As winter approaches, health authorities in England are raising urgent warnings about a resurgence of measles, a highly contagious virus that poses significant risks, especially to children. Despite being easily preventable with the MMR vaccine, the virus continues to affect a substantial number of people, with more than 770 laboratory-confirmed cases reported since the start of 2025. Public health officials stress the importance of vaccination and catching up on missed doses as the season's indoor conditions and the new school term contribute to the spread.

The UK Health Security Agency (UKHSA) has highlighted that the virus thrives during colder months due to people spending more time indoors in close proximity, thus accelerating transmission. This seasonality effect, combined with children returning to school, creates a fertile environment for outbreaks. The London and North West regions have been particularly affected, though data show outbreaks have begun to decline following a summer spike. Nonetheless, officials remain vigilant about the potential for further increases as winter progresses.

Measles can cause serious complications such as pneumonia and meningitis if the infection spreads beyond the initial symptoms. The MMR vaccine, offered free through the NHS, provides robust protection. It is administered in two doses, typically at one year and again at around three years and four months old. The UKHSA and NHS England have been emphasizing the need for parents and guardians to ensure children receive both doses. Yet, vaccination coverage remains insufficient in some areas, leaving a significant number of children vulnerable.

Recent government data reveal that more than 10% of children under five in England have not received the full MMR vaccination. This gap increases the risk of outbreaks in settings like nurseries and schools where children are in close contact. For example, NHS England Midlands reported that nearly a quarter of children starting school were not fully protected against measles. This is particularly concerning given ongoing outbreaks in urban centres such as Coventry, Birmingham, Leicester, London, and Greater Manchester.

The situation has prompted urgent calls from health officials. The UKHSA’s Chief Executive warned earlier this year that without increased vaccination efforts, measles outbreaks could expand further. The agency has urged parents of infants who missed vaccinations as well as unvaccinated individuals of all ages to come forward for the vaccine. The warning is underscored by data showing that most recent measles cases are in children under 10, including several who had received only one dose or, in rare cases, even two doses, highlighting the importance of maintaining high vaccination coverage.

Travel-related risks have also been a concern, with the UKHSA cautioning that holiday periods can contribute to surges in cases. Parents are advised to ensure children are vaccinated before travelling to reduce importation and spread of the virus. Furthermore, with the new school term underway, health authorities are urging parents to prioritise vaccine catch-up appointments to prevent further increases.

According to official statistics, measles outbreaks remain a pressing public health issue in England during 2025. The combination of low vaccine uptake in some areas, seasonal factors, and close contact environments creates a recurring challenge. Authorities continue to remind the public that measles is preventable, that vaccines are safe and effective, and timely vaccination remains the best defence.
