A Cure for HIV?

A man appears to have recovered from HIV. Doctors want to study his immune system, which could provide a cure for the killer virus.

Londoner Andrew Stimpson, 25, was diagnosed HIV positive in 2002. But in October 2003, new blood tests found him HIV negative.

Further testing confirmed his HIV free status. Stimpson, who was born in Largs, told BBC news he was one of the luckiest people alive.

Unusually, Stimpson did not take medicine after the first diagnosis. He continued to feel well, according to The News of the World.

However, his results are disputed among some AIDS experts, who think the tests may have been botched or mixed-up.
