Vaccine Benefits

  • It is free in Ontario for children 6 months of age and older.

  • The vaccine helps a child’s immune system prevent flu but cannot give the flu. Children can get very sick from a flu infection.

Choose the Vaccine for Your Child 2 to 17 Years Old

There are two types of vaccines for children 2 to 17 years of age. They are given as a needle or a spray in the nose. Canadian experts advise that either vaccine can be used in children of this age.

Children under 9 years of age, getting the flu vaccine for the first time, will need a second dose at least four weeks after the first dose.

Children 6 months to less than 2 years can only receive the vaccine, given as an injection.
