Creator:

United States. Army Air Forces
Hodges, Richard G.

Recipient:

Heidelberger, Michael

Date:

2 January 1945

Description:

During World War II Heidelberger served as a member of the Pneumonia Commission established by the Board for the Investigation and Control of Influenza and Other Infectious Diseases (later the Army Epidemiological Board) under the Surgeon General of the U.S. Army. The Commission, headed by Colin MacLeod, a microbiologist and co-discoverer of the genetic properties of DNA, organized a trial of a vaccine against pneumococcal pneumonia developed by Heidelberger. The trial, carried out among 20,000 trainees at an air base in Sioux Falls, South Dakota, proved that a vaccine made from a mixture of purified capsular polysaccharides from four different types of pneumococcus (types I, II, V, and VII) provided effective protection against pneumonia when compared with a control group which received saline solution, and which had a higher incidence of the disease. As Hodges, who oversaw the study on site, reported in this letter, not a single soldier who had been immunized had contracted the disease, compared with ten who had been given saline solution.
