In the battle to prevent HIV, the United States has officially turned to its northern neighbor for a possible solution.

The Food and Drug Administration (FDA) announced Tuesday that an HIV vaccine developed by Canadian scientists has been approved for human trials, according to the CBC.

Researchers from the University of Western Ontario developed the vaccine, describing it as a genetically modified killed whole virus.

Dr. Chil-Yong Kang, a researcher and professor at Western's Schulich School of Medicine and Dentistry, expressed his delight over the group's work.

"We have gone through so many different challenges to come to this point," he told the CBC. "This is the first time that I feel very happy and comfortable to initiate this human clinical trial. 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."

The vaccine will undergo three phases of human clinical trials starting in January.
