A fifth of patients aged 65 and over in Oxfordshire have not been vaccinated against influenza, new figures show.

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.

But new figures show 81 per cent of 139,000 patients aged 65 and over in Oxfordshire had received a vaccine as of the end of November, with the remainder more vulnerable to the illness.

This was higher than the national average – 76 per cent of people over 65 had been given a vaccine across England as of 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.

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 44 per cent vaccinated in Oxfordshire. Meanwhile, uptake among pregnant women was at 32 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," she added.

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 added: "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.

Ansaf Azhar, Oxfordshire County Council’s director for public health, said: “While flu and COVID is often just an unpleasant inconvenience, they can be dangerous and even life-threatening for some people, particularly those with certain health conditions.

“The vaccination programme aims to provide those who need the most protection with the help they need as soon as possible.

"Getting the vaccine not only gives you extra protection but also helps to reduce the risk of passing on the virus to someone else.

"Please do come forward for your vaccination when invited to keep yourself and those around you safe."
