There were two cases of measles in Doncaster in the year ending June 30, according to figures released by Public Health England.
Close monitoring of measles cases continues as the MMR catch-up campaign continues.
The campaign aims to prevent measles outbreaks by giving MMR to as many unvaccinated and partially vaccinated 10-16 year olds as possible.
Dr Stephen Morton, Centre Director for PHE in Yorkshire and the Humber, said: “The number of measles cases is remaining stable in the Yorkshire and Humber area at the moment, but we are still seeing a small number of cases every month. We are making good progress towards the 95 per cent target, but there still remains a number of 10-16 year olds within the Yorkshire and the Humber area, together with some younger children and adults who are under-vaccinated.
“While it’s too early to say the MMR catch-up campaign is responsible for the overall decline number of measles cases nationally, we can say definitively that children who have not had the MMR vaccine remain at high risk of catching the disease.
“We’d urge parents of children that haven’t had the MMR vaccine to contact their GP and get them vaccinated.”
