Having a flu vaccine will help protect your child from flu. Most children and young people have their vaccine as a quick and painless nasal spray.
Protection starts around two weeks after having the vaccine. The vaccine usually offers children good protection against flu.
It also helps reduce the chance of children and young people spreading flu to others who are at greater risk from flu, such as young babies, grandparents, and those with long-term health conditions.
Some people still get flu even after having a flu vaccine, but often with milder symptoms. Flu vaccines do not protect against colds, other respiratory viruses or other winter illnesses.
