An outbreak of measles on the scale of that currently happening in Wales is unlikely in Devon, according to the county's Director of Public Health.
It comes as a national programme is launched to immunise a million children who missed out on the Measles, Mumps and Rubella vaccine a decade ago.
Dr Virginia Pearson says the records show that there was a sufficient take-up of the MMR vaccine across the county, to prevent a large-scale incidence of the illness.
But there are pockets where fewer children were immunised during the 1990s, when parents were deterred by the now discredited link between MMR and autism.
Those affected are now likely to be aged between 10 to 16 - and parents of children in that age group are urged to get them vaccinated now.
