Many people see an effective preventive AIDS vaccine as the best solution to the HIV/AIDS pandemic. Ten years ago many scientists had hoped that a vaccine would be available by now. Most scientists are still optimistic that vaccines will be developed and many candidates are being tested. Strategies to implement HIV/AIDS vaccination need to be developed to be ready when vaccines do become available. The nature of those programs will depend on the characteristics of each vaccine.

The answers to these and other questions will help determine issues such as: What will be the impact of the vaccine on the epidemic? Who should be vaccinated?
