2025 put health systems under enormous pressure, from conflict and climate shocks to rising debt and unprecedented cuts to development assistance. Yet amid that historic uncertainty, countries continued to expand protection against preventable disease, reach more children and invest more of their own resources in immunisation.

Scroll down through eight numbers that help tell the story of 2025, and read more about what sustained investment in vaccines has made possible on VaccinesWork: bit.ly/4jJbqrh
