How do the COVID vaccines work? How do we prioritise recipients? What are the major decisions facing policymakers when executing a mass vaccination campaign -- and where can science help to advise them?
George Griffin discusses these questions with Toby Wardman of SAPEA. We also discuss how to get jabs to developing countries, the origins of the anti-vax movement, and whether we should be worried about rare blood clots.
