An experimental vaccine prevented HIV infections for the first time, a breakthrough that has eluded scientists for a quarter century.
A U.S.-funded study involving more than 16,000 volunteers in Thailand found that a combination of ALVAC, made by Paris- based Sanofi-Aventis SA, and AIDSVAX, from VaxGen Inc., of South San Francisco, cut infections by 31.2 percent in the people who received it compared with those on a placebo, scientists said today in Bangkok. Neither vaccine had stopped the virus that causes AIDS when tested separately in previous studies.
