Supporters say the accord marks a major One Health breakthrough because it directly links human health to animal health and the environment while trying to correct the inequities in vaccines, tests and treatments that defined much of the COVID-19 response.
A Reuters report on the vote said 124 countries voted in favor, 11 abstained and none opposed the agreement after Slovakia forced a ballot. That margin gave the pact broad political weight even if it stopped short of unanimity.
In its official adoption announcement, WHO said the agreement is designed to strengthen international coordination on pandemic prevention, preparedness and response, improve equitable access to vaccines, therapeutics and diagnostics, and make clear that the organization cannot use the pact to impose domestic measures such as lockdowns or vaccine mandates. WHO also described it as only the second international legal agreement negotiated under Article 19 of its constitution, after the tobacco control convention.
Why the WHO Pandemic Agreement matters for One Health
The final agreement text makes the One Health principle explicit in Article 5, calling on parties to promote an approach that recognizes the links among human health, animal health and the environment and to address risks at the human-animal-environment interface.
That is a meaningful shift in emphasis. Instead of treating pandemics only as emergency-response failures, the agreement pushes countries to look earlier at the conditions that allow outbreaks to emerge, spill over and accelerate.
A WHO overview of the pact says the framework also covers disease surveillance, stronger health systems, workforce protection, local production capacity, financing and supply-chain coordination. Once the annex is adopted, WHO says the agreement will open for signature and will enter into force 30 days after 60 countries ratify it.
The road to the WHO Pandemic Agreement
The deal did not appear overnight. WHO members first opened the negotiating process in December 2021, then spent years arguing over equity, sovereignty, technology transfer and how benefits from pathogen sharing should be distributed.
By May 2024, talks had missed their original deadline, underscoring how hard it was to reconcile the demands of wealthier states, developing countries and pharmaceutical interests. Negotiators only landed a draft agreement in April 2025, weeks before the assembly vote.
That long runway helps explain why backers see the pact as more than symbolism. COVID-19 exposed how quickly national stockpiling and unequal access can overwhelm global solidarity, and the agreement tries to move those lessons into standing rules and institutions.
What comes next for the WHO Pandemic Agreement
The political breakthrough is real, but the legal and operational work is not finished. WHO said in March 2026 that member states had to extend negotiations on the key Pathogen Access and Benefit-Sharing annex, a core component that must be completed before the full agreement can open for signature and ratification.
If countries can close that gap, the WHO Pandemic Agreement may be remembered as the moment governments tried to hardwire One Health, equity and earlier prevention into the global system instead of improvising after the next outbreak is already spreading.
