HIV infection stopped in its tracks

摘要

FIVE people with HIV are currently free of detectable virus -and daily drugs - thanks to a new vaccine-based therapy. Although it is early days, one participant has been drug-free for seven months. Most people with HIV need to take antiretroviral drugs (ART) each day to stop the virus from replicating and causing damage to their immune system. These have to be taken over a lifetime because the virus can hide away in tissues such as lymphoid and gut cells; if ART is stopped, the virus quickly re-emerges from these cells.
