The draft treaty focused on closing the vaccine gap between the west and developing countries, and a "Pathogen Access and Benefit-Sharing System," whereby countries would give the WHO samples and genetic sequences of potentially dangerous pathogens. In return, the WHO would contract vaccine manufacturers and provide participating nations with 20% of the vaccines they need.

Members disagreed on the fairness and cost of implementing the treaty.

The World Health Assembly (WHA) now must try to find a path forward at its annual meeting in Geneva on Monday.
