Canadian researchers have created a vaccine and they believe that it can prevent HIV. They will start clinical trials on humans in January as it is approved by U.S. Food and Drug Administration. Researchers can’t be sure if the vaccine works before the trials but they are positive. Even if it is, it will take about five years for the vaccine to go on the market. The SAV001 vaccine uses dead HIV-1 virus and it is altered genetically to be non-pathogenic. The number of people with HIV at the end of 2010 was 34 million according to the United Nations Program on HIV/AIDS. The number is increasing year by year and this vaccine gives hope in both HIV-positive and HIV-negative people.
