Its clear everything is just a big mystery still to you. Its not to most of us. The public will demand that an approved technology that works will be used to treat their GBM. Its not approved at the moment but it is well on its way. Of course everything hangs on approval first. "Hard to make" is a barrier they've already crossed. It can be made, and it will be made. But please do continue being ultra negative about every aspect of this vaccine/treatment.
