How common is measles?
The World Health Organization confirmed that the UK eliminated measles in 2016.
This is because the MMR vaccine is highly effective and vaccine uptake has been very high in the UK for many years.
But this doesn't mean that measles has disappeared. Measles is common in many countries around the world, and currently there are several large measles outbreaks across Europe.
We'll continue to see imported measles cases in the UK, and anyone who hasn't had 2 doses of the MMR vaccine can catch it.
In 2016 there were more than 500 measles cases in England, many in teenagers and young people attending summer festivals who'd missed out on their MMR vaccine in childhood.
