Callender's supervision, guidance and research in the school contributed directly to the achievement of the lowest sick rate of any army in the history of war. His initiative and effort were largely responsible for the creation of the course in tropical medicine and for the development of extensive research activities at the Army Medical School in 1941 before Pearl Harbor. As a result of the typhus vaccine developed in 1942 not a single United States soldier died of epidemic typhus fever."
