Fluzone High-Dose is a new influenza vaccine, manufactured by Sanofi Pasteur Inc., designed specifically for people 65 years and older.
Human immune defenses become weaker with age, which places older people at greater risk of severe illness from influenza. Also, aging decreases the body's ability to have a good immune response after getting the influenza vaccine. A higher dose of antigen in the vaccine is supposed to give older people a better immune response and therefore better protection against flu.
