The UK Health Security Agency (UKHSA) warns that many individuals at risk may be unaware they are eligible for a flu vaccine.
Recent data shows that fewer than a third (28.9%) of people with one or more long-term health conditions (LTHCs) have received a flu vaccine. Among 9 million people under 65 in clinical risk groups eligible for vaccination, only 40% were vaccinated during the 2024–2025 season, leaving over 5 million unprotected.
Flu vaccine uptake is higher in adults aged 65 and over, with 61.5% vaccinated so far this year and an overall 74.9% vaccinated in the previous year. However, many older adults with LTHCs remain unvaccinated.
For some clinical groups, the risk of influenza-related mortality is significantly greater compared to the general population.
