When This Medicine Should Not Be Used
You should not receive this vaccine if you have had an allergic reaction to influenza vaccine (flu shot). Tell your caregiver if you have ever had a reaction to any vaccine. Sometimes, certain people can be given only certain brands of this medicine. Make sure your doctor knows if you are allergic to kanamycin, neomycin, or polymyxin or to eggs or chicken.
How to Use This Medicine
- The vaccine is given as a shot into a muscle or into your skin, usually in the shoulder area. The shot could be given in the thigh for babies and young children.
- A nurse or other health provider will give you this medicine.
- A child who is younger than 9 years and who has not had a flu shot before may need 2 shots. The second shot should be given about 1 month after the first shot. It is usually best for the child to have received both shots before December.
- You need to get the flu vaccine every year to protect you from the flu.

If a dose is missed:

- If your child needs a second dose of the vaccine, it is very important for him to receive the second dose on schedule. If you must cancel the appointment, make another appointment as soon as possible.
Drugs and Foods to Avoid
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
- Make sure your doctor knows if you are using a medicine or treatment that weakens your immune system, such as a steroid, radiation, or cancer treatment. This vaccine may not work as well if you are also using these medicines. Your doctor may still want you to get the vaccine because it can give you some protection.
