Hundreds of confirmed cases of measles have been reported this year, raising concerns about low vaccination rates. Recent data indicates that 442 cases of measles have been confirmed through lab tests so far this year, with analysis revealing higher case numbers in areas with lower vaccination rates. This follows a report by the Mirror indicating that unvaccinated children could be sent home from school during local outbreaks.
Dr. Vanessa Saliba, a Consultant Epidemiologist at UKHSA, expressed alarm over the decline in MMR vaccine uptake in the last decade. Measles, being highly contagious, spreads through airborne or water droplets from infected individuals. The disease can be fatal and may lead to severe complications such as blindness, deafness, and brain swelling.
The MMRV vaccine, a combined NHS childhood vaccine protecting against measles, mumps, rubella, and varicella, is administered in a single injection. However, vaccine coverage has dropped below the 95% target recommended by the World Health Organization for achieving herd immunity.
Dr. Saliba emphasized the importance of the MMR or MMRV vaccine in safeguarding children against measles-related hospitalizations and long-term health issues. Ensuring children receive both doses of the vaccine before starting school is crucial in preventing measles outbreaks. The NHS is simplifying the vaccination process by offering the second MMRV dose earlier at the 18-month appointment to enhance uptake and support elimination efforts.
In Western Europe, measles continues to result in fatalities in approximately 1 in 5,000 cases. Following a discredited 1998 report linking the MMR vaccine to autism, vaccination rates declined, taking years to recover despite the report being debunked and the author being removed from the medical register.
Earlier this year, the World Health Organization confirmed the re-establishment of measles in the UK from 2024. The UK had previously eliminated measles from 2021 to 2023 before experiencing a decline in vaccination rates, currently at the lowest level in over a decade.
According to data from UKHSA, in 2024/25, only 91.9% of five-year-olds had received one dose of the MMR vaccine, the lowest level since 2010/11. Additionally, just 83.7% of five-year-olds received both MMR doses, marking the lowest level since 2009/10.
Some regions exhibit even lower vaccination rates, such as Enfield, where only 79.3% of children received the first MMR dose and 64.3% completed the course. Similarly, Hackney has a mere 58.3% of children fully protected, despite having the highest number of measles cases in England last year.
