Flu vaccination is available every year on the NHS to help protect adults and children at risk of flu and its complications.
Flu can be unpleasant, but if you are otherwise healthy it will usually clear up on its own within a week.
However, flu can be more severe in certain people, such as:
Anyone in a risk group is more likely to develop potentially serious complications of flu, such as pneumonia (a lung infection), so it's recommended that they have a flu vaccine every year to help protect them.
Who should get the flu vaccine?
The flu vaccine is routinely given on the NHS to:
For 2018, there are 3 types of flu vaccine:
If your child is aged between 6 months and 2 years old and is in a high-risk group for flu, they will be offered an injected flu vaccine as the nasal spray is not licensed for children under 2.
65 and overs and the flu vaccine
You are eligible for the flu vaccine this year (2018/19) if you will be aged 65 and over on March 31 2019 – that is, you were born on or before March 31 1954. So, if you are currently 64 but will be 65 on March 31 2019, you do qualify.
How effective is the flu vaccine?
Flu vaccine is the best protection we have against an unpredictable virus that can cause unpleasant illness in children and severe illness and death among at-risk groups, including older people, pregnant women and those with an underlying medical health condition.
Studies have shown that the flu vaccine will help prevent you getting the flu. It won't stop all flu viruses and the level of protection may vary, so it's not a 100% guarantee that you'll be flu-free, but if you do get flu after vaccination it's likely to be milder and shorter-lived than it would otherwise have been.
There is also evidence to suggest that the flu vaccine can reduce your risk of having a stroke.
Over time, protection from the injected flu vaccine gradually decreases and flu strains often change. So new flu vaccines are produced each year, which is why people advised to have the flu vaccine need it every year too.
Flu vaccine side effects
Serious side effects of the injected flu vaccine are very rare. You may have a mild fever and aching muscles for a couple of days after having the vaccine, and your arm may be a bit sore where you were injected.
Side effects of the nasal spray vaccine may commonly include a runny or blocked nose, headache, tiredness and some loss of appetite.
How safe is the flu vaccine?
The flu vaccines used in the national programme have a good safety record.
When to have a flu vaccine
The best time to have a flu vaccine is in the autumn, from the beginning of October to end of November, but don't worry if you've missed it, you can have the vaccine later in winter. Ask your GP or pharmacist.
The flu vaccine for 2018/19
Each year, the viruses that are most likely to cause flu are identified in advance and the World Health Organization (WHO) recommends which type of flu virus strains to include in the vaccine.
