The 40-year Tuskegee Syphilis Study had devastating impacts on the African American community and revealed systemic ethical issues. Researchers intentionally did not treat Black men infected with syphilis, despite having penicillin, resulting in deaths and congenital syphilis cases. This vast experiment without consent eroded trust in medicine among minorities. It led to reforms like required informed consent and institutional review boards to protect human subjects. However, its harmful legacy of distrust persists today.
