Scientists think it will still take decades to develop an HIV cure. It’s considered unethical to do a stem cell transplant on someone who does not have cancer because the treatment is so toxic. HIV can also hide in non-replicating immune cells, even when the disease is suppressed by antiretrovirals. First diagnosed with HIV in 1990, the man had been taking antiretroviral drugs since 2005 and received a stem cell transplant two years ago to treat a rare type of blood cancer.It’s rare for someone with HIV to go into remission and be considered “cured,” but a European man may be the sixth to do so. While the first five received the transplant from a donor with a rare genetic abnormality that is resistant to HIV, this man did not, Is there a cure for HIV?
