It's a step forward, but treatment is still a long way off: "Independently of the selected gene therapy strategy, and prior to its potential use in HIV-infected patients, vector technology has to be developed that allows safe and efficient gene transfer followed by reliable transgene expression in target cells" Gene therapy isn't possible yet because we still can't control where the transgenes get inserted into the human genome. There's the risk of disrupting oncogenes/oncosuppressors, and the probability of getting cancer would be high.
