Yay! More fantastic news for the fight against HIV and AIDS is on the way.

Canadian researchers have received approval from the United States' Food and Drug Administration to begin testing a preventative HIV vaccine on humans this January.

The "unique" treatment uses dead HIV-1 virus to infect cells which will then be collected, purified and inactivated. Although it sounds scary to have a deadly virus injected into your healthy body, the vaccine is genetically engineered to be non-pathogenic, which means it won't cause HIV.

Dr. Chil-Yong Kang, the leader of the research team at the University of Western Ontario, has been working on the vaccine since 1987 and hopes to save the lives of millions, saying:

“FDA approval for human clinical trials is an extremely significant milestone for our vaccine, which has the potential to save the lives of millions of people around the world by preventing HIV infection.”

After all the hard work Dr. Kang has put in developing a vaccine that can potentially change the world, we sure hope he succeeds!
