“16,000 in Largest HIV-Vaccine Trial”

Nation (Thailand) (www.nationmultimedia.com) (07/16/01)

Thailand’s Public Health Ministry reports that 16,000 HIV-negative volunteers between the ages of 20 and 30 years old will participate in a phase III trial of an experimental HIV vaccine.  Participants in the three-year study will undergo a six-month regimen of ALVAC-HIV (vVP1521) shots, boosted twice with AIDSvax (rGP120 B/E), designed to stimulate the humoral antibodies and cell-mediated immunity needed in order to block HIV.  ALVAC is made by inserting a portion of the HIV gene into the canary-pox virus.  Trial volunteers will be selected from eight districts within the high-risk provinces of Chon Buri and Rayong, where the infection rate of HIV is especially high.  Phase III is a collaborative effort between the Thai health ministry, Mahidol University and the U.S. Army’s office of the Surgeon General.  The Phase I and II vaccine trials for safety and immunity efficacy were conducted jointly by Mahidol University, Siriraj Hospital and Chiang Mai University Research Institute in Health Sciences.
