Vaccination Info




Defending your child against flu

The nasal spray flu vaccine offered to eligible children, as part of the NHS childhood flu vaccination programme, contains live viruses that have been weakened to help prevent them from causing flu and to help children to build up immunity. It does this in a similar way to natural infection, but without an actual flu infection.1,2 If a child is not eligible for a nasal spray flu vaccine, they may be offered an alternative injectable vaccine.3

  • This flu season, the NHS national flu immunisation programme will be extended to more children than ever before.3
  • For the first time this year, the immunisation programme in England will include children in school year 6.3
  • In England, a nasal spray flu vaccine is available to eligible children aged 2-3 at their GP surgery and in schools for eligible children aged 4-10 on 31 August 2019, in reception class and years 1-6.4 This may vary in some areas throughout the UK.
  • Flu viruses change continually, so vaccination is needed every year.2,5
