Health-Mosaic vaccine is first to tackle HIV's huge genetic diversity.

An HIV vaccine that could outwit the deadly virus could undergo human trials in as little as a year's time, scientists say.
The 'mosaic vaccine', which is being designed by an international team of investigators, works by being able to adapt to the virus as it mutates.
HIV's ability to evolve rapidly is what lets it dodge current drugs.
Bette Korber from Los Alamos National Laboratory in New Mexico, is one of the scientists who has worked on the project for 20 years.
She said: 'We're in the evolutionary fast lane studying HIV.
'If you give just one drug, HIV evolves away from it. That why treatments involve three or four drugs at once.'
The HIV virus, which is largely made up of proteins, causes AIDS - a disease that destroys the body's immune system leaving sufferers vulnerable to infections and tumours. The disease killed 1.8million people worldwide in 2009.
