Pandemic Preparedness Needs Clear Rules

Medically reviewed | Published: | Evidence level: 1A
Public health leaders are urging countries to complete the Pathogen Access and Benefit Sharing annex to the WHO Pandemic Agreement. The unfinished framework is intended to connect timely sharing of pathogen materials and sequence information with more predictable access to resulting vaccines, diagnostics and treatments.

What Is the Pathogen Access and Benefit Sharing Annex?

Quick answer: It is a proposed framework for sharing pandemic-relevant pathogen materials and sequence information while linking that access to public health benefits.

Laboratories need access to representative pathogen samples and genetic sequence information to characterize emerging threats, assess diagnostic tests and begin developing vaccines or medicines. The proposed Pathogen Access and Benefit Sharing framework, commonly called PABS, is intended to establish agreed procedures for that cooperation under the WHO Pandemic Agreement.

The benefit-sharing component is equally important. Countries providing biological materials or sequence information want confidence that the products developed from those resources will not remain inaccessible during an emergency. Negotiators must therefore address scientific access, legal certainty and the availability of vaccines, diagnostics and treatments without creating delays that impede urgent research.

Why Does Faster Pathogen Sharing Matter During a Pandemic?

Quick answer: Early access to reliable samples and sequence data helps scientists identify threats and begin evaluating medical countermeasures sooner.

Genomic information can help researchers track pathogen evolution, detect potentially important mutations and design laboratory assays. Physical samples remain necessary for many activities, including validating diagnostic performance, studying how a pathogen behaves and testing whether antibodies or candidate medicines can neutralize it.

Speed alone is not sufficient. Shared information must be accurate, accompanied by useful clinical and epidemiological context, and handled through systems that support biosafety, biosecurity and responsible research. Sustainable laboratory capacity across regions also matters because global surveillance is stronger when more countries can collect, characterize and securely share high-quality evidence.

How Could the Annex Affect Access to Vaccines and Treatments?

Quick answer: A well-designed annex could make access commitments more predictable before the next international health emergency begins.

During a rapidly expanding outbreak, demand for vaccines, tests and treatments may exceed initial manufacturing capacity. Negotiating access only after scarcity develops can slow distribution and weaken trust. The PABS discussions seek to establish expectations in advance for how participating manufacturers and institutions would share public health benefits.

Final rules must remain practical for laboratories, public health agencies and product developers. Clear definitions, transparent obligations and workable compliance mechanisms could encourage participation, while excessive administrative complexity could delay research. The public health value of the annex will ultimately depend on whether it improves both the speed of scientific cooperation and access to effective, quality-assured medical products.

Frequently Asked Questions

Yes. The World Health Assembly adopted the WHO Pandemic Agreement in May 2025. Work on the Pathogen Access and Benefit Sharing annex continued separately, and the agreement's implementation depends on further international and national legal steps.

No. Biological materials must be collected, transported, stored and studied under appropriate biosafety, biosecurity, ethical and legal safeguards. Rapid cooperation and responsible laboratory practice are complementary requirements.

No framework can eliminate manufacturing constraints by itself. Clear advance commitments could, however, improve predictability and provide a stronger basis for allocating vaccines, diagnostics and treatments during a pandemic.
