Many have tried and failed to create a vaccine that could prevent infection with HIV. Now, Canadian researchers say they're working on one that takes a different approach.

Researchers from the University of Western Ontario in London, Ont. say they have developed an HIV vaccine that uses the whole HIV virus, unlike other attempts that have used just certain genes or proteins from the virus.

The virus has been genetically engineered to be "non-pathogenic," meaning it can't actually cause HIV in recipients. The idea is the vaccine would prime the body's T-cells to destroy any cells that might become infected with HIV.
