Trials of experimental HIV vaccine halted in Africa due to ineffectiveness
Trials of an experimental HIV vaccine in Uganda, Tanzania and South Africa were stopped early after preliminary data showed the vaccine would not be effective in preventing infection, the program's chief investigator said today.
It is the latest blow to efforts to find an effective vaccine against the virus, which has so far killed 40 million people worldwide. Another 39 million of them are living with HIV, most of them in Africa.
The vaccine trial, part of a wider initiative that began in December 2020 with 1.512 healthy people between the ages of 18 and 40, was due to end in 2024.
