Amazing news, "Dr. Louis Picker of the Oregon National Primate Research Center, whose study appear in the journal Nature, said he thinks it will be possible to have a vaccine ready to test in people within three years." While there have been many claims in the past about being able to hold HIV/AIDS at bay with a cocktail of drugs this is the first time an experimental vaccine has shown these kinds of results. With further tests and refinement over the next three years I expect that before 2020 we will have a fully functioning AIDS vaccine something that would truly change the world. AIDS has killed some 25 million people and infects some 33 million a viable vaccine is clearly more desirable than a cocktail of drugs one must take everyday. "Picker and colleagues use a relatively harmless virus called cytomegalovirus (CMV) as a transport system to take the experimental vaccine into the body." This is yet another example of using nature to fight against the worst pathogens, by using a virus already common amongst the human population this lowers the risk of secondary infections, the building up of tolerance o the drugs, and also hopefully will prevent HIV/AIDS from becoming resistant to it. "The breakthrough here is in using a viral-delivered vaccine that persists -- essentially using an engineered virus to thwart a pathogenic virus," said Robin Shattock, a professor of mucosal infection and immunity at Britain's Imperial College, who was not involved in the research."
