About this episode
If Covid-19 spreads across Africa, it could be a catastrophe. Its health systems are already under strain and could buckle under more pressure. Lockdowns have badly affected local economies and pushed millions into poverty. Ngozi Okonjo-Iweala is the chair of GAVI, Global Alliance for Vaccines and Immunization. She's also a Covid-19 envoy for the African Union. As the world races to find a vaccine, how will she ensure lower income countries don't get forgotten? (Photo: Ngozi Okonjo-Iweala. Credit: AFP)
