THE UK Health Security Agency (UKHSA) North West is today urging parents to prioritise vaccine catch-up appointments during the summer break, with latest data showing continued high levels of measles cases amid fears of a further surge once the new school term begins.

Measles activity has increased since April 2025, and the UKHSA is continuing to oversee the public health risk assessment and working with NHS North West and local partners on the response.

The latest monthly update on measles cases in England, published today, shows that an additional 145 measles cases have been reported across the country since the last publication on 3 July 2025. 

Cases continue to predominantly be in children under the age of 10 years, with London and parts of the North West driving the increase most.

The latest measles epidemiology report on the UKHSA Data Dashboard, released today, reports that between 1 January and 28 July 2025, the North West has recorded 111 confirmed measles cases, representing 16% of England's total of 674 cases. This makes it the 2nd most affected region after London (which has 322 cases, 48% of the total).

The North West appears to be experiencing ongoing measles transmission, particularly affecting children aged 10 and under.

There has also been a global increase in measles cases, including in Europe, over the last year. UKHSA is concerned that holiday travel and international visits to see family this summer could lead to rising measles cases in England when the new school term begins.

Dr Merav Kliner, Regional Deputy Director for UKHSA North West, said:- “The summer months offer parents an important opportunity to ensure their children's vaccinations are up to date, giving them the best possible protection when the new school term begins.  It is never too late to catch up. Don’t put it off and regret it later. Measles spreads very easily and can be a nasty disease, leading to complications like ear and chest infections and inflammation of the brain, with some children tragically ending up in hospital and suffering life-long consequences. 2 doses of the measles, mumps and rubella (MMR) vaccine is the best way to protect yourself and your family from measles. Babies under the age of 1 and some people who have weakened immune systems can’t have the vaccine and are at risk of more serious complications if they get measles. They rely on the rest of us getting the vaccine to protect them.”

Dr Linda Charles-Ozuzu, Regional Director of Commissioning at NHS England - North West, said:- “The MMR vaccine remains the best way to protect children from measles, which is highly contagious and can be very dangerous in some cases. As the summer holidays continue, people may start travelling and visiting family and friends who could be vulnerable – such as babies, toddlers and the elderly so it's more important than ever that children are protected. Measles is a preventable disease, and two doses of the vaccine are enough to give lifelong protection from measles, mumps and rubella, so please take up the offer of vaccination if your child has yet to have one, or both of the vaccines.”

The 1st MMR vaccine is offered to infants when they turn 1 year old, and the 2nd dose to pre-school children when they are around 3 years and 4 months old. 

Around 99% of those who have 2 doses will be protected against measles and rubella. Although mumps protection is slightly lower, cases in vaccinated people are much less severe. 

Anyone, whatever age, who has not had 2 doses can contact their GP surgery to book an appointment.
