To describe any degree of preference for the route of administration of Fluzone influenza vaccine, ID versus IM, in healthy adult subjects 18-49 years of age.
To collect safety data, injection site reactions, and systemic reactions, through Day 7 post-vaccination; SAEs through day 28 post-vaccination
Primary Outcome Measures:
- Preference for route of administration on Day 0 immediately after vaccination, and on Days 3 and 7 [ Time Frame: 7 Days post-vaccination ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- To observe solicited injection site reactions, solicited systemic reactions, and SAEs. [ Time Frame: 28 Days post-vaccination ] [ Designated as safety issue: Yes ]

The purpose of this clinical trial is to determine, in a relatively small sample of persons 18-49 years of age, if there is a preference trend for a particular route of administration, ID vs IM, when receiving a seasonal influenza vaccine. Uptake of influenza vaccine is disappointingly low in this age group, and there is the perception that aversion to IM injection plays a role in vaccination avoidance. The BD Micro-Injection System to be used in this study may offer a more acceptable alternative to the standard IM injection for influenza immunization and thereby promote wider acceptance of influenza vaccination.
