There were no trials in Australia. He's on instagram, not twitter. Why would he even know of or think of DCVax-L. Don't be an idiot. It likely was not even on his panoply of options. Further, he's a doctor. Many doctors think they know exactly what to do and what ails them. He has probably recklessly, made himself a guinea pig for his own concoction. Very Australian, do it yourself, in the outback. But it doesn't say anything at all about not choosing something he never mentioned and probably did not think would be available any time soon and more likely is not that aware of if at all.
