The WHO Pandemic Preparedness Treaty

In March 2021, a group of world leaders, including then UK Prime Minister Boris Johnson, announced an initiative for a new treaty on pandemic preparedness and response. This initiative was taken to the World Health Organization (WHO) and has been negotiated, drafted, and debated by a newly-established Intergovernmental Negotiation Body.

This briefing provides an overview of the key background, progress, and developments of the treaty as of 29 May 2024. It will also give an overview of the parallel amendments being made to the International Health Regulations.

In May 2024, negotiations on the Pandemic Treaty had failed to reach a conclusion before the 2024 World Health Assembly.  However, the proposed treaty was further negotiated and finalised to present to the 78th World Health Assembly in May 2025. and formally adopted by the Assembly on 20 May 2025.

The Pandemic Agreement will not open for signature until the adoption of an Annex, described in Article 12 of the Agreement, on a Pathogen Access and Benefit-Sharing system. Work on the adoption of the Annex will be considered at the 79th World Health Assembly.

The Agreement will enter into force after 60 ratifications.

The 78th World Health Assembly runs from 19 May to 27 May 2025.

What is being proposed?

In the March 2021 joint article, the group of leaders said:

The main goal of this treaty would be to foster an all of government and all of society approach, strengthening national, regional and global capacities and resilience to future pandemics. This includes greatly enhancing international co-operation to improve, for example, alert systems, data-sharing, research and local, regional and global production and distribution of medical and public health counter-measures such as vaccines, medicines, diagnostics and personal protective equipment.

The article acknowledges existing provision for a coordinated international response under the International Health Regulations, which would “underpin such a treaty”.

In October 2021, the Working Group on Strengthening WHO Preparedness for and Response to Health Emergencies (WGPR) published a ‘zero draft’ report outlining an assessment of the benefits of a new WHO convention, agreement or other international instrument on pandemic preparedness and response, for consideration by the World Health Assembly. This Report, among other things, suggested that such an initiative “could include promoting high-level political commitment and whole-of-government whole-of-society approaches, addressing equity, enhancing the One Health approach, and strengthening health systems and their resilience.”

In this session, the WHA agreed to establish an Intergovernmental Negotiating Body to draft and negotiate “a WHO convention, agreement, or other international instrument on pandemic prevention, preparedness and response.”

Does the UK support the treaty?

Then Prime Minister Boris Johnson was a signatory to the article proposing the treaty initially

In 2022, the Conservative Government stated that it supported a new legally-binding instrument “as part of a cooperative and comprehensive approach to pandemic prevention, preparedness and response.” However, in May 2024 the then government indicated that it would not sign the treaty in its current form. It did not explicitly state the reasons for this.

The UK’s final position on the exact substance of the treaty remains to be seen as the Treaty opens for adoption, but the Government has indicated general support for such a treaty in principle.

What does the treaty say?

The Zero Draft of the treaty, known as the Zero Draft of WHO CA+, was published on 1 February 2023, and discussed at the Intergovernmental Negotiating Body’s fourth meeting in 2023.

The latest public version of the text was published following the final rounds of negotiations, in preparation for the 78th World Health Assembly in May 2025.

Because the Zero Draft was the starting point for negotiations, the substantive provisions and content of the treaty continued to change. The parties negotiated on issues such as:

  • The definition, means, and procedure for declaring a pandemic, and what this actually means in practice for states.
  • How the treaty would work alongside the International Health Regulations.
  • Key international principles that will guide the treaty, such as human rights, sovereignty, equity, solidarity, transparency, accountability and more.
  • How to achieve equity in the global supply chain for pandemic-related products, and access to relevant technologies.
  • Strengthening the resilience and responsiveness of health systems.
  • How states and the WHO should be coordinating and cooperating in pandemic preparedness and response.
  • How to finance pandemic preparedness and response initiatives.
  • Setting up a new Governing Body for the treaty – a COP or Conference of the Parties.
  • Other general legal issues relating to the treaty, such as amendments, withdrawal, and dispute settlement.

Reports suggest that the main contentious issues in negotiations were over the sharing of pandemic-related health products via donations and affordable / not-for-profit pricing for developing states, and the corresponding sharing of pathogen data, known as the Pathogen Access and Benefit Sharing System. This is contained in Article 12 of the April 2024 version of the negotiating text of the treaty, and the version submitted for consideration by the World Health Assembly.

Will the WHO be given powers to impose restrictive measures?

Neither the proposed treaty, nor the amendments to the International Health Regulations propose to cede powers of this kind or sovereignty to the WHO.

During an Urgent Question in the House of Commons on 14 May 2024, then Minister for Health and Secondary Care indicated that “under no circumstances will we allow the WHO to have the power to mandate lockdowns. That would be unthinkable and has never been proposed.”

In May 2024, a WHO spokesperson told The Guardian that:

Claims that the draft agreement will cede sovereignty to WHO and will give the WHO secretariat power to impose lockdowns or vaccine mandates on countries are false and have never been requested nor proposed. This agreement will not, and cannot, grant sovereignty to WHO.

This briefing further explains where some concerns may have originated from, and how negotiations have addressed potential confusion over some proposals.

How does the treaty relate to the International Health Regulations?

Alongside the development of the pandemic preparedness treaty, the WHO is also undertaking a review of the International Health Regulations 2005 (IHR).

As part of this process, more than 300 amendments have been proposed by States Parties.

These amendments were subject to a review by the Review Committee regarding amendments to the International Health Regulations. The terms of reference (PDF) for this Review Committee detail the exact scope of the work and analysis that the Committee was expected to undertake on the proposed amendments.

The WHO has also produced a Reference Document (PDF) containing a list of the proposed amendments alongside the Review Committee’s technical recommendations to these.
