The Final Piece of the Puzzle: WHO Extends Negotiations on Pandemic Agreement’s PABS Annex

The global community is still racing to build a more equitable shield against future health crises. While the World Health Organization (WHO) Member States have made strides toward a unified pandemic response, a critical component remains unfinished. Recently, negotiators agreed that additional time is necessary to finalize the Pathogen Access and Benefit Sharing (PABS) annex, a cornerstone of the broader WHO Pandemic Agreement.

The PABS system isn’t just a technical detail; it’s the mechanism intended to ensure that when a new threat emerges, the world doesn’t repeat the inequities seen during the COVID-19 pandemic. Without this annex, the overarching Pandemic Agreement cannot be signed or ratified, leaving a gap in global preparedness.

What Exactly is the PABS System?

At its core, the Pathogen Access and Benefit Sharing (PABS) system is designed as a fair exchange. In the event of a potential pandemic, countries are expected to share pathogens—the viruses or bacteria causing the disease—and the associated genetic data rapidly. In exchange, those countries must receive a fair and equitable share of the benefits that result from that data.

These “benefits” typically include:

• Vaccines: Ensuring low- and middle-income countries aren’t at the back of the line.
• Diagnostics: Providing the tools needed to identify the pathogen quickly.
• Therapeutics: Guaranteeing access to life-saving medications.

By putting access and benefits on “equal footing,” the WHO aims to incentivize transparency and cooperation over hoarding and nationalism.

Why the Delay in Finalization?

Negotiations recently concluded the resumed session of the sixth meeting of the Intergovernmental Working Group (IGWG) in Geneva. Despite progress, Member States found they weren’t yet ready to finalize the framework. The reason? The sheer complexity of the task.

Ambassador Tovar da Silva Nunes of Brazil, the IGWG Bureau Co-Chair, noted that finalizing a document of such “technical and legal complexity requires precision and dedication.” While the commitment remains strong, the legal language must be airtight to ensure all nations—regardless of their wealth or infrastructure—are protected.

“Real progress was made on the PABS annex and I am confident through continued negotiations differences will be overcome,” said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General. “Member States should continue approaching the outstanding issues with a sense of urgency because the next pandemic is a matter of when, not if.”

The Road Ahead: Key Dates and Deadlines

The PABS annex is the final missing piece of a larger strategy. The WHO Pandemic Agreement was originally adopted in May 2025 to strengthen how countries prevent, prepare for, and respond to pandemics. However, the PABS system is the “last piece of the puzzle” required to make the entire agreement operational.

Here is the current timeline for the remaining negotiations:

• Late May 2026: The outcome of current work will be presented to the Seventy-ninth World Health Assembly (WHA).
• WHA Decision: The Assembly will decide whether to continue the IGWG’s work as mandated in Resolution WHA78.1. This could lead to a final submission by May 2027 or earlier via a special session in 2026.
• July 6–17, 2026: The IGWG will convene for its seventh meeting to continue hammering out the details.

The Bottom Line

The struggle to finalize the PABS annex highlights the tension between national interests and global health security. However, as IGWG Co-Chair Mr. Matthew Harpur emphasized, there is a “strong and continuing commitment” to get this right. The goal is a framework that ensures the world is not just better prepared, but more equitably protected when the next pandemic arrives.

For health professionals and policymakers, the focus now shifts to the July meetings. The world can afford to be precise, but as Dr. Tedros warned, it cannot afford to be sluggish.
