Declaration of Helsinki

Medical Research Involving Human Subjects


The Declaration of Helsinki (DoH) is the World Medical Association’s (WMA) best-known policy statement. The first version was adopted in 1964 and has been amended seven times since, most recently at the General Assembly in October 2013. The current (2013) version is the only official one; all previous versions have been replaced and should not be used or cited except for historical purposes. The WMA would like to thank all those who submitted comments and suggestions for the most recent revision of the DoH.

In 2014, the WMA produced a celebratory publication to mark the 50th anniversary of the adoption of the Declaration of Helsinki. “The World Medical Association Declaration of Helsinki: 1964-2014 50 Years of Evolution of Medical Research Ethics” can be ordered online here.

Since 2016, the Declaration of Taipei on Ethical Considerations regarding Health Databases and Biobanks has complemented the Declaration of Helsinki.
