Brief Summary:
The aim of this study is to determine the efficacy of Fluzone High Dose vaccine and that of Fluzone® vaccine in the elderly.
Primary objective:
To measure the efficacy of the vaccine, defined as the prevention of laboratory-confirmed influenza caused by viral types/subtypes that are antigenically similar to those contained in the respective annual vaccine formulations.
Secondary objectives:
* To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, with respect to laboratory-confirmed influenza illness caused by any type or subtype of influenza virus.
* To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, in preventing culture-confirmed influenza illness caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations.

Detailed Description:
The occurrence of influenza-like illness (ILI) will be determined in elderly participants vaccinated with either Fluzone High Dose or Fluzone® vaccine.
The presence of influenza virus in the respiratory tract of vaccinated individuals with ILI will be confirmed by two methods.
