The Declaration of Helsinki established ethical principles for research involving human subjects after which historical event?

• A. The Nuremberg trials
• B. The Nuremberg Code
• C. The Tuskegee study
• D. The Belmont Report

Answer: (A)

The main idea being tested is how ethical guidelines for human research were shaped by postwar revelations about abuses. The Declaration of Helsinki, adopted in 1964, grew out of concerns highlighted by the Nuremberg trials, which exposed horrific medical experiments on prisoners. Those trials led to the Nuremberg Code, establishing fundamental protections like voluntary informed consent. The Helsinki Declaration then expanded and refined those principles for medical research involving human subjects on a global scale. So the historical event that set the stage for its establishment is the Nuremberg trials.
