Hopes pinned on HIV vaccine for 2017


What's likely to be the medical breakthrough in 2017?

There is increasing hope that a vaccine will emerge to prevent HIV. It would work by preventing HIV from taking hold of a person's immune system .

The vaccine - known as SAV001 - is designed to work by exposing the immune system to a safe "deactivated" form of the virus. This then "teaches" the immune system to produce antibodies that can fight HIV. Phase 2 trials, involving around 300 people, in order to see if the vaccine works as hoped, are planned for thsi year.

The number of people living with HIV has significantly increased globally, largely due to the expansion of antiretroviral therapy (ART). Around 39m people globally were living with HIV in 2015, as compared to 28m in 2000.
