In an era still echoing the devastation wrought by COVID-19, the world has taken a significant and historic step toward better global health security. At its 78th session, the World Health Assembly adopted the WHO Pandemic Agreement, signalling a new era of international collaboration to prevent and mitigate future pandemics. Emerging from three years of negotiations driven by the shortcomings exposed during the COVID-19 crisis, the treaty lays a foundation for equitable access to life-saving tools and better preparedness. However, while its intent is noble and necessary, its successful implementation will be fraught with challenges that the global community must confront head-on.
COVID-19 unmasked grave inequities in the global health system. While high-income countries secured early and ample access to vaccines and therapeutics, many low- and middle-income nations-especially across the Global South-were left behind. The delay in access not only prolonged their public health crises but also undermined global efforts to curb the pandemic. The WHO Pandemic Agreement is, at its core, a moral and strategic response to these inequities. The treaty aims to ensure the timely and equitable distribution of vaccines, diagnostics, and therapeutics during future pandemics. It recognizes that in a globally connected world, viruses respect no borders, and unequal access anywhere is a threat to public health everywhere.
One of the treaty’s most lauded aspects is its emphasis on multilateral cooperation and science-based public health responses. It reinforces the need for nations to collaborate rather than compete in times of crisis. Formalizing principles and mechanisms for information sharing, collective surveillance, and equitable distribution of health tools strengthen the global health architecture. Furthermore, the proposed Pathogen Access and Benefit Sharing (PABS) system will help ensure that genetic data from pathogens is shared rapidly and fairly and that benefits arising from such data-such as vaccines and medicines-are equitably accessible. This system addresses long-standing concerns about bio-sovereignty and ensures that nations contributing to global knowledge are not sidelined when benefits are distributed.
The agreement is also a victory for transparency and accountability. Member states will be expected to strengthen national preparedness plans, improve health system resilience, and engage in regular review and compliance mechanisms. These are essential steps toward avoiding the systemic breakdowns that characterized the early months of the COVID-19 pandemic.
Despite its strengths, the agreement is not without controversy. Its unanimous adoption was elusive-11 countries, including Russia, Iran, Italy, and Slovakia, abstained. Their reservations, including concerns about national sovereignty, centralized control by WHO, and vaccine scepticism, cannot be dismissed lightly. Any treaty that aims to centralize aspects of health governance may face political pushback, particularly in polarized or protectionist political environments. Another significant challenge lies in enforcement. International agreements are only as strong as the willingness of nations to adhere to them. Without legally binding mechanisms or meaningful consequences for non-compliance, there is a risk that the treaty becomes more aspirational than operational. Ratification by 60 countries is required for the agreement to come into force-a milestone that may take time, especially given varying political climates and domestic legislative processes.
The PABS system, while promising, also raises complex issues around intellectual property rights and commercial interests. Ensuring that pharmaceutical innovation continues while guaranteeing equitable access will require careful negotiation and a delicate balancing act. Global pharmaceutical giants may resist measures that they perceive as threats to profitability, and this could hamper progress unless strong safeguards and incentives are in place.
The adoption of the WHO Pandemic Agreement marks a hopeful and historic moment. It reflects a collective understanding that the world cannot afford to repeat the mistakes of COVID-19. The pandemic showed that no nation, however wealthy or prepared, is safe until every nation is. This agreement offers a “once-in-a-lifetime opportunity” to transform global health preparedness. But the road ahead will require political courage, international solidarity, and relentless advocacy to turn words into action. The promise is real; so too are the perils of inaction.
