A team of researchers at the Los Alamos National Laboratory in New Mexico say they could begin human trials of a new HIV vaccine within a year. This new vaccine, called a “mosaic,” is comprised of information from hundreds of thousands of HIV fragments in the form of protein sets. Animal studies show that this vaccine can cue the immune system to respond to HIV gene mutations. While traditional vaccines stimulate the body’s immune system in response to virus proteins, HIV mutations are too fast and numerous to be quelled by just one protein sequence.
