Children aged 1 to 9 years old in London are being offered a dose of polio vaccine. For some children this may be an extra dose on top of their routine vaccinations. In other children it may bring them up to date with their routine vaccinations.
There are signs the virus may be spreading in London and the number of children vaccinated in London is lower than it should be. Boosting immunity in children should help protect them and reduce the risk of the virus continuing to spread.
If your child is eligible for an extra dose, the NHS will contact you to ask you to book an appointment for the vaccine.
