Why is it prescribed?
Fluzone® High-Dose Quadrivalent influenza is a vaccine used to prevent influenza in adults 65 years of age and older.
Each year, different strains of the influenza virus appear. Scientists try to predict which strains will be most likely for the coming year, and these strains are used to make up the year's influenza vaccine. Fluzone® High-Dose contains 2 influenza A strains and 2 influenza B strain. The vaccine only protects against the strains of flu virus used to prepare the vaccine.
Fluzone® High-Dose influenza vaccine contains a higher level of each of the included influenza strains than the standard influenza vaccines. Evidence has shown that Fluad® , Fluzone High-Dose® and Supemtek™ provide better protection against influenza in adults over 65 years of age.
It usually takes 2 to 4 weeks for the protection against these viruses to be effective, and the protection lasts for 6 to 12 months. Annual vaccination is necessary to make sure you are covered for the new virus strains that are expected each year.
The best time for vaccination is from mid-October, but anytime in the flu season (November to April) is appropriate.
Contrary to popular belief, influenza vaccine cannot cause the flu.
Fluzone® High-Dose may not work for everybody.

Fluzone® High-Dose Quadrivalent is only for use in adults 65 years of age and older.
The dose is 0.7 ml given as a single intramuscular injection.
The influenza vaccine causes the body to produce antibodies against the virus. This means that when your body is exposed to the influenza virus, your body is able to defend itself. The antibodies stop the attacking virus. Influenza viruses change all the time, so different vaccines are made every year.
