The UK Health Security Agency has declared a national incident due to rising measles cases, with the North East and North Cumbria having the highest MMR uptake in England but falling below the 95% target for the second dose. The NHS is urging parents and caregivers to ensure children are fully vaccinated, as measles is highly infectious and can lead to severe complications. The decline in MMR vaccination is linked to a rise in measles cases, which has led to national alarms in the UK and the US. Hywel Dda UHB is urging unvaccinated children, teenagers, and adults to get vaccinated to protect against measles outbreaks.
