About The Untreated Syphilis Study at Tuskegee

Background

The U.S. Public Health Service (USPHS) Untreated Syphilis Study at Tuskegee was a study conducted between 1932 and 1972. The study was supposed to observe the natural history of untreated syphilis. As part of the study, researchers did not collect informed consent from participants. They also did not offer treatment, even after it was easily available. The study ended in 1972 on the recommendation of an Ad Hoc Advisory Panel. The panel was convened by the Assistant Secretary for Health and Scientific Affairs, following publication of news articles about the study.

In 1997, President Clinton issued a formal Presidential Apology. In his apology he announced an investment to establish what became The National Center for Bioethics in Research and Health Care at Tuskegee University. Many records can be found in the National Archives.

After the study, sweeping changes to standard research practices were made. Efforts to promote the highest ethical standards in research are ongoing today.

Subjects and participation

Tuskegee community members were aware of the study but thought it was a special government health care program1.

According to the Assistant Secretary for Health and Scientific Affairs' Ad Hoc Advisory Panel's published report, "...the Macon County Health Department and Tuskegee Institute were cognizant of the study."

No women were included in the study. The study was limited to Black men 25 years of age or older. However, as a result of lack of treatment, some women contracted syphilis from men who participated in the study’s syphilitic group.

FAQ

Were men purposefully infected for the study?

No. According to a journal article about the study, published in 1936, the 399 men in the syphilitic group were initially recruited because they already had late-latent syphilis. The 201 men in the control group did not have the disease.

Why was the U.S. Public Health Service’s Untreated Syphilis Study at Tuskegee unethical?

There is no evidence that researchers obtained informed consent from participants. Also, the participants were not offered available treatments, even after penicillin became widely available.

How much money did the study participants receive from the 1974 out of court settlement?

The $10-million settlement was divided into four categories:

1. Living syphilitic group participants received $37,500.
2. Heirs of deceased syphilitic group participants received $15,000.
3. Living control group participants received $16,000.
4. Heirs of deceased control group participants received $5,0002.

This event acknowledged the 50th anniversary of the end of the United States Public Health Service Study of Untreated Syphilis in the Negro Male at Tuskegee and Macon County, Alabama, 1932 -1972. The intention was to create a space for authentic, accurate storytelling. It was also meant to encourage discussion regarding current and future opportunities for public health leaders to move from trust to trustworthiness.

The program examined what happened, how and why it happened, lessons learned, the noticeable effects still felt today, and CDC's on-going role in addressing health equity.

Participants included experts in the fields of public health, ethics, history, and journalism. In addition to our speakers, we featured moderated panel discussions. The program was a hybrid event, available both virtually and in-person.
