What is the Fluzone High-Dose vaccine?
The Fluzone High-Dose vaccine was designed especially for people ages 65 and older. It contains a higher dose of antigen than regular influenza shots, therefore offering more immunity.
Why is a higher dose vaccine needed for adults 65 and older?
Immune defenses become weaker with age, which places older people at greater risk of severe illness from influenza. Also, the body’s ability to have a good immune response after getting the vaccine weakens with age. A higher dose of antigen in the vaccine is supposed to give older people a better immune response, and therefore, better protection against flu.
Is the high-dose vaccine effective?
Data from clinical trials comparing the high-dose vaccine with the regular dose do indicate a stronger immune response. However, ongoing studies have yet to determine whether this leads to greater protection against flu-related illness.
