Crucial Week of Talks at WHO as Vaccine Access, Data Sharing Divide Nations

A round of negotiations has opened this week at the World Health Organization (WHO) to resolve disputes over vaccine access and pathogen sharing under a global pandemic treaty. Although a treaty was adopted in May 2025, key issues remain unresolved, including the proposed PABS system to regulate the exchange of biological samples and genetic data. Developing countries express concerns about fair access to vaccines, while wealthier nations question the financial incentives needed to support such a system.
