Overview

Medical researchers have spent billions of dollars and many decades trying to develop an HIV vaccine but have, thus far, failed. Why is an HIV vaccine so elusive? This news brief from March 2007 explains how HIV's rapid rate of evolution challenges medicine and describes a new discovery that may allow vaccine developers to sidestep that evolution.
