International HIV Vaccine Trials Discontinued
On September 18, 2007, the Data Safety Monitoring Board for the STEP HIV vaccine study reviewed interim trial data and concluded that the vaccine being tested could not be shown to prevent HIV infection or affect the course of the disease in people subsequently infected with HIV. All study sites have been instructed to stop administering the investigational vaccine. Patient follow-up visits will still occur as scheduled pending further analysis of the data.
