If you're a frontline health and social care worker, your employer should offer you a flu vaccine. They may give the vaccine at your workplace.

You can also have an NHS flu vaccine at a GP surgery or a pharmacy, if you're a health or social care worker employed by a:

• registered residential care or nursing home
• registered homecare organisation
• hospice

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're ill with a high temperature, it's best to wait until you're 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. All adult flu vaccines are given by injection into the muscle of the upper arm.

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
