The MMR jab protects against measles, mumps and rubella
Children should be vaccinated with two doses of the MMR vaccine after an outbreak of measles in parts of Cheshire, health officials have said.
Three cases of the illness have been confirmed by laboratories, with a further 11 possible cases, across Sandbach and Middlewich.
The Health Protection Agency (HPA) said parents should make sure children have double vaccines following the outbreak.
One youngster was treated in hospital but has since recovered and gone home.
The jab protects children against measles, mumps and rubella.
People of any age can contract measles but it is most common among those aged one to four years old.
