Brief Summary
The purpose of this study is to generate data on immunogenicity and safety of the monovalent H1N1 vaccine in support of the development and registration. Primary objectives:
- To describe the immune response to vaccines 21 days after each vaccination in all participants.
- To describe the antibody persistence eight months after the first vaccine administration using HAI method, in a subset of participants who received two injections.
- To describe the immune response against the A/H1N1 strain using HAI method 21 days after a vaccination with the 2010-2011 NH seasonal TIV administered approximately 13 months after the first vaccination in the subset of participants who received two injections.
- To describe the safety profile of each vaccine in all participants.

Outcome Measures
Primary Outcomes (2)
Immunogenicity: To provide information concerning the immunogenicity of Swine A/H1N1 influenza vaccines
21 days post vaccination
Safety: To provide information concerning the safety (in terms of solicited injection site and systemic reactions and unsolicited adverse events) of Swine A/H1N1 influenza vaccines.
0-7 days post-vaccination and entire study duration
Study Arms (3)
A/H1N1 Vaccine Group 1
EXPERIMENTALAll participants will receive A/H1N1 Influenza vaccine formulation 1 at Visits 1 and 2; a subset will receive a trivalent influenza vaccine (TIV) at Month 13 (antibody persistence subset).
A/H1N1 Vaccine Group 2
EXPERIMENTALAll participants will receive A/H1N1 Influenza vaccine formulation 2 at Visits 1 and 2; a subset will receive a trivalent influenza vaccine (TIV) at Month 13 (antibody persistence subset).
A/H1N1 Vaccine Group 3
EXPERIMENTALParticipants will receive A/H1N1 Influenza vaccine formulation 3
Interventions

0.5 mL, Intramuscular on Day 0 and Day 21 (all participants); and 0.5 mL of a trivalent influenza vaccine (TIV) at Month 13 (antibody persistence subset).
Eligibility Criteria
You may qualify if:
- All subjects:
- Provision of Informed Consent Form signed by the subject's parent(s)/legal representative (and by an independent witness if required by local regulations). In addition, provision of Assent Form signed by subjects aged 8 to 12 years, and of Informed Consent Form signed by subjects \>12 years.
- Subject and parent/guardian are able to attend all scheduled visits and to comply with all trial procedures
- Subjects aged 12 to 17 years:
- For a female of childbearing potential, use of an effective method of contraception or abstinence for at least 4 weeks prior to the first vaccination, until at least 4 weeks after the last vaccination.
- Subjects aged 3 to 11 years:
- At Visit 05 (Month 8), for antibody persistence assessment:
- Having received two injections of the 15 µg HA vaccine (Group 1) or of the 3.8 µg HA + AF03 vaccine (Group 2)
- Addendum 1 to Informed Consent Form has been signed by the subject's parent(s)/guardian(s) (and by an independent witness if required by local regulations). In addition, provision of addendum 1 to Assent Form signed by subjects aged 6 to 11 years, and of addendum 1 to Informed Consent Form signed by subjects ≥ 12 years.
- At Visit 06, for participants eligible for the Antibody persistence evaluation who will receive the 2010-2011 Northern Hemisphere (NH) seasonal Trivalent Influenza Vaccine:
- Addendum 2 to Informed Consent Form has been signed by the subject and/or subject's parent(s)/guardian(s) (and by an independent witness if required by local regulations). In addition, provision of addendum 2 to Assent Form signed by subjects aged 6 to 11 years, and of addendum 2 to Informed Consent Form signed by subjects ≥ 12 years.
You may not qualify if:
- All subjects:
- Participation in another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the first trial vaccination
- Planned participation in another clinical trial during the present trial period
- Receipt of any vaccine in the 4 weeks preceding the trial vaccinations
- Planned receipt of any vaccine prior to the Day 42 blood sample
- Receipt of blood or blood-derived products in the past 3 months which might interfere with the assessment of immune response
- Known or suspected congenital or acquired immunodeficiency, immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months, or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
- Seropositivity for Human Immunodeficiency Virus (HIV), Hepatitis B antigen, or Hepatitis C as reported by parents/legal representative
- Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine(s) used in the trial or to a vaccine containing any of the same substances
- Thrombocytopenia contraindicating intramuscular (IM) vaccination as reported by parents/legal representative
- Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
- Chronic illness that in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion
- Employee of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, as well as family members of the employees or the Investigator
- Previous participation in a trial investigating a vaccine with the swine-origin A/H1N1 influenza strain
- Confirmed infection with the swine-origin A/H1N1 influenza strain (different from the seasonal strain) in 2009
