Developing a safe and sufficiently effective HIV vaccine is essential if we are to achieve a timely and durable end to the global HIV/AIDS pandemic. The path to an HIV vaccine has not been—and will not be—an easy one. In the 27 years since the first HIV vaccine clinical trial was performed, we have been disappointed by many promising investigational vaccines that ultimately proved ineffective in clinical trials, encouraged by a large-scale study in Thailand that demonstrated for the first time that an HIV vaccine can provide a modest level of protection, and, heartened by recent important discoveries about antibodies that may be capable of protecting against a wide range of HIV strains.
NIAID conducts and supports research—at NIH, throughout the United States, and worldwide—to study the causes of
infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News
releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at www.niaid.nih.gov.
