Parents across North Wales are being urged to make sure children are up to date with both doses of the MMR vaccine after an outbreak of measles.

Polio has been eradicated across Europe because of vaccination. If 95 per cent of children in Europe were vaccinated with MMR, measles could also become a disease of the past.
The MMR vaccine is safe and effective and protects against mumps and rubella as well as measles. Although the first dose should be given just after one year of age and the second before a child starts school, it is never too late to catch up.
