Polio is still a critical problem in Pakistan where vaccination efforts have stalled. Khalida Nasreen is on a mission to change that. Every morning at 5 a.m., she hops on a motorbike and makes her way around Karachi, going door-to-door to inoculate the children in town. It’s a dangerous job as healthcare workers have lost their lives in the same pursuit, but that doesn’t stop Khalida. Thanks to her efforts, the prevalence of polio in town has decreased, building a brighter future for the next generation of Pakistani children.
