Political engagement: a key pillar in revitalisation of polio and routine immunisation programmes in the Democratic Republic of the Congo.

Immunisation is a high priority for improving health outcomes. Yet, in many low-income and middle-income countries, achieving coverage targets independently is hindered by lack of domestic resources and reliance on partners' support. Both the 2001 Abuja Declaration and 2016 Addis Declaration were key political commitments to improving immunisation coverage; however, many signatories have yet to meet international targets.
