Africa's vaccine gap - a podcast by BBC World Service

The G7 group of the world's leading economies held a virtual meeting today to discuss the distribution of vaccines to Africa. We hear from Dr Mohga Kamal-Yanni, a global health expert with the People’s Vaccine Alliance. Vaccines aren't the only challenge in confronting coronavirus in Africa; many of the region's countries still don't have the ventilators needed to keep the most seriously ill patients alive. But now a Nigerian man has come up with a ventilator that's powered by water and is cheap to make; we talk to the ventilator's inventor, Yusuf Bilesanmi. Plus, the UK Supreme Court has ruled that the ride-hailing app Uber must classify its drivers as workers and not as self-employed; Susannah Streeter of Hargreaves Lansdown goes over the implications. And as President Biden takes the US back into the Paris Climate Agreement process, the BBC's Mike Johnson looks at the future of the US energy sector. (Picture of vaccine via Getty Images).
