Transition IMB

Polio Transition Independent Monitoring Board (TIMB)

This page and its sub-pages are maintained by the Transition Independent Monitoring Board and reflect the views of that body alone.


As we near the end of the polio eradication initiative, there is a need to plan for the ramp-down and closure of the GPEI. During nearly three decades of operations, the GPEI has mobilized and trained millions of volunteers, social mobilizers, and health workers; accessed households untouched by other health initiatives; mapped and brought health interventions to chronically neglected communities and areas of conflict; and established a standardized, real-time global surveillance and response capacity, and a global laboratory network of accredited labs and personnel.

Polio transition planning aims to:

  • Ensure that functions needed to maintain a polio-free world after eradication are mainstreamed into ongoing public health programs
  • Ensure that the knowledge generated and lessons learned from polio eradication activities are documented and shared with other health initiatives
  • Support, where feasible, desirable and appropriate, transition capabilities and processes to assist other health priorities and ensure sustainability of the experience of the GPEI program.

Terms of reference

The Polio Transition IMB (TIMB) shall independently monitor and guide the process of transition planning, assessing the quality, sufficiency and impact of work being undertaken to achieve transition planning aims stated in the Polio Eradication and Endgame Strategic Plan 2013-18.

The Polio Transition IMB is established at the request of the Polio Oversight Board [1].

The  TIMB meets every six months. The next meeting will be held 2-3 November 2017, in London, UK.
