The vaccines are finally here, and countries around the world are running a race against time to get them into our arms as fast as possible. At the moment, Israel is leading the way, and the UK is currently forth in the world for vaccine doses administered. But, if the aim in Britain is to get 15 million people their first jab by mid February, we’re going to have to get more vaccines quickly. And that’s no mean feat because making vaccines is a complicated business, and delivering them isn’t easy either, even when you have the storks of Yeovil on your side. Tim Harford explains why on this edition of How To Vaccinate The World. Producers: Sandra Kanthal and Josephine Casserly
