RT Journal A1 ANDERSON RJ T1 BCg vaccination JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1949 FD August 1 VO 78 IS 2 SP 280 OP 280 DO 10.1001/archpedi.1949.02030050291014 UL http://dx.doi.org/10.1001/archpedi.1949.02030050291014 AB To the Editor.—In the article, "BCG Vaccination in Chicago," by Dr. Robert A. Black in your journal of March, 1949 [p. 381] there appears the following statement, "At present, the Tice Laboratories have been designated as the central laboratories for BCG production for the United States Public Health Service." This letter is occasioned because this statement could easily be misinterpreted.The Tice Laboratories have been one of the sources of the BCG used by the Public Health Service in research on the vaccine. However, the Public Health Service is also receiving BCG from the Pasteur Institute, Paris, State Serum Institute of Copenhagen, Division of Laboratories and Research of the New York State Department of Health, Albany, and the Pennsylvania Department of Health Laboratory at Henry Phipps Institute, Philadelphia. All of the aforementioned laboratories have been most cooperative and helpful. There is no officially designated central source of the vaccine.
