title: Optimism is growing as researchers move toward an AIDS vaccine.
abstract: Slow to start, the race for an effective AIDS vaccine now has more than 20 contenders, including some novel approaches that incorporate genetic engineering and the use of vectors, such as a canarypox that doesn't cause disease in humans. Researchers and public health officials say they are more optimistic than ever about the possibility of bringing an AIDS vaccine to market.
