December 1, 2011 |
Today is World AIDS Day and I was gloomy thinking about what a big problem HIV is. But research into a potential vaccine against HIV could be good news.
Scientists injected mice with DNA that makes cells produce protective chemicals to fight off the HIV virus.
Gene therapy has its problems though – new DNA can’t be turned off if the body reacts against it. This approach will be tested on people in the next few years to see if it really could stop HIV.
