Abortion is technically legal in Zambia, but the reality is far more complicated. This study describes the process and results of galvanizing access to medical abortion where abortion has been legal for many years, but provision severely limited. It highlights the challenges and successes of scaling up abortion care using implementation science to document two years of implementation. The findings provide a case study of  medical abortion introduction in Zambia and offer important lessons for expanding safe and legal abortion access in similar settings across Africa.
