Flu Vaccination
Published: 24 November 2025
Message from the Director of Public Health:
Flu is now circulating in the community with the number of people infected higher than we usually see at this time of the year. The main virus circulating is a strain associated with more severe illness and higher death rates than other types of flu, particularly in the elderly. Experts nationally are predicting that we are likely to see a worse flu season than we’ve experienced for many years. We’re asking you to please share this message with the people you support and work with.
The flu vaccination remains the best protection against influenza. It takes about two weeks following the flu vaccination to build up immunity against the virus, so it’s important that people book as soon as you can.
Flu is highly infectious and can lead to serious illness. Remember to get your flu vaccine this year to protect yourself and others around you.
Those who are most at risk of serious illness can get it for free - here’s how you can book your free flu vaccine today:
• Speak to your GP practice
• Online, search ‘NHS pharmacy vaccine’
• NHS app
• Call 119 (translator available)
Even if you can't get a free vaccine, you can still pay for one from a participating local pharmacy.
