BBC World Service - More or Less, Wales Vaccine Success

How to distribute jabs efficiently; plus adding 28 to 47

Wales has given one vaccination dose to a larger proportion of their population than almost anywhere else. In the UK as a whole, 75 percent of adults have received at least one dose of vaccine - which is among the largest proportions in the world. But Wales is well ahead even of that benchmark, at 85 percent. We look at the data to see how they achieved this. 

Plus, a simple sum has been doing the rounds on social media recently: 28 + 47. Tim Harford talks to mathematician Katie Steckles about the different ways of tackling it in your head.
