What is influenza virus injectable vaccine (Afluria, Fluarix, FluLaval, Fluvirin, Fluvirin Preservative-Free, Fluzone, Fluzone Preservative-Free, Fluzone Preservative-Free Pediatric)?

Influenza virus (commonly known as "the flu") is a serious disease caused by a virus. Influenza virus can spread from one person to another through small droplets of saliva that are expelled into the air when an infected person coughs or sneezes. The virus can also be passed through contact with objects the infected person has touched, such as a door handle or other surfaces.

Influenza virus vaccine is used to prevent infection caused by influenza virus. The vaccine is redeveloped each year to contain specific strains of inactivated (killed) flu virus that are recommended by public health officials for that year.

The injectable influenza virus vaccine (flu shot) is a "killed virus" vaccine. Influenza virus vaccine is also available in a nasal spray form, which is a "live virus" vaccine.

Influenza virus vaccine works by exposing you to a small dose of the virus, which helps your body to develop immunity to the disease. Influenza virus vaccine will not treat an active infection that has already developed in the body.

Influenza virus vaccine is for use in adults and children who are at least 6 months old.

Becoming infected with influenza (commonly known as "the flu") is much more dangerous to your health than receiving the vaccine to protect against it. Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

Like any vaccine, influenza virus vaccine may not provide protection from disease in every person. This vaccine will not prevent illness caused by avian flu ("bird flu").

What are the possible side effects of influenza virus injectable vaccine?

Influenza virus injectable (killed virus) vaccine will not cause you to become ill with the flu virus that it contains. However, you may have flu-like symptoms at any time during flu season that may be caused by other strains of influenza virus.

You should not receive a booster vaccine if you had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects you have after receiving this vaccine. If you ever have to receive another influenza virus vaccine in the future, you will need to tell the doctor if the first shot caused any side effects.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any of these serious side effects:

• severe weakness or unusual feeling in your arms and legs (may occur 2 to 4 weeks after you receive the vaccine);
• high fever; or
• unusual bleeding.

Less serious side effects may include:

• low fever, chills;
• redness, bruising, pain, swelling, or a lump where the vaccine was injected;
• headache, tired feeling; or
• joint or muscle pain.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.
