About
The present study is designed to confirm the safety and immunogenicity of trivalent, surface antigen, inactivated influenza vaccine in 2 age cohorts: 18 to ≤60 years and ≥61 years and the antibody response to each influenza vaccine antigen, as measured by Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post immunization.
The vaccine composition will be based on the World Health Organization (WHO) recommended influenza strains for the 2013/2014 Northern Hemisphere vaccine.
The results of this study are intended to support the use of this vaccine in future influenza seasons if the recommended vaccine composition remains the same, in compliance with the requirements of the current European Union (EU) recommendations for clinical trials related to yearly licensing of influenza vaccines.

-
a known or suspected (or had a high risk of developing) impairment/alteration of immune function (excluding those normally associated with advanced age) resulting, for example, from:

was not able to comprehend and to follow all required study procedures for the whole period of the study;
-
Had a history or any illness that, in the opinion of the investigator, would pose additional risk to the subjects because of participation in the study;
-
Had the following within the past 6 months:
