The Tuskegee syphilis study
https://en.wikipedia.org/wiki/Tuskegee_syphilis_experiment
The Tuskegee Study of Untreated Syphilis in the African American Male was a clinical study conducted between 1932 and 1972 by the United States Public Health Service...…(who) started the study in 1932 in collaboration with Tuskegee University (then the Tuskegee Institute), a historically black college in Alabama. Investigators enrolled in the study a total of 600 impoverished, African-American sharecroppers from Macon County, Alabama.
Of these men, 399 had latent syphilis, with a control group of 201 men who were not infected.
As an incentive for participation in the study, the men were promised free medical care, but were deceived by the PHS, who disguised placebos, ineffective methods, and diagnostic procedures as treatment.
The men who had syphilis were never informed of their diagnosis, despite the risk of infecting others, and the fact that the disease could lead to blindness, deafness, mental illness, heart disease, bone deterioration, collapse of the central nervous system, and death…
… The men were initially told that the study was only going to last six months, but it was extended to 40 years…
… None of the infected men were treated with penicillin despite the fact that by 1947, the antibiotic had become the standard treatment for syphilis…
… The study continued, under numerous Public Health Service supervisors, until 1972, when a leak to the press resulted in its termination on November 16 of that year. The victims of the study, all African-American, included numerous men who died of syphilis, 40 wives who contracted the disease and 19 children born with congenital syphilis…
The study was ended in 1972 due to a whistle blower. I bring it up now, as it shows that the U.S. Federal Government and part of their medical community, obviously did not consider poor black lives to matter very much. As the poor black Americans were just naïve Federal Public Health Service Lab rats for 40 years of their syphilis infected lives.
It only took another 25 years for a POTUS to apologize for the atrocity.
And who remembers?
