Attachment 3-A February 11, 1948 letter from Dr. Stokes to Dr. Colin McLeod [Excerpt] 1740 Bainbridge Street, Philadelphia 46, Penna. Dr. Colin McLeod, 11 February, 1948 488 East Avenue, New York, N.Y. Dear Colin: Owing to the importance of our human studies in hepatitis and to the fact that little opportunity was afforded in Washington for full discussion of their rationale, I am writing to clarify some of the points involved. I believe it is important that funds should be available through Congress for the purpose of reimbursing volunteer prisoners who may be sufficiently disabled as a result of the studies to prevent their full return to gainful occupations after release from prison. Such disability, whether partial or complete, is a fairly remote possibility for the viral agents we are now using in the hepatitis studies, but it should be the concern of the Epidemiological Board and of Congress to permit the use of funds for disabilities resulting from studies on other diseases or conditions which are of importance to the Armed Services and for which the study of human beings is essential. This is so important for our work that I am urgently requesting you to make every possible effort toward attaining this objective. I shall be only too glad to assist to whatever extent you desire in any such efforts. In reference to another point in our discussion in Washington, there was also insufficient time to point out certain essential facts relating to our studies on humans, which it was suggested might raise a point of ethics. I wish to be quite clear, therefore, on the following points concerning the use of children in the hepatitis studies by consent of parents or guardians. No study has been initiated except under the provision that the study in our opinion could be of benefit to the individual himself, who is chosen for the investigation. For the studies of mumps in children this provision is more obvious, since it is well recognized that children should have mumps before puberty. The fact that the exposure is a planned exposure and the children are under nursing care from the start of the incubation period provides a favorable active immunization during the childhood years. The importance of contracting mumps prior to puberty is emphasized by the refusal of many schools to utilize ultra-violet lamps in the lower grades for fear cross- infection in mumps, as well as in vari-cella and rubella, might be prevented. It is also a well recognized pediatric practice to plan exposure of children to these diseases before puberty if the opportunity is presented to do so.
