WHO Pandemic Agreement: Pathogen Sharing Talks Extended to May Deadline

Geneva – Global efforts to bolster pandemic preparedness took a significant, though cautious, step forward this week as World Health Organization (WHO) Member States agreed to extend negotiations surrounding a crucial annex to the landmark WHO Pandemic Agreement. The focus: the Pathogen Access and Benefit Sharing (PABS) system, a complex framework designed to ensure equitable access to life-saving medical countermeasures – vaccines, diagnostics, and therapeutics – in the face of future outbreaks. This extension, decided upon after intensive discussions from March 27th to April 1st, underscores the commitment to finalizing a legally binding agreement that addresses the shortcomings exposed by the COVID-19 pandemic.

The need for such an agreement stems directly from the inequities witnessed during the recent pandemic. While scientific breakthroughs delivered effective tools to combat COVID-19, their distribution was far from uniform, leaving many nations vulnerable and exacerbating existing health disparities. The WHO Pandemic Agreement, adopted by the World Health Assembly in May 2025, represents a pivotal attempt to rectify this imbalance and build a more resilient global health architecture. The PABS system, however, remains a sticking point, requiring careful negotiation to ensure both rapid access to pathogens with pandemic potential and a fair sharing of the benefits derived from their use.

Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, emphasized the importance of trust and collaboration in achieving this goal. “The Pathogen Access and Benefit Sharing system lies at the heart of the WHO Pandemic Agreement and I thank WHO Member States for their commitment to work to bring it to life,” he stated. “I urge all delegations to believe in the power of trust – trust in one another, in our institutions, and in our shared ability to transcend differences for the common public good, for solidarity and for equity.” This sentiment reflects the broader understanding that a truly effective pandemic response requires a unified, multilateral approach, moving beyond national interests to prioritize global health security.

The Core of the Debate: Pathogen Access and Benefit Sharing

The PABS system is arguably the most ambitious and potentially contentious element of the WHO Pandemic Agreement. It aims to establish a mechanism for the rapid sharing of biological samples – pathogens – that could trigger future pandemics. Currently, access to these samples is often restricted, hindering research and delaying the development of crucial medical countermeasures. However, simply sharing pathogens isn’t enough. The “benefit sharing” component is equally critical, ensuring that the countries and communities that contribute these samples also benefit from any resulting innovations, such as vaccines or treatments. What we have is particularly important for low- and middle-income countries, which often bear the brunt of pandemic impacts but lack the resources to invest in research and development.

Negotiations have centered on defining precisely how these benefits should be distributed. Discussions have covered a range of complex issues, including the nature of contractual arrangements governing the PABS system, and the governance structures needed to ensure transparency and accountability. According to Ambassador Tovar da Silva Nunes, of Brazil, and co-chair of the Intergovernmental Working Group (IGWG) on the WHO Pandemic Agreement, negotiators are “working intensively towards having an ambitious and equitable Pathogen Access and Benefits Sharing annex ready for adoption at the World Health Assembly in May.”

A History of Global Health Security Efforts

The current push for a pandemic treaty builds upon decades of efforts to strengthen global health security. Following the SARS outbreak in 2003, the International Health Regulations (IHR) were revised in 2005 to improve the detection and reporting of public health emergencies. The WHO notes that the COVID-19 pandemic highlighted significant gaps in the IHR, particularly in areas such as early warning, data sharing, and equitable access to medical countermeasures. The Pandemic Agreement is intended to address these shortcomings and create a more robust and coordinated global response system.

The process leading to the agreement began in 2021, with a three-year negotiation process involving governments and stakeholders. The aim was to create a legally binding international instrument that would make the world safer and more equitable in the face of future pandemics. The adoption of the agreement in May 2025 was a landmark achievement, but the work is far from over. The PABS annex represents a critical final piece of the puzzle, and its successful negotiation is essential to realizing the full potential of the agreement.

Challenges and Concerns Remain

While the extension of negotiations signals a continued commitment to the PABS system, significant challenges remain. One key concern revolves around intellectual property rights. Some countries and pharmaceutical companies are hesitant to share intellectual property, fearing that it could stifle innovation. However, proponents of the PABS system argue that equitable access to technology is essential for ensuring a rapid and effective pandemic response. Finding a balance between incentivizing innovation and promoting access will be crucial.

Another challenge lies in establishing effective governance mechanisms. The PABS system must be transparent, accountable, and free from political interference. This requires establishing clear rules and procedures for sharing pathogens and distributing benefits, as well as independent oversight to ensure compliance. Mr. Matthew Harpur, of the United Kingdom of Great Britain and Northern Ireland, and also a co-chair of the IGWG, acknowledged the ongoing work, stating, “With less than two months until the World Health Assembly in May, I welcome the commitment shown this week by Member States towards finding consensus on outstanding areas in the Pathogen Access and Benefit Sharing system.”

What Happens Next?

The negotiations will resume from April 27th to May 1st, with informal discussions taking place beforehand. The goal is to finalize the PABS annex in time for consideration by the World Health Assembly in May. Once the annex is adopted, the full Pandemic Agreement will be open for signature and ratification by WHO Member States. The agreement will officially enter into force 30 days after 60 countries have ratified it. This timeline underscores the urgency of the situation, as the world remains vulnerable to new and emerging infectious diseases.

The successful implementation of the WHO Pandemic Agreement, and particularly the PABS system, will require sustained political will, financial investment, and international cooperation. It is a complex undertaking, but one that is essential for protecting global health security and preventing a repeat of the devastating consequences of the COVID-19 pandemic. The stakes are high, and the world is watching closely.

The next crucial step is the World Health Assembly in May, where Member States will aim to adopt the final PABS annex.
