As people age, they become more susceptible to flu-related complications because the immune system weakens as people age. As a result, seniors are less responsive to the standard flu vaccine.
Fluzone High-Dose contains 4 times the antigen of a standard flu vaccine so it can better protect seniors 65 years and older. In one study it was found to be 24% more effective than the regular flu vaccine.
The vaccine is available at some pharmacies, and at the VCH Travel Clinic for $75.
