The results cited are based on human studies. Further, Okarma says that the data indicates it is real immunity, which can be easily restored with a booster. But he also speaks to this as a proof of concept, and that the process involved is too expensive to be really viable. Thus, the development of GRNVAC2, which I think uses modified stem cells to impart immunity, rather than training the body's own immune cells to do so. Someone might correct me on that. In any event, this hardly seems like a blind alley; it is exceedingly promising. But yes, it still is out there a ways. It may be new stuff, but it already seems to beat the hell out of the extremely dangerous treatments currently in wide use. We need FDA to step up and accelerate these things, somehow.
