Flu can make you feel really poorly. But for some people, like older adults, pregnant women, or those with health problems, it can be very serious.
Every winter, lots of people get very unwell from flu and some end up in hospital.
Vaccines are the best way to protect against the flu – they help stop it from spreading and keep you and others well.
Flu spreads more in winter because we’re indoors more. That’s why it’s good to get your jab before the cold weather starts.
Even if you’ve had the flu or the jab before, you still need it again. The flu virus changes every year, and your protection fades over time.
