Flu vaccination is important because:
- if you’re at higher risk from coronavirus, you’re also more at risk of problems from flu.
- if you get flu and coronavirus at the same time, research shows you’re more likely to be seriously ill.
- it’ll help to reduce pressure on the NHS and social care staff who may be dealing with coronavirus.
For the 24/25 flu season you are eligible if:
- aged 2 and 3 years on 31 August 2024

Most adults can have the flu vaccine, but you should avoid it if you have had a serious allergic reaction to a flu vaccine in the past.
You may be at risk of an allergic reaction to the flu vaccine injection if you have an egg allergy. This is because some flu vaccines are made using eggs.
Ask a GP or pharmacist for a low-egg or egg-free vaccine.
If you are ill with a high temperature, it’s best to wait until you are better before having the flu vaccine.
The flu vaccine gives the best protection against flu.
Flu vaccines help protect against the main types of flu viruses, although there’s still a chance you might get flu.
If you do get flu after vaccination, it’s likely to be milder and not last as long.
Having the flu vaccine will also stop you spreading flu to other people who may be more at risk of serious problems from flu.
It can take 10 to 14 days for the flu vaccine to work.
Flu vaccines are very safe. Most side effects are mild and only last for a day or so, such as:
- slightly raised temperature
- muscle aches
- sore arm where the needle went in – this is more likely to happen with the vaccine for people aged 65 and over.
Try these tips to help reduce the discomfort:
- continue to move your arm regularly
- take a painkiller, such as paracetamol or ibuprofen – some people, including those who are pregnant, should not take ibuprofen unless a doctor recommends it.
It’s very rare for anyone to have a serious allergic reaction (anaphylaxis) to the flu vaccine. If this does happen, it usually happens within minutes.
The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.
There are several types of injected flu vaccine. None of them contains live viruses so they are called inactivated vaccines.
If you’re eligible for the flu vaccine on the NHS, you’ll be offered one that’s most effective for you, depending on your age:
- adults aged 18 to 64 – there are different types, including low-egg and egg-free ones
- adults aged 65 and over – the most common one contains an extra ingredient to help your immune system make a stronger response to the vaccine
Talk to a GP, practice nurse or pharmacist for more information about these vaccines.
