HIV Vaccine Is Possible, Reaserchers Say

Posted: Updated:


An experimental vaccine has for the first time prevented infection with the AIDS virus, a groundbreaking development in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible, according to the Associated Press.

The vaccine cut the risk of becoming infected with HIV by more than 31 percent in the world's largest AIDS vaccine trial of more than 16,000 volunteers in Thailand, researchers announced Thursday in Bangkok.

Even though the benefit is modest, "it's the first evidence that we could have a safe and effective preventive vaccine," Col. Jerome Kim said in a telephone interview. He helped lead the study for the U.S. Army, which sponsored it with the National Institute of Allergy and Infectious Diseases.

The institute's director, Dr. Anthony Fauci, warned that this is "not the end of the road," but said he was surprised and very pleased by the outcome.

"It gives me cautious optimism about the possibility of improving this result" and developing a more effective AIDS vaccine, Fauci said in a telephone interview. "This is something that we can do."
