Canadian researchers from the University of Western Ontario in claim they have developed a promising HIV vaccine, which has received the green light by U.S. FDA officials to begin testing on humans.
Unlike other attempts to create a "cure," this experimental medicine uses the entire HIV virus to create a "non-pathogenic" version of the microbe, which doesn't cause HIV in recipients. Instead, the vaccine primes the body's T-cells to destroy any cells that become infected with HIV. This same strategy has been applied to other diseases like polio, rabies, hepatitis A and influenza.
For instance, a large study revealed that an experimental vaccine only helped protect against infection in about one-third of recipients. Those researchers are still working to improve that vaccine.
