Buildings 29 and 29A are nationally significant to the history of medicine and public health because within the laboratories of Buildings 29 and 29A, the National Institutes of Health (NIH) and then the Food and Drug Administration (FDA) staff helped to conquer some of the deadliest infectious diseases. In their regulatory role, they had the national responsibility to license vaccines, antitoxins, blood products, and other biologics to ensure their safety and effectiveness. To support this mission, they did scientific research which resulted in the development of important standards and even new vaccines. Some of the most well-known scientists of the 20th century worked in these buildings, as well as the key administrators and others who supported their work and the mission of biologics regulation and 22 of them are profiled here in the biographies section. This online exhibition will share information about the research, regulations, and work conducted in these two laboratory buildings between 1960 and 2014. A variety of diseases, vaccines, and other biologics are discussed, with links to articles and other websites for further research. While the buildings are no longer in use, the legacy of their exemplary staff and their important work endures.
