HIV – how close are we to a vaccine or a cure: Stem-cell transplants have freed seven people of the virus, but researchers say most long-term interventions remain a distant prospect.
Challenges and advances in HIV treatments: It was recently announced that a seventh (7th) person had been “cured” of HIV using a stem-cell transplant, a method that is effective in patients with both HIV and cancer that require bone marrow transplants; however, unsuitable for widespread use due to potential complications. Current HIV research is concentrated on long-acting injectable treatments, vaccines and gene therapies aimed at controlling latent reservoirs of infected cells or targeting the CCR5 receptor that HIV uses to enter cells, with some approaches in early clinical trials.
