HIV is a virus that causes AIDS. There is no cure for HIV, but there are many treatments available that can prolong a person's life. In the late 1990s, researchers began work on a possible HIV vaccine. However, it has been difficult to develop a vaccine that is effective in humans. In 2013, scientists developed a vaccine using gene therapy. The vaccine was designed to help the body fight infection by targeting the virus directly. To date, this vaccine has been successful in trials in monkeys and human cells. There is still much research to be done before this vaccine can be tested in humans, but it is hoped that it could provide a cure for HIV within the next few decades."
