The UK has lost its status as a measles-free country after a rise in deaths from the disease and fall in the proportion of children having the MMR jab in recent years.
The World Health Organization (WHO) said it no longer classified Britain as having eliminated measles because the disease had become re-established.
The UK is one of six countries in Europe and central Asia that the WHO says is no longer measles-free, the others being Spain, Austria, Armenia, Azerbaijan and Uzbekistan.
The WHO had adjudged the UK to have eliminated the disease between 2021 and 2023, but recent increases in the number of recorded cases – there were 3,681 in 2024 – and rises in the number of outbreaks and deaths has led to a rethink.
Doctors, public health experts and local councils said the WHO’s decision reflected the country’s diminishing uptake of the MMR vaccination, which they linked to vaccine hesitancy and parents’ difficulty in getting appointments for their child to be immunised.
Dr Simon Williams, a public health researcher at Swansea University, said: “It’s sad to see the UK losing its measles elimination status, although it’s not surprising given outbreaks in recent years. Measles is an eminently preventable disease but vaccine coverage of MMR has declined. We are seeing vaccine hesitancy growing in the UK, as in many countries, and social media-based conspiracies about MMR are a factor.”
He said the decision by the UN health body “is a wake-up call that more needs to be done” to get rates of MMR in children in the UK back up to the 95% that the organisation says is needed to eliminate measles, mumps and rubella altogether through herd immunity.
