Today, there are medical treatments that can slow down the rate at which HIV weakens the immune system, but currently there is no cure for the disease. Even with extensive prevention efforts from multiple government and private agencies, HIV is still spreading worldwide. One country in particular, Thailand, has been experiencing an HIV epidemic since the 1980s, with an estimated 800,000 of the 60 million people in the country infected. The vaccine composition tested varies from country to country, because different strains of HIV are found in Asia than in North America, for example. Designed to stimulate the body to produce antibodies to certain types of HIV, the vaccine is still in various stages of clinical trials.
Further testing is necessary before the possibility of licensure.
