In Djibouti’s arid north, reaching every child with life-saving vaccines is no simple task. The remote village of Gadid, tucked into the rocky foothills of the Obock region, lies far beyond paved roads or regular health services. Here, the nearest clinic may be a full day’s journey away—and many children grow up without ever being seen by the formal health system.

But during the April 2025 national polio campaign, a mobile vaccination team set out to change that reality. Their goal was not only to deliver oral polio drops, but to identify and reach the most vulnerable children, especially those missed by routine immunization. The team traveled by foot, climbing steep, winding trails under the relentless sun—driven by a simple but powerful commitment: no child should be left behind.
