The worst areas for childhood vaccinations against measles, mumps and rubella (MMR) have been revealed - as London faces a surge in measles cases and warnings sent to parents over possible isolation periods for unvaccinated children.
The UK Health Security Agency (UKHSA) says the risk of a measles epidemic across the UK is considered small, however in London, where uptake in the vaccinations is low, an outbreak of between 40,000 and 160,000 cases could occur.
