Far from being suppressed, this was covered in the news media when it was first announced and received some minor fanfare. It's interesting from a research point of view, perhaps, but it isn't a feasible treatment, because the procedure (full bone marrow replacement) is too risky, not to mention extremely complex and expensive. The normal AIDS drugs are still the state of the art. Even if you were an AIDS patient with an unlimited budget, you would probably not want this treatment unless you could somehow foresee that the drugs weren't going to work for you.
