The promise of an HIV vaccine

A vaccine to prevent HIV has aced clinical testing, according to Canadian researchers.
The team, from the Schulich School of Medicine & Dentistry at Western University, says the first phase of testing not only succeeded, but boosted the production of antibodies in patients it was tested on.
SAV001, one of only a handful of HIV vaccines in the world, is based on a genetically-modified 'dead' version of the virus.
“We infect the cells with a genetically modified HIV-1,” team leader Dr. Chil-Yong Kang told Ontario Business Report. “The infected cells produce lots of virus, which we collect, purify and inactivate so that the vaccine won’t cause AIDS in recipients, but will trigger immune responses.”
U.S. clinical testing began in the in March 2012, looking at HIV-infected men and women between the ages of 18 and 50. Half the target group was administered a placebo, while the other group was given SAV001. The first phase of trials wrapped up last month, with researchers optimistic about the vaccine's future.
