Global Polio Eradication Initiative (1988-present)
The initiative launched in 1988 targeting polio elimination by 2000. Cases fell by 99%, but transmission persisted for decades in conflict-affected countries — Afghanistan, Pakistan, Nigeria — and areas with vaccine refusal.
Polio was confined to a handful of countries by the mid-2000s, but eradication kept slipping.
Reaching the final unreached children proved far harder than the initial gains.
Today's zero-dose children sit in the same places polio's last cases did — conflict zones and communities with weak health systems.
