A World First: Vaccine Helps Prevent HIV Infection A world frst: AIDS vaccine cuts the risk oF HIV inFection by 31 percent in large Thai study By MARILYNN MARCHIONE The Associated Press BANGKOK For the frst time, an experimental vaccine has prevented in±ection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent ±ailures led many scientists to think such a vaccine might never be possible. The World Health Organization and the U.N. agency UNAIDS said the results "instilled new hope" in the feld o± HIV vaccine research, although researchers say it likely is many years be±ore a vaccine might be available. The vaccine — a combination o± two previously unsuccess±ul vaccines — cut the risk o± becoming in±ected with HIV by more than 31 percent in the world's largest AIDS vaccine trial o± more than 16,000 volunteers in Thailand, researchers announced Thursday in Bangkok. Even though the beneft is modest, "it's the frst evidence that we could have a sa±e and e±±ective preventive vaccine," Col. Jerome Kim told The Associated Press.

"It gives me cautious optimism about the possibility o± improving this result" and developing a more e±±ective AIDS vaccine, Fauci said. "This is something that we can do." The Thailand Ministry o± Public Health conducted the study. The U.S. Army has long worked with that government and others to develop and test vaccines and medicines to protect troops and the general public. The study used strains o± HIV common in Thailand. Whether such a vaccine would work against other strains in the U.S., A±rica or elsewhere in the world is unknown, scientists stressed. Even a marginally help±ul vaccine could have a big impact.
