Name Time Method Main Objective: Safety Objective<br>To compare the safety of a single intramuscular (IM) dose of the cell-derived influenza subunit vaccine (Optaflu®) with that of the egg-derived influenza subunit vaccine (Agrippal®) in adult and elderly subjects with and without underlying conditions.<br><br>;Secondary Objective: Immunogenicity Objective<br>To evaluate the immunogenicity of Optaflu® and Agrippal® for each influenza vaccine strain, as measured by hemagglutination inhibition (HI) test 21 days after vaccination in a subset of adult and elderly subjects with underlying medical conditions.<br>;Primary end point(s): see E.2.1 an E.2.2
