About Fluzone® High-Dose
A higher dose specifically formulated for adults 65+
As you age, your immune system weakens. Which means your antibody response to vaccines isn’t as high as it used to be. Fluzone® High-Dose Quadrivalent vaccine is made for people 65+
The Fluzone® High-Dose Quadrivalent vaccine provides 4x the amount of antigens (killed virus particles) for each influenza strain contained in the vaccine compared to standard-dose influenza vaccines. The higher dose is intended to give people 65 years and older a better immune response and, therefore, better protection against the flu.

Indication and safety information:
Fluzone® High-Dose Quadrivalent is a vaccine used to prevent influenza in adults 65 years of age and older. Influenza (or flu) is an infection caused by the influenza virus. Annual vaccination using the current vaccine is recommended for prevention against influenza as immunity declines in the year following vaccination and because circulating strains of influenza virus change from year to year. Persons with a history of severe allergic reaction to eggs or egg products or any component of Fluzone® High-Dose Quadrivalent should not receive the vaccine.
Fluzone® High-Dose Quadrivalent will only protect against the strains of influenza virus contained in the vaccine or those that are closely related. Fluzone® High-Dose Quadrivalent will not protect against any other strains of influenza virus. Fluzone® High-Dose Quadrivalent 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, Fluzone® High-Dose Quadrivalent does not protect 100% of people immunized. The most common side effects are pain at the injection site, muscle ache. Allergic reactions can occur. Contact your healthcare provider to see if this vaccine is right for you. For more information, visit www.sanofi.ca.
