Possibility of a new HIV vaccine is positive because scientists have found a new and a rare antibody b12. Co-author of a paper published in the Nature on the study of b12, Peter Kwong, of the National Institutes of Health has found. The b12 antibody provides a key to scientists: its behavior will give the scientists a precise roadmap and idea on which to develop potential vaccines that would replicate b12’s actions. Another advantage of b12 and its target protein (which is called HIV gp120): while the HIV virus is known to mutate again and again, the HIV gp120 protein is stable throughout the existing strains of the virus.
