More than a quarter of young children in London are unvaccinated against measles, new figures show.
Data published by the NHS shows that 26.7 per cent five-year-olds in the capital have not received two doses of the MMR vaccine in 2023/24, the lowest uptake of any region in England.
It is 16 per cent lower than the North East, which has the highest uptake.
Analysis of the figures reveals that London's vaccination rate is the lowest since 2009/10, when it stood at 72.2 per cent. The rate peaked at 81.1 per cent in 2015/16 but has declined since.
The MMR vaccine is given to children to protect against measles, mumps and rubella as part of the NHS routine vaccination schedule. Children receive their first dose aged 1, and their second dose aged 3 years and 4 months.
In January, NHS England launched a vaccination campaign in London allowing children to book an MMR jab through pop-up clinics at schools amid fears of a resurgence of the virus in the capital.
Measles spreads very easily and can cause serious health problems, including meningitis and pneumonia. It usually starts with cold-like symptoms, followed by a rash a few days later.
In July 2023, the UK Health Security Agency (UKHSA) predicted that low vaccination rates in London could lead to an outbreak of up to 160,000 cases.
The World Health Organisation (WHO) says to achieve herd immunity, at least 95 per cent of children should receive their set of vaccine doses for each illness.
None of the main childhood vaccines in England reached the 95 per cent uptake target in 2023/24, according to the figures, reflecting an ongoing struggle to immunise children following disruption caused by the Covid pandemic.
The UKHSA is urging parents to check their children’s vaccinations are up to date amid fears of a back-to-school surge of diseases like measles and whooping cough due to falling vaccine rates.
Dr Vanessa Saliba, UKHSA consultant epidemiologist, said: “As a mum and doctor, I know the additional stress that comes with having a sick child.
“I encourage all parents to take up the offer of vaccinations for their children at the right time, to give them the best protection from preventable diseases.
“Childhood vaccines prevent babies and children from suffering needlessly and can even be life-saving.”
Dr Saliba said she was pleased that parents whose children have missed vaccines are coming forward in the light of campaigns, but she added: “We are a long way from ensuring all are protected and safe.”
“If you’re not sure if your child is up to date with all their vaccines, check their Red Book or contact your GP practice, who can book an appointment if needed. Don’t put it off, please act today.”
