Dr. Anne R. Yobs
CDC Physician Who Continued the Tuskegee Syphilis Study in the 1960s
CDC physician who reviewed and supported the continuation of the Tuskegee study in the 1960s, even as ethical standards in medical research were beginning to evolve
Overview
Dr. Anne R. Yobs was a physician at the Centers for Disease Control (CDC, then the Communicable Disease Center) who played a role in continuing the Tuskegee syphilis study during the 1960s. By the time Yobs became involved, the study had been running for approximately three decades and penicillin had been the standard cure for syphilis for nearly twenty years. Yobs reviewed study data and supported the decision to continue the non-treatment protocol at a time when the Nuremberg Code (1947) and the Declaration of Helsinki (1964) had already established international standards for ethical human subjects research. Yobs was involved in the 1969 CDC review of the study that concluded it should continue to its "endpoint" (the deaths of all remaining subjects and their autopsies). This review, which occurred after Peter Buxtun had already filed his first formal objection in 1966, represented one of the final institutional decisions to perpetuate the study before its public exposure in 1972. Yobs's participation illustrates how the study was sustained not only by its original architects but by successive generations of public health professionals who inherited the project and chose continuation over ethical reckoning.
