SupemtekTM is a vaccine used to prevent influenza and may be given to adults 18 years and older.
Annual influenza vaccination is recommended because immunity during the year after vaccination declines and because circulating strains of influenza virus change from year to year.
SupemtekTM causes your body to produce its own natural protection against influenza virus. After you receive the vaccine, your body begins to make substances called antibodies against the strains of virus that are in the vaccine.
Antibodies help your body to fight disease and are effective for the duration of the flu season. When you are exposed to the virus, the antibodies will help to keep you from getting sick. If you do get the flu, you may not be as sick.
Most flu vaccines are made by using an egg-based manufacturing process that involves growing the virus in chicken eggs.
Recombinant vaccine production, however, doesn't use chicken eggs in the process.
The recombinant method uses proteins isolated from the flu vaccine virus that are combined with a portion of another virus that grows in insect cells. The resulting "recombinant" vaccine virus is then mixed with insect cells and allowed to replicate. The flu surface protein called hemagglutinin (HA) is then harvested from these cells and purified.
SupemtekTM contains 45 μg each of the four specific virus proteins (HAs) from strains chosen annually for the Northern hemisphere by the World Health Organization (WHO).
The proteins in SupemtekTM have the same structure as the ones from the four flu strains the WHO has recommended for inclusion in the Northern hemisphere’s seasonal flu vaccine.

Use the following questions to find out more from your healthcare practitioner (HCP):
What’s the difference between the SupemtekTM vaccine and flu vaccines made without recombinant technology?
Do I have any pre-existing health conditions that could make the flu more dangerous for me? If so, what are the other risks if I get infected with the flu?
What are my options to help prevent the flu as a patient with chronic health conditions?
Looking for other flu vaccine options?
Indication and safety information:
SupemtekTM is a vaccine used to prevent influenza. This vaccine may be given to adults 18 years and older. Annual influenza vaccination is recommended because immunity during the year after vaccination declines and because circulating strains of influenza virus change from year to year. People who have a known severe allergy to any ingredient in SupemtekTM or who have had a severe allergic reaction after receiving a vaccine that contained similar ingredients should not use SupemtekTM. SupemtekTM will only protect against the strains of influenza virus contained in the vaccine or those that are closely related. SupemtekTM will not protect against any other strains of influenza virus. SupemtekTM is not indicated for the prevention of hospitalization or death or to reduce the risk of complications after the onset of disease. As with all vaccines, SupemtekTM does not protect 100% of people immunized. The most common side effects are local pain and tenderness, fatigue, headache and muscle and joint pain. Talk to your doctor, nurse or pharmacist to see if this vaccine is right for you. For more information, visit www.sanofi.ca.
