Influenza vaccine helps protect against flu caused by influenza virus in children aged 2 years and above and adults aged 49 years and below.
It works by getting your body to produce antibodies (proteins that are produced by the immune system which help fight infections) to protect you against the influenza virus.
Influenza vaccine is to be given as a spray into the nostrils. This medicine should not be injected.
Your doctor or nurse will administer the medicine for you.
Breathe normally while this medicine is being administered. There is no need to sniff or inhale during administration.
Administration of Influenza vaccine may need to be repeated each year.
In children less than 9 years of age, the total number of doses for the year will be decided by the doctor depending on the child's vaccination history.
For children who will be receiving more than 1 dose for the year, ensure that you keep all appointments with the doctor so that your child does not miss any doses.
If your child misses an appointment or misses an injection, alert your doctor or nurse.
Do not use Influenza vaccine if you ever had an allergic reaction (e.g. rashes, breathlessness, swollen eyes) to this medicine or eggs.
Do not use Influenza vaccine with aspirin (blood-thinning medicine or medicine used for pain and inflammation) in children and adolescents.

- history of Guillain-Barre syndrome (a rare disorder in which your body's immune system attacks your nerves)
- asthma or wheezing (high-pitched whistle made when breathing)
