LATEST figures have recorded two more cases of measles in Warrington and Halton on top of 35 in Cheshire and Merseyside between January and March this year.
A national catch-up programme to increase MMR vaccination uptake in 10 to 16-year-olds was launched earlier this year after an outbreak of the infection.
It is thought this age group is most at risk of measles after concern around the discredited link between autism and the jab was widespread.
Dr Paula Grey, chairman of the Cheshire and Merseyside directors of public health said: “Measles is very unpleasant and can lead to serious complications.
“I urge all parents whose children haven’t been vaccinated or have not had both doses of the vaccine, as well as older teenagers and young adults, to contact their surgery immediately to make an appointment.”
