Doctor T. E. Woodward's legacy: from typhus to typhoid fever.

Dr. Theodore E. Woodward was one of the early giants of infectious diseases research who set the groundwork for the field. He was the first to evaluate vaccines against typhus, employing volunteers to test the effectiveness of the vaccines. This led to the evaluation of chloramphenicol for the treatment of rickettsial diseases and typhoid fever. Subsequently, he was influential in establishing a unique volunteer unit in Maryland in which a wide range of vaccines were evaluated.
