Study Overview
=================
Brief Summary
-----------------
This study is in support of the annual application for the variation of the vaccine strains for a marketing authorization. Objectives: To evaluate the compliance, in terms of immunogenicity, of the influenza vaccine (split virion, inactivated) Northern Hemisphere (NH) 2009-2010 formulation in two adult groups, aged 18 to 60 years and aged 61 years or older. To describe the safety of the influenza vaccine (split virion, inactivated) NH 2009-2010 formulation in both adult groups.
