Parents have been urged by a council to get their children vaccinated against measles after a “significant” outbreak.
One in 10 children in Hertfordshire were at risk of catching the virus as they were not up to date with their MMR vaccine, according to Hertfordshire County Council.
Sarah Perman, the authority’s director of public health, said the low uptake rates were a concern due to the area’s close proximity to Enfield, north London, where an outbreak has been affecting several nurseries and schools.
“Measles is a nasty illness. Sadly, some children who catch [it] can develop serious complications. Our vaccination rates are still not as high as they should be,” Perman said.
