Why is it important to get a flu vaccine every year?

The flu illness is caused by a virus. The flu vaccine contains three types of influenza viruses. It is updated every year to match the specific types of the flu virus that people are getting sick with. It is important to get the current vaccine each year to protect you and your child against the type of virus that is most likely to cause the flu illness this year. 

Why do some children need 2 flu vaccines and others only need vaccine?

Children ages 6 months to 8 years will need 2 doses of the flu vaccine if they are getting the flu vaccine for the first time.  The first dose will help the body’s immune system get ready to fight the flu.  The second dose provides the full protection against the flu viruses.  Only one dose is needed every year after. Children over the age of 8 have a stronger immune defense system and only need one dose of flu vaccine every year.

Is it every too early or too late to get the flu vaccine?

You should try to get the vaccine each fall as soon as it is available.  The vaccine should not wear off before the end of flu season.  Getting the vaccine as early as September or October is okay. If you do not get the vaccine before the end of December, it is not too late.  You should try to get it when you can.  It is better to have protection against the flu, even late in the season.
