The transplant treatment itself, given only to late-stage cancer patients, kills up to 30% of patients. While scientists are drawing up research protocols to try this approach on other leukemia and lymphoma patients, they know it will never be widely used to treat AIDS because of the mortality risk.
Am I the only person who noticed this? Transplant of bone marrow is not an ideal solution. Beyond this and the pain that can come from the surgery as has been discussed, it's probably expensive as hell, so no way will it be available where it is most needed. Is this a breakthrough? Yes. Is it the breakthrough? No.


Anyways to be on-topic, hopefully this "cure" should be distributed faster than the virus.
Did you even read about how it works?
