title: Are booster doses of poliovirus vaccine necessary?
abstract: In this issue of VACCINE, Böttiger points out that 'When the booster dose of polio vaccine at the age of 6 years was introduced (in Sweden) in the 1960s ... neither the necessity, nor the appropriate age for a booster had been scientifically evaluated'. If such a scientific evaluation were to be made now, what insights might emerge that would influence our thinking about booster doses and the associated implications for effective vaccination programmes and policy?
