Seasonal flu is a highly infectious disease caused by a virus. It occurs every year, usually in winter, and can make even healthy people feel very unwell for a week or more. In the most serious cases, flu can bring on pneumonia, or other serious infections which can, in extreme cases, result in death.
Most viruses can be identified in advance and vaccines can be produced that closely match them. Vaccination is available to help protect people who are more at risk of flu or the complications of flu.
The vaccine is quick and free. If you think you are eligible for the flu vaccination or if you want more information contact your GP surgery.
More information about this year's seasonal flu vaccination programme, including information leaflets, symptoms of flu and at risk categories, is available from NHSinform NHSinform.scot/flu
