Urgent action is needed so children in Wales are fully vaccinated for measles, the chief medical officer has warned.

Sir Frank Atherton said outbreaks could become more frequent unless uptake of the measles, mumps and rubella (MMR) vaccine increased.

He said parents should arrange jabs as soon as possible if their children are not fully vaccinated.

The World Health Organization says 95% should be double vaccinated by the age of five but the UK is below the target.
