The cold weather has arrived and, along with the harsh winds and rain, comes the sniffles, coughs and colds.
While you may feel like battling it out, the last thing you should do is ignore the symptoms - like fever, muscle aches and pains, sweating and a dry, chesty cough.
The flu is highly infectious and can be passed through coughs, sneezing or by touching areas infected by people who already have it.
Once you are injected the vaccine will protect your body for six to 12 months.
The jab is available now.
What is the flu jab?
Flu shots, which are medically called influenza vaccines, stimulate your body's immune system and encourage antibiotics to attack any virus in your system.
The vaccine is usually injected into your arm. Once you are exposed to the virus, after you've had the injection, your immune system will recognise it and fight against it.
Can I get a free flu jab?
The NHS offers it free to people who are more susceptible to being at risk of going on to develop more serious conditions if they catch flu.
If you are eligible you can get a free flu jab from Boots pharmacies and your local GP clinic. You can book an appointment for your vaccination at Boots here.
65 and over
You are eligible for the flu vaccine if you are aged 65 and over. But in order to qualify you must have been born on or before March 31 1952.
It also includes people living long-term in a residential care home.
The vaccine may make you feel weak and poorly for a few days, after having the injection, but this will soon pass.
It is also free for pregnant women, to help safeguard against complications that can arise and affect both mum and baby.
However, new figures reveal more than half (56%) of mums-to-be did not take up the offer of the free vaccine last year.
Boots is encouraging more pregnant women to consider getting the jab this winter, and reminding them they can get it free.
Children over the age of six months with a long-term health condition are eligible for the jab.
As are kids over the of four in school years one, two and three. Usually they are given the vaccine through a nasal spray.
If your child is aged between 2 to 17, and has a long-term health condition, such as diabetes they are at higher risk of getting the flu.
The NHS offers the jab to anyone with a serious long-term health condition.
- chronic (long-term) respiratory diseases, such as asthama
- bronchitis or chronic obstructive pulmonary disease
- chronic heart disease, such as heart failure
- chronic kidney disease
- chronic liver disease, such as hepatitis
- chronic neurological conditions, such as Parkinson's disease of motor neurone disease
- problems with your spleen – for example, sickle cell disease or if you have had your spleen removed
- a weakened immune system as the result of conditions such as HIV and AIDS or medication such as steroid tablets or chemotherapy
If I am not eligible for a free jab can I still have one?
Yes, you can but you will have to pay for it and you won't be able to have it done at your GP surgery.
Asda Pharmacy provides the cheapest jab for £7 and you can also get it done at selected Tesco's for £9.
Boots also do jabs, for people that aren't eligible for the free shot, for £12.99.
