Tóm tắt	The Declaration of Helsinki (1964) is the foundational international ethical code for medical research involving human subjects, established by the World Medical Association. It extended earlier principles (Nuremberg Code 1947) to include therapeutic research and formalized the physician's ethical duty to prioritize subject welfare. Updated nine times through 2013, it remains the standard adopted by major medical journals, research ethics committees, and regulatory bodies worldwide.	Informed consent is the cornerstone of ethical human subjects research, requiring researchers to disclose material information about a study and obtain voluntary agreement from subjects before participation. Established as the first principle of the Nuremberg Code (1947) and formalized in subsequent ethical frameworks (Declaration of Helsinki 1964, Belmont Report 1979), informed consent protects subject autonomy, enables risk-benefit assessment, and creates accountability. Effective informed consent requires far more than obtaining a signature—it demands clear communication, genuine comprehension, and authentic voluntariness.
