prevent the tumor from mutating around the vaccine - since the most common mutations were picked up from the donors!
