Should really read up on the Guatemala experiments which happened at the same time.

Beginning in 1946, the United States government immorally and unethically—and, arguably, illegally—engaged in research experiments in which more than 5000 uninformed and unconsenting Guatemalan people were intentionally infected with bacteria that cause sexually transmitted diseases. Many have been left untreated to the present day.

Graphic detail about one experiment

“It is important to emphasize the facts surrounding the Guatemala sexually transmitted disease (STD) experiments to properly evaluate the moral, ethical, and legal implications of the experiments. The experiments were not conducted in a sterile clinical setting in which bacteria that cause STDs were administered in the form of a pin prick vaccination or a pill taken orally. The researchers systematically and repeatedly violated profoundly vulnerable individuals, some in the saddest and most despairing states, and grievously aggravated their suffering. For example:

Berta was a female patient in the psychiatric hospital. Her age and the illness that brought her to the hospital are unknown. In February 1948, Berta was injected in her left arm with syphilis. A month later, she developed scabies (an itchy skin infection caused by a mite). Several weeks later, [lead investigator Dr. John] Cutler noted that she had also developed red bumps where he had injected her arm, lesions on her arms and legs, and her skin was beginning to waste away from her body. Berta was not treated for syphilis until three months after her injection. Soon after, on August 23, Dr. Cutler wrote that Berta appeared as if she was going to die, but he did not specify why. That same day he put gonorrheal pus from another male subject into both of Berta’s eyes, as well as in her urethra and rectum. He also re-infected her with syphilis. Several days later, Berta’s eyes were filled with pus from the gonorrhea, and she was bleeding from her urethra. On August 27, Berta died.”
