Aids vaccine passes early test in humans

PARIS: The three-decade-old quest for an Aids vaccine received a shot of hope on Monday when developers announced that a prototype triggered the immune system in an early phase of human trials. Tested in 393 people in the United States, Rwanda, Uganda, South Africa and Thailand, the drug “raised antibody responses in 100 per cent of vaccine recipients,” Dan Barouch, a member of the research team, said in Paris.
