From Geoff Harding, Sydney, Australia
Such is the power of the nocebo effect, it is arguably a mistake to read a list of possible negative side effects when you have to take a medication. When I had a covid-19 vaccine, I saw a wall poster listing possible side effects and advised the nurses it wasn’t necessarily a good idea to encourage people to read it. Of course, should side effects strike, seek medical advice (22 February, p 38).
