Last winter, 3,800 people died from flu in England. But it is estimated that flu vaccinations prevented an estimated 104,000 hospital admissions and 7,100 deaths.
The NHS injectable flu vaccines do not contain any live virus so cannot give you flu. Vaccines work by teaching your body to recognise and deal with viruses in the future. Side effects of the vaccine are usually mild and show that your body is producing antibodies to protect itself.
For people most at risk, having your free NHS flu vaccine reduces your chances of becoming seriously ill. It also helps you recover faster if you do catch the virus and it lowers the risk of needing hospital care.
