Influenza cases are increasing across the UK, driven predominantly by the emerging H3N2 strain, also known as subclade k. According to recent data from the UK Health Security Agency (UKHSA), flu activity has intensified to medium levels nationwide.
Laboratory surveillance reports a slight dip in positive flu tests, with a weekly positivity rate of 13.9% in the week up to January 8, down marginally from the previous week. Hospital admissions related to influenza remain at medium levels, with an overall admission rate of 7.19 per 100,000 people.
While flu symptoms can be uncomfortable for many, certain groups face a higher risk of serious infection and complications. Young children, older adults, and individuals with weakened immune systems are among the most vulnerable and stand to benefit greatly from the free flu vaccination offered by the NHS.

Professor Meghana Pandit, NHS national medical director, warns, “The worst is far from over for the NHS this winter, with hospitals seeing a rise in flu and other respiratory virus admissions.” She urges people to seek medical care when needed and take advantage of available vaccination opportunities.
The flu vaccine boosts the immune system by exposing it to an inactivated version of the virus, enabling the body to recognize and fight real infection. It takes about 10 days after vaccination for protection to become effective. Importantly, the flu shot cannot cause the flu itself.
UK Health Secretary Wes Streeting reinforces this message: “Flu can be serious, especially for older people, young children, and those with underlying health conditions. Vaccination remains the best defense. I strongly encourage all eligible individuals to get their flu jab promptly.”
Eligibility for a free NHS flu jab includes six key groups. These include people who are:
- Aged 50 and over
- Pregnant women
- Individuals with certain long-term health conditions
- Residents in care homes
- Healthcare and social care workers
- Children aged 2 to 11 years
If you qualify for a free flu vaccine, you can book an appointment through your GP practice or visit participating pharmacies. NHS-approved pharmacies offer the vaccine free of charge to eligible individuals, and some accept walk-ins without pre-booking. Check locally for participating providers.
