THE UK Health Security Agency (UKHSA) is urging parents to prioritise measles vaccination catch-up appointments over the summer, warning of a potential surge in infections when schools return in September.
New figures released today show a continued rise in measles cases across England. A total of 674 laboratory-confirmed cases have been reported so far in 2025, with 145 new cases since the last update on July 3rd. Most infections are in children under the age of 10 years, with London, the North West, and East of England worst affected. Nearly half of all cases (322) have occurred in London alone.
UKHSA officials are particularly concerned that international travel and family visits during the summer holidays could lead to increased transmission, especially with measles cases rising globally, including across Europe.
Vanessa Saliba, Consultant Epidemiologist at UKHSA, said the summer break presents a crucial opportunity for parents to ensure children are fully protected before the school year begins. “It is never too late to catch up,” she said. “Measles spreads easily and can be serious, even life-changing. Vaccination is the best way to protect your child and others.”
The MMR (measles, mumps and rubella) vaccine is free on the NHS. The first dose is given to infants around their first birthday, and the second dose is offered at around 3 years and 4 months of age. Two doses offer around 99% protection against measles and rubella.
Amanda Doyle, National Director for Primary Care and Community Services at NHS England, said parents should check their child’s vaccination records before any travel or the start of term. “While tens of thousands of extra MMR jabs were delivered last year, too many children remain unvaccinated,” she said, adding that efforts are ongoing to reach more families through mobile clinics and catch-up sessions.
Adults who are unsure of their MMR status or have missed doses can also contact their GP to get vaccinated.
