Vaccination Info




Vaccination can help ‘outsmart 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 can help children to build immunity.1,2

  • The NHS in England continues to provide the free nasal spray flu vaccine to eligible children as part of the childhood national immunisation programme.3,4
  • In England, a nasal spray flu vaccine is provided to children aged 2-3 at their GP surgery and school-aged children in reception class and years 1-5.5 This may vary in some areas throughout the UK.
  • Because the main flu viruses change each year, all flu vaccines need to be given each year, including a nasal spray flu vaccine.2,6

How safe is the vaccine?

In the UK the nasal spray flu vaccine has been available since 2013 and it continues to be recommended for the NHS national vaccination programme.3,5,7

Are there side effects?

The flu vaccine for children has been well tolerated6 by most children but some may experience side-effects.1,2

Serious side-effects are uncommon. Children may develop a runny or blocked nose, headache, general tiredness and some loss of appetite.1,3 However, these very common side effects are much less serious than developing flu or complications associated with flu.1

Very common side-effects may affect 1 in 10 people.3
