Over sixty fives in Wales are being warned they could be at risk if they don't get a flu vaccine this winter.
Last year, a third of older people missed out on their free flu jab. The vaccine can help protect against serious complications.
Flu can be very serious for older people, and the annual 'Beat Flu' immunisation programme is now underway throughout Wales.
It encourages people most at risk of serious complications from flu to protect themselves with a free flu jab.
Those at risk includes pregnant women and those with certain long term health conditions, such as diabetes.
Public Health Wales are warning people about the dangers of flu with the message “Beat flu before it beats you!”
The virus changes from year to year, so having a flu vaccine annually is the best way to protect against catching or spreading flu, according to Public Health Wales.
You can have the jab at your GP and many community pharmacies also offer the vaccine.
Flu spreads when someone with the virus coughs or sneezes, releasing infected droplets into the air. If you touch a contaminated surface, you may also catch the flu. It can spread quickly in places such as hospitals, care homes and schools.
Children aged two and three are being offered a nasal spray to protect them against the virus, while four to seven year olds are being offered vaccines at school.
