* Children, male or female between, and including, 6 and 35 months of age at the time of the first vaccination.
* Written informed consent obtained from the parent(s)/LAR(s) of the subject.
* Healthy subjects as established by medical history and clinical examination before entering into the study.
* Age appropriate scheduled childhood vaccinations completed to the best of parent(s)/LAR(s) knowledge.

Exclusion Criteria:

The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study:

* Child in care
* Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.
* Prior receipt of any influenza vaccination (seasonal or pandemic) or planned administration during the study period.
* Planned administration of any vaccine 30 days prior and 30 days after any study vaccine administration.
* Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. For corticosteroids, this will mean prednisone \>0.5 mg/kg of body weight, or equivalent. Inhaled and topical steroids are allowed.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
* A family history of congenital or hereditary immunodeficiency.
* Any known or suspected allergy to any constituent of influenza or routine paediatric vaccines, a history of severe adverse reaction to any previous vaccination; or a history of anaphylactic-type reaction to consumption of egg proteins.
* History of any neurological disorders or seizures (including febrile convulsion).
* Acute or chronic, clinically-significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by medical history or physical examination.
* Acute disease and/or fever at the time of enrolment:

  * Fever is defined as temperature \>= 37.5°C on oral, axillary or tympanic setting, or \>=38.0°C on rectal setting.
  * Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever might be enrolled at the discretion of the investigator.
* Administration of immunoglobulins and/or any blood products within the 3 month preceding the first dose of study vaccine or planned administration during the study period.
* Any condition which, in the opinion of the investigator, render the subject unfit for participation in the study.
