Immunogenicity and Safety of a Vaccine Against Influenza (2010-2011 Northern Hemisphere Season, Intradermal Route)

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the new formulation of the influenza vaccine for the 2010-2011 Northern Hemisphere (NH) season in terms of immunogenicity and safety in the corresponding population and to check its compliance with the Committee for Proprietary Medicinal Products (CPMP) Note for Guidance (NfG) CPMP/BWP/214/96 Objectives: To evaluate compliance, in terms of immunogenicity, of the corresponding strength of the intradermal (ID) influenza vaccine NH 2010-2011 formulation with the requirements of the CPMP NfG CPMP/BWP/214/96. To describe the safety of the corresponding strength of the ID influenza vaccine, NH 2010-2011 formulation.

Detailed Description
-----------------
Each participant will receive a dose of their assigned vaccine on Day 0 and will be followed up for 21 days post-vaccination.
