Countries revise polio emergency plans to intensify vaccination in underimmunized childrenHow are countries changing their fight to end polio for good?

Polio is a disease the world has been trying to erase for decades. While it's been eliminated in most places, it stubbornly persists in a few countries. The latest update shows health officials aren't giving up—they're changing their game plan. In nations where polio is still endemic, leaders have gone back to the drawing board. They've revised their emergency action plans, promising to innovate and intensify how they get vaccines to children, especially in underimmunized populations where the virus finds a foothold. This pivot signals a recognition that the old approaches weren't finishing the job in these last strongholds. The work is focused on reaching every child. It's important to understand what this report is and isn't telling us. It describes a change in strategy and intention, but it doesn't share any results. We don't know yet how these new, more intense vaccination drives are working, or if they're leading to fewer cases. The story here is about a renewed commitment in the fight's final chapters, but the final outcome is still being written.
