Primary Outcome Measures:
  • Humoral immune response in terms of H1N1 haemagglutination inhibition (HI) antibodies [ Time Frame: Day 0, Day 21, Day 42 and Month 6+7 Days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Humoral immune response in terms of H1N1 HI antibodies [ Time Frame: Day 0, 21, 42, Month 6, Month 6+7 Days, Month 12 and Month 18 ] [ Designated as safety issue: No ]
  • Humoral immune response in terms of neutralizing antibodies (in a subset of subjects) [ Time Frame: Day 0, 21, 42, Month 6, Month 6+7 Days, Month 12 and Month 18 ] [ Designated as safety issue: No ]
  • Occurrence of local and general symptoms [ Time Frame: During a 7-day follow-up period after each vaccination ] [ Designated as safety issue: No ]
  • Occurrence of unsolicited symptoms [ Time Frame: During a 21-day follow-up period after the first vaccination, during a 62-day follow-up period after the second vaccination, and during a 30 day follow up period after the booster vaccination ] [ Designated as safety issue: No ]
  • Occurrence of adverse events of specific interest / potential immune-mediated disorders, of serious adverse events, and of medically attended visits [ Time Frame: From the beginning up to the study end (i.e. Day 0 up to Month 12) ] [ Designated as safety issue: No ]
  • Safety evaluation in terms of biochemical parameters [ Time Frame: Day 0, 21, 42, Month 6 and Month 6 + 7 Days ] [ Designated as safety issue: No ]

Inclusion Criteria:

  • Subjects who the investigator believes that their parent(s)/Legally Acceptable Representative(s) (LAR) can and will comply with the requirements of the protocol.
  • Children, male or female, aged between 3 and 17 years at the time of the first study vaccination.
  • Written informed consent obtained from the subject parent(s) or LAR(s) of the subject. Assent obtained from the subject when applicable.
  • Healthy children as established by medical history and clinical examination when entering into the study.
  • Parent/LAR with access to a consistent means of telephone contact, land line or mobile, but NOT a pay phone or other multiple-user.

Exclusion Criteria:

  • Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of the study vaccine or planned use during the study period.
  • Clinically or virologically confirmed influenza infection within six months preceding the study start.
  • Planned administration of any vaccine 30 days prior and 30 days after any study vaccine administration.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within three months prior to enrolment in this study or planned administration during the study period.
  • Acute disease and/or fever at the time of enrolment
  • Any confirmed or suspected immunosuppressive or immunodeficient condition based on medical history and physical examination.
  • Acute or chronic, clinically-significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by medical history and physical examination.
  • Previous administration of any H1N1 A/California-like vaccine.
  • Administration of immunoglobulins and/or any blood products within the three months prior to the enrolment in this study, or planned during the study.
  • If the subject is female and if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for two months after completion of the vaccination series.
  • Any known or suspected allergy to any constituent of influenza vaccines;a history of anaphylactic-type reaction to any constituent of influenza vaccines; or a history of severe adverse reaction to a previous influenza vaccine.
