"We're looking to see if this vaccine can prevent HIV infection or at least alter the course of the disease once infection has occurred," said Dr Tony Kelleher, of the University of NSW. He said that the drug in question could potentially halt the infection, but cannot change the disease once it has affected a person.
"This vaccine is not being tested for therapy, and we don't want to give people false hope," he said. "The therapies for HIV have improved remarkably over the past decade, but the curative qualities of the tested drugs are not there, so that means HIV therapy for life at the moment."
