In this TEDx talk in Johannesburg, novelist and medical doctor Kopano Matlwa Mabaso tells how she and her friend Chrystelle Wedi sought to turn the tide of preventable deaths in women at childbirth. Their idea made them winners of the first Aspen Ideas Award. Their idea was to set up mobile, ultrasound scan clinics in remote and rural parts of Africa and make lifesaving antenatal healthcare more easily accessible to pregnant women. But the deepest parts of Africa are tough places to do work. Matlwa, with humility, tells how even good ideas sometimes need self-correction during implementation.
