Issued in 1974, 45 CFR 46 raised to regulatory status what?
Issued in 1974, 45 CFR 46 raised to regulatory status the U.S. Public Health Service policy of 1966 titled "Clinical Research and Investigation Involving Human Beings." What had been an internal PHS policy became binding federal regulation for HHS-funded human-subjects research.
The answer
When 45 CFR 46 was first issued in 1974, it took the existing U.S. Public Health Service (PHS) policy of 1966 — titled "Clinical Research and Investigation Involving Human Beings" — and elevated it from an internal agency guideline to enforceable federal regulation. In plain terms, a policy that agencies were merely expected to follow became law that federally funded research must follow. The 1974 codification happened in the same year Congress passed the National Research Act, which created the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. That is the tandem you need to remember: the National Research Act was the statute, and 45 CFR 46 was the regulation that gave the earlier PHS policy the force of law.
The practical effects were concrete. 45 CFR 46 required that institutions conducting Department of Health, Education, and Welfare (now HHS) research establish Institutional Review Boards (IRBs) to review studies in advance, and it required documented informed consent from participants. These two mechanisms — prior independent review and voluntary informed consent — are the operational heart of the regulation.
Why the framing matters
Students often confuse what 45 CFR 46 did in 1974 with what came later. 45 CFR 46 did not itself issue the ethical principles of respect for persons, beneficence, and justice — those came in 1979 with the Belmont Report, written by the very commission the National Research Act created. Nor was 45 CFR 46 the same thing as the Common Rule: the Common Rule is the 1991 harmonized version of Subpart A of 45 CFR 46 that many federal agencies adopted together. So the correct 1974 statement is narrow and specific — it regulatory-ized the 1966 PHS policy, nothing grander.
It is also wrong to say 45 CFR 46 "created" the Nuremberg Code or the Declaration of Helsinki. The Nuremberg Code (1947) came out of the post-World War II Doctors' Trial, and the Declaration of Helsinki (1964) was issued by the World Medical Association. Both are international ethics documents that influenced U.S. policy but are not U.S. regulations.
The bigger picture
The timeline is the study aid the login-walled answer dumps never give you. Nuremberg Code (1947) established voluntary consent as a principle. The Declaration of Helsinki (1964) extended it. The PHS issued its human-subjects policy in 1966. The Tuskegee Syphilis Study, exposed publicly in 1972, created the political pressure that produced the National Research Act of 1974 — and, alongside it, 45 CFR 46. The Belmont Report followed in 1979, and the Common Rule in 1991. Seeing 45 CFR 46 as the 1974 hinge between the Tuskegee scandal and the Belmont principles is what makes the CITI answer stick.

Frequently asked
What is 45 CFR 46 also known as?
45 CFR 46 is the federal regulation for the protection of human subjects, and its Subpart A is commonly known as the 'Common Rule' after it was harmonized across agencies in 1991. It is administered by the HHS Office for Human Research Protections (OHRP).
What did the 1974 National Research Act establish?
The 1974 National Research Act created the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. That commission later authored the 1979 Belmont Report. The Act also prompted codifying human-subjects protections as 45 CFR 46.
What is the difference between 45 CFR 46 and the Belmont Report?
45 CFR 46 is enforceable federal regulation with specific requirements like IRB review and informed consent. The Belmont Report (1979) is a foundational ethics document stating three guiding principles — respect for persons, beneficence, and justice — but is not itself law.
When was the Common Rule created?
The Common Rule was created in 1991, when Subpart A of 45 CFR 46 was adopted in a harmonized form by numerous federal departments and agencies so that a single baseline standard would govern federally funded human-subjects research.
