Fall in child MMR vaccinations
The proportion of two-year-olds having the MMR vaccine has fallen, according to the NHS.
Between 2013-14 92.7 per cent of children in England had the vaccine. However, that figure dropped between 2014-15 to 92.3 per cent.
Parts of the West Midlands and northern England had more than 95 per cent of children immunised. However, in the south-east and some London boroughs the figure was below 80 per cent. The target rate is 95 per cent to stop the diseases spreading. Scotland, Wales and Northern Ireland all had figures above 95 per cent.
Coverage had increase every year since 2007-8 and was the highest it's ever been before the latest figures.
