Washington - Scientists who managed to freeze the HIV virus in the act of infecting a cell said yesterday their experiment could lead to a vaccine that would actually work against the virus.
Dr Jack Nunberg and colleagues at the Montana Biotechnology Centre at the University of Montana said they had unfolded a protein the virus used to infect cells, exposing hidden parts. Writing in the journal Science, they said the immune systems of the mice they tested reacted to these once-protected parts of the protein.
