The sponsors of a planned human trial for an AIDS vaccine canceled the project Thursday, saying they doubted the vaccine's effectiveness and noted that the trial could actually put volunteers at risk of acquiring HIV, The New York Times reported.
The trial, called PAVE (Partnership for AIDS Vaccine Evaluation), was to be conducted by a consortium of U.S. agencies and private organizations. It was to have begun enlisting 8,500 volunteers last October to evaluate a vaccine developed by the National Institute of Allergy and Infectious Diseases.
