NEW! Announcing Public Consultation on a Draft Revised Version of the Declaration of Helsinki
Open Now: Phase 2 Public Comment Period (3 June – 24 June)

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.

At the WMA Council meeting in April 2022, a workgroup was established to begin another revision of this important document. The American Medical Association (AMA) is leading this process.

The revision process is designed to be collaborative, transparent, and inclusive. The workgroup’s efforts are informed by regional and topical meetings spread over two years, where issues are discussed by local and international experts and engaged audiences with diverse opinions.  Resulting edits to the principles proposed by the workgroup are ultimately circulated worldwide for public comment periods for feedback.

The regional expert meetings are the following:

In order to maximize input by all stakeholders and the public, we are providing two separate public comment periods. A phase 1 public comment period was held in February 2024 to address issues from the first few regional meetings, and a phase 2 comment period is open from 3 to 24 June 2024, to cover additional topics that have been addressed.

Consideration for Adoption: General Assembly Meeting Helsinki, Finland

The workgroup intends to recommend a final updated draft of the Declaration of Helsinki to the Medical Ethics Committee of the World Medical Association, and the document is intended to be considered by the Council and the General Assembly in Helsinki, Finland in October 2024.
