Read this carefully before you are given FLUCELVAX® QUAD. This leaflet is a summary and will not tell you everything about this vaccine. Talk to your healthcare professional about your medical condition and treatment and ask if there is any new information about FLUCELVAX® QUAD.

What is FLUCELVAX® QUAD used for?

FLUCELVAX® QUAD is used in adults and children 9 years and older to prevent influenza, often called "the flu."

Influenza is caused by infection with specific influenza viruses. New types of influenza viruses can appear each year. FLUCELVAX® QUAD vaccine contains fragments of four different types of influenza virus. Each year the World Health Organization decides which four types of viruses are most suitable to include in the vaccine.

You cannot catch influenza from the vaccine, as the virus in the vaccine has been killed and split into small non-infectious particles.

The National Advisory Committee on Immunization (NACI) encourages annual influenza vaccination for all Canadians who are able to have the vaccine.

Vaccination against influenza is recommended every year, for anyone wanting to lower their chance of catching influenza. FLUCELVAX® QUAD has been used by many people to lower their risk of catching the flu.

How does FLUCELVAX® QUAD work?

FLUCELVAX® QUAD vaccine works by helping your body to protect itself against infection by the types of influenza viruses that are in the vaccine. The vaccine stimulates the body to make substances called antibodies. Antibodies fight the influenza virus. If you have been vaccinated, when you come into contact with the influenza viruses in the vaccine, your body is usually able quickly to destroy the virus, which may prevent you from getting influenza.

Your body takes a few weeks after vaccination to fully develop effective protection against the influenza virus.

Protection against influenza requires one dose of FLUCELVAX® QUAD vaccine.

As with all vaccines, 100% protection cannot be guaranteed.

FLUCELVAX® QUAD is not made using eggs; therefore, there are no egg proteins in the vaccine.

The syringe and vial components do not contain latex. FLUCELVAX® QUAD is considered safe for use in persons with latex allergies.

FLUCELVAX® QUAD pre-filled syringes contain no preservative or antibiotics. FLUCELVAX® QUAD multi-dose vial formulation contains a preservative, but does not contain any antibiotics.
