New tests raise hopes of HIV vaccine


A vaccine for HIV could be close, with tests showing a 66% reduction in HIV infection after treatment with a new drug. Previously, drugs have only been able to reduce infection rates by around 30%, and have been discontinued.

The recent tests showed positive immune responses in 400 healthy adults, and lead to only 33% of rhesus monkeys contracting the disease after being exposed to it 6 times.
