👉 One notable example of implemented human experimentation is the Tuskegee Syphilis Study, where African-American men with syphilis were misled and denied treatment for decades to study the disease's progression, while another instance involves modern clinical trials testing new drugs or treatments on participants without obtaining fully informed consent, such as in some COVID-19 vaccine trials. These experiments highlight the ethical issues surrounding human experimentation and the importance of rigorous oversight and ethical considerations.
