As part of the #KickOutPolio campaign, young advocates from across Africa have issued an open letter urging African leaders to sustain political commitment and investment in immunization, strengthen health systems and disease surveillance, and ensure that every child is reached with life-saving vaccines.

Nigeria’s National Polio Laboratory in Maiduguri has achieved WHO accreditation for Sanger sequencing of polioviruses, marking an important milestone for polio eradication efforts. The accreditation strengthens regional capacity to rapidly detect, characterize and track polioviruses, supporting faster outbreak detection and response while enhancing surveillance capabilities across the African Region.
