Flu season is upon us: what you need to know
Who is most at risk of serious illness from flu?
- People over 65
- Babies under 6 months
- Children under 5 years
- Pregnant women
-
People with long- term health conditions and other risk groups (such as; close contacts of immunocompromised individuals, or those who are rough sleepers or using homeless hostels or night-shelters)
But the good news is they can help protect themselves by getting the flu vaccine. Mothers can protect their babies under 6 months by getting the vaccine in pregnancy.Flu is not just a heavy cold. It comes on suddenly, with symptoms like high fever, body aches, and extreme tiredness. You’re likely to spend several days in bed feeling very unwell.
Can flu lead to serious illness?
Some people are hospitalised each year due to complications. Last winter, flu was linked to around 8,000 deaths in the UK.
I'm healthy. Do I still need it?
If you're eligible, you're at greater risk of becoming seriously ill if you catch flu.This includes older adults, people with long-term health conditions, pregnant people, and frontline health and social care workers.
Can the flu vaccine give me flu?
No. It cannot give you flu. You might have a sore arm or a slight temperature afterwards—these are normal signs your body is building protection.
The vaccine works by training your immune system. It helps your body produce antibodies that fight the flu virus if you’re exposed later.
It takes up to 2 weeks for the vaccine to become effective. Get vaccinated as early as possible to stay protected throughout flu season.
I had the vaccine last year. Why do I need another one?
Flu strains change annually and protection reduces over time, so new vaccines are developed to match the circulating viruses.
Pregnant people can get vaccinated at any stage of pregnancy. It protects both you and your baby—during pregnancy and in the first few months after birth.
Your vaccination protects others too. By getting vaccinated, you help shield elderly relatives, people with long-term conditions, and your wider community.
When and where can I get vaccinated?
