Following an early surge, flu cases are beginning to level off for the first time this year, but the UKHSA is warning people not to become complacent as the peak might not be finished yet. This is particularly concerning as there's a restricted time to receive the flu jab before the festive period.

The agency outlined four straightforward measurespeople can adopt to curb the transmission of flu during their Christmas celebrations. Some people may also face a greater risk of serious complications from the flu and will need to implement additional safeguards. This includes:

"With Christmas just around the corner, it's reassuring to see that flu levels are now starting to stabilise," Dr Alex Allen, Consultant Epidemiologist at UKHSA, said. "But flu is notoriously unpredictable and can bounce back and peak a second time in the new year."

He added: "So we're urging people to continue taking sensible steps over the festive period to help stop the spread. There are simple steps we can all take to protect one another when mixing indoors.

"For anyone eligible who is still not vaccinated, it's not too late to get protected for the rest of the winter, but time is running out. Please make an appointment as soon as you can as vaccination can make all the difference in preventing severe illness and hospitalisation.

"By continuing to take these precautions, we can all do our bit to reduce the chances of another spike." People who are presently feeling unwell, especially those experiencing a high temperature, are recommended to delay receiving the flu jab until they have recovered.

The flu vaccination is accessible to most people free of charge through the NHS. Appointments can be arranged via your GP practice, onlinebooking systems, or at selected pharmacies offering walk-in services.

Those at heightened risk of flu complications are strongly encouraged to receive the vaccination. This includes all people aged over 65, expectant mothers, young babies, and people with specific chronic health conditions.

Dr Allen continued: "For children who missed out on their school immunisation programme, parents are reminded that they can still get them vaccinated in local community clinics. Pregnant women can also get vaccinated through maternity services."

Flu jabs remain available through the NHS until March 31, 2026, though health experts advise securing your vaccination at the earliest opportunity to ensure protection throughout the winter months.
