- Declaration of Helsinki (1964)
- Adopted by the World Medical Association as a set of ethical guidelines for medical research involving human subjects
- Emphasizes the primacy of the individual's well-being over the interests of science and society, requiring a careful assessment of risks and benefits
- Tuskegee Syphilis Study (1932-1972)
- Unethical study conducted by the U.S. Public Health Service on African American men with syphilis, who were not informed of their diagnosis and were denied effective treatment (penicillin)
- Revelations about the study led to increased public awareness of research ethics and the need for oversight, contributing to the development of modern bioethical principles and regulations
- (1979)
- Produced by the U.S. National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research in response to the Tuskegee Syphilis Study
- Identifies three fundamental ethical principles for human subject research: respect for persons (autonomy), beneficence (maximizing benefits and minimizing risks), and justice (fair distribution of risks and benefits)
- Serves as the foundation for current U.S. regulations on human subject research, including the Common Rule (45 CFR 46)
Organizations in bioethical oversight
- Professional organizations
- American Medical Association (AMA) develops and maintains the Code of Medical Ethics, providing guidance on ethical issues in medical practice, such as patient-physician relationships and end-of-life care
- Biotechnology Innovation Organization (BIO) represents the biotechnology industry and promotes responsible and ethical practices in biotechnology research and development, including intellectual property protection and public engagement

Key Terms to Review (8)
Belmont Report: The Belmont Report is a foundational document in the field of bioethics that outlines ethical principles and guidelines for research involving human subjects. It emphasizes three core principles: respect for persons, beneficence, and justice, which serve as a framework for conducting ethical research and protecting participants' rights. This report significantly influenced the development of policies and regulations governing human subjects research and has become integral to understanding the historical context of bioethics and research ethics committees.
Helsinki Declaration: The Helsinki Declaration is a set of ethical principles developed by the World Medical Association (WMA) to guide medical research involving human subjects. Established in 1964 in Helsinki, Finland, it emphasizes the importance of informed consent, the welfare of research participants, and the need for rigorous ethical review processes. The declaration has been revised multiple times to adapt to advancements in medical research and changing societal values.
Henry K. Beecher: Henry K. Beecher was a prominent American anesthesiologist and a key figure in the development of medical ethics, particularly known for his advocacy of informed consent and ethical research practices. His work highlighted the importance of protecting human subjects in medical research, especially in the wake of unethical practices that were common in the mid-20th century. Beecher's influence extends to shaping bioethical discussions surrounding clinical trials and somatic gene therapy, making him a foundational figure in these areas.
Informed Consent: Informed consent is the process by which individuals voluntarily agree to participate in research or medical procedures after being fully informed of the risks, benefits, and alternatives involved. This essential ethical principle ensures that participants have the autonomy to make decisions based on an understanding of what they are agreeing to, emphasizing respect for their rights and well-being.
Nuremberg Code: The Nuremberg Code is a set of ethical principles established for human experimentation, formulated in 1947 during the Nuremberg Trials in response to the atrocities committed by Nazi physicians. It emphasizes the necessity of voluntary consent, the importance of minimizing risks to participants, and the obligation to ensure scientifically valid research. This code laid the groundwork for modern bioethics, influencing regulations and guidelines surrounding clinical trials, medical research, and ethical standards in healthcare.
Peter Singer: Peter Singer is a prominent Australian moral philosopher known for his work in bioethics and utilitarianism, particularly concerning the ethical implications of biotechnology.
