Nearly a third of patients aged 65 and over in Blackburn with Darwen have not been vaccinated against influenza, figures show.

NHS data shows 70 per cent of the 27,000 pensioners in the borough had received a vaccine as of the end of November, with the remainder unvaccinated and more vulnerable to the illness.

This was lower than the national average – 76 per cent of people over 65 had been given a vaccine across England by the end of November, leaving nearly a quarter of this group unvaccinated.

More recent figures – only available for England as a whole – show this figure has since increased slightly, to 77 per cent. However, the NHS warns this is a lower proportion than at the same point last winter.

The NHS offers free flu jabs to the most vulnerable patients – such as those in older age groups, with weaker immune systems, or pregnant women.

Jane Scattergood, senior responsible officer for the vaccination programme in Lancashire and South Cumbria, said: “Flu is always prevalent at this time of year, especially with people being together for festivities and attending large gatherings.

“We would encourage everyone who is eligible to get a flu vaccine while they can.

"Vaccines are available at a number of pharmacies in Blackburn on a walk-in basis until the end of January, and you can find their availability on the NHS website or ask your GP.

“Flu can make people really quite poorly, especially those with additional medical vulnerabilities or the elderly.

"By getting vaccinated, not only are you protecting yourself against the main types of flu viruses, but you are protecting those around you who may be vulnerable.”

Official guidance says vaccinations remain "critically important", reducing the burden on the health service as it deals with regular winter pressures and the continued fall-out of the coronavirus pandemic.

Vulnerable people under 65 had lower coverage, with 32 per cent vaccinated in Blackburn with Darwen.

Meanwhile, uptake among pregnant women was at 18 per cent at the end of November.

Caroline Abrahams, charity director at Age UK, urged older people to get vaccinated against flu and Covid-19.

She said: "Flu vaccines help protect against the main types of flu viruses and although there's still a chance we might get flu even after vaccination, the symptoms are likely to be milder and more short-lived.

"With all the worries about the rising cost of living and energy prices and with the additional pressures on the NHS at wintertime, it’s more important than ever to stay fit and well this year, and getting these vaccinations will help."

Dr Mary Ramsay, director of public health programmes at UKHSA, said infections are rising as people socialise indoors over the festive season.

"Nobody wants to get their new year off to a bad start, so be sure to gift yourself the best possible protection against flu and Covid-19 as we head into peak season."

She continued: "Pregnant women and those in clinical risk groups are at higher risk of complications from flu, but over 60 per cent of these groups remain unvaccinated, so we urge them to come forward."

Dr Ramsay said those eligible should speak to their GP – adding that many pharmacies offer free bookable and walk-in vaccinations.
