Flu 2021/22

Just the Flu poster

Flu isn’t just a heavy cold

Flu occurs every year, usually in the winter, which is why it’s sometimes called seasonal flu. It’s a highly infectious disease with symptoms that come on very quickly.

Colds are much less serious and usually start gradually with a stuffy or runny nose and a sore throat. A bad bout of flu can be much worse than a heavy cold.

The most common symptoms of flu are:

  • fever,
  • chills,
  • headache,
  • aches and pains in the joints and muscles,
  • extreme tiredness.

Healthy individuals usually recover within 2 to 7 days but, for some, the disease can lead to hospitalisation, permanent disability or even death.

The harm flu can do

People sometimes think a bad cold is flu, but having flu can often be much worse than a cold and you may need to stay in bed for a few days. Some people are more susceptible to the effects of flu. For them, it can increase the risk of developing more serious illnesses such as bronchitis and pneumonia, or can make existing conditions worse. In the worst cases, flu can result in a stay in hospital, or even death.


How you catch flu

When an infected person coughs or sneezes, they spread the flu virus in tiny droplets of saliva over a wide area. These droplets can then be breathed in by other people or they can be picked up by touching surfaces where the droplets have landed.

You can prevent the spread of the virus by covering your mouth and nose when you cough or sneeze, and you should wash your hands frequently or use hand gels to reduce the risk of picking up the virus.

But the best way to avoid catching and spreading flu is by having the vaccination before the flu season starts.


Those at increased risk from the effects of flu

Flu can affect anyone, but if you have a long-term health condition, the effects of flu can make it worse even if the condition is well managed and you normally feel well. You should have the free flu vaccine if you are:

  • pregnant

or have a long-term condition such as:

  • a heart problem
  • a chest complaint or serious breathing difficulties, including bronchitis, emphysema or some people with asthma
  • a kidney disease
  • lowered immunity due to disease or treatment (such as steroid medication or cancer treatment)
  • liver disease
  • had a stroke or a transient ischaemic attack (TIA)
  • diabetes
  • a neurological condition, such as multiple sclerosis (MS) or cerebral palsy
  • a learning disability
  • a problem with your spleen, such as sickle cell disease, or you have had your spleen removed
  • you are seriously overweight (BMI of 40 and above)

This list of conditions isn’t definitive. It’s always an issue of clinical judgement. Your GP can assess you to take into account the risk of flu making any underlying illness you may have worse, as well as your risk of serious illness from flu itself.


How we protect against flu

Flu is unpredictable. The vaccine provides the best protection available against a virus that can cause severe illness. The most likely viruses that will cause flu are identified in advance of the flu season and vaccines are then made to match them as closely as possible.

The vaccines are given in the autumn ideally before flu starts circulating. During the last 10 years, the vaccine has generally been a good match for the circulating strains.

Flu vaccines help protect against the main types of flu virus circulating.


Who can have a FREE flu vaccination

This year more people are eligible for the free flu vaccination. Below is a list of who those groups are and links to more information for those groups (more links to information will be added as they become available).
