This week we’re talking to researchers about how COVID-19 vaccines are manufactured – and a battle over the intellectual property rights surrounding them. And we hear from a researcher looking into why China is closing down coal-fired power stations faster in some places than others. Welcome to episode 3 of a new podcast from The Conversation, the world explained by experts.

While some of the world’s richest countries are racing ahead with large-scale programmes to vaccinate their populations, for much of the developing world, the first doses of the vaccines remain a long way off. For the past few months, a group of countries has been pushing for the intellectual property rules around coronavirus vaccines to be temporarily waived temporarily, arguing this would help expand supply and push down costs. Ronald Labonté, Distinguished Research Chair in Globalization and Health Equity at the School of Epidemiology and Public Health at the University of Ottawa, talks us through the detail. Meanwhile, Mosoka Fallah, Lecturer at the School of Public Health, College of Health Sciences at the University of Liberia tells us what the vaccine situation is like on the ground in West Africa, and Anne Moore, Senior Lecturer in Biochemistry and Cell Biology, at University College Cork in Ireland, explains some of the processes behind making coronavirus vaccines.

In our second story, we talk to Hao Tan, Associate Professor at the University of Newcastle in Australia, on his new research on why – and where – China is decommissioning coal-fired power stations. He explains what this shift means for the wider region, and those countries which export coal to China.

And Clea Chakraverty, politics and society editor at The Conversation in France, gives us some recommended reading on a historic child sex abuse scandal shaking France.
