A warning has been issued to parents going on holiday with their children this summer.
Dr Zoe Williams appeared on yesterday's edition of This Morning to discuss falling rates in the uptake of the MMR vaccine. The NHS say children should get two doses of the vaccine to be protected from measles, mumps and rubella.
The first dose should be administered when a child is around one years old - and the second dose when a child is around three years and four months old. Dr Zoe was concerned as she revealed one in 10 children are set to start school without being fully vaccinated.
