The flu jab reduces your risk of getting the flu and having to experience symptoms and take time to recover.
Although the flu jab does not prevent 100% of all flu cases, people who have been vaccinated and who catch a strain of the flu they are vaccinated against tend to have less severe symptoms which usually improve within a shorter period of time.
The flu can cause serious complications in children, the elderly, those with a weakened immune system and pregnant women. For these groups, the flu jab offers protection not only from the flu but helps to reduce the risk of more serious illness and the secondary complications of flu, like pneumonia.
You need to get vaccinated every year in order to stay protected – the flu virus is constantly changing, and the vaccine is formulated every year to remain effective against the most common strands of the flu. The best time to get the vaccine is before the beginning of the flu season, but you can also get it later in winter.
