Here, I want to discuss the second point by invoking a famous epidemiological theorem called ‘Rose’s Paradox’, and urge that they should have a jab if possible.

Geoffrey Rose (1926–1993), CBE, is one of my academic heroes. He was a Professor of Epidemiology at the London School of Hygiene and Tropical Medicine. He is the author of the famous book, ‘The Strategy of Preventive Medicine’, which has been one of my bed reading books.
