 severity on the scheduled date of first vaccination.

 -  Diagnosed with cancer, or treatment for cancer within 3 years.

 -  Any confirmed or suspected immunosuppressive or immunodeficient condition including
 history of human immunodeficiency virus (HIV) infection.

 -  Chronic administration of immunosuppressants or other immune modifying drugs within 6
 months of study enrolment or planned administration during the study period.

 -  Receipt of any immunoglobulins and/or any blood products within 3 months of study
 enrolment or planned administration of any of these products during the study period.

 -  Any significant disorder of coagulation or treatment with warfarin derivatives or
 heparin.

 -  An acute evolving neurological disorder or history of Guillain-Barré syndrome.

 -  Administration of any vaccines within 30 days before vaccination or planned
 administration within the first vaccination up to blood sampling at Day 42 and within
 30 days prior to blood sampling at Day 182, with the exception of seasonal influenza
 vaccine.

 -  Administration of any seasonal influenza vaccine within 14 days before vaccination on
 Day 0, or planned administration within the first vaccination up to blood sampling at
 Day 42 and within 14 days prior to blood sampling at Day 182.

 -  Any known or suspected allergy to any constituent of influenza vaccines or component
 used in the manufacturing process of the study vaccine; a history of anaphylactic-type
