Title: Evaluate the Reactogenicity & Immunogenicity of 1 or 2 Booster Administrations of an Influenza Pandemic Candidate Vaccine (GSK1562902A) in Primed Adults Aged Between 19 & 61 Years
Brief Summary: The present study is designed to evaluate the reactogenicity and immunogenicity of one or two booster administrations of an influenza pandemic candidate vaccine (GSK1562902A) in adults aged between 19 and 61 years, previously vaccinated with 2 doses of a pandemic candidate vaccine. Fifty new subjects who did not participate in a primary study (106750, NCT00309634) will be recruited. This protocol posting deals with objectives \& outcome measures of the booster phase. The objectives \& outcome measures of the primary phase are presented in a separate protocol posting (NCT00309634)

* Comprehension of the study requirements, expressed availability for the required study period, and ability to attend scheduled visits.

Exclusion Criteria:

Immunization on an emergency basis with Tetanus Toxoid Adsorbed for adult use (Td or Tdap) up to 8 days before or at least 8 days after a dose of study vaccine will be allowed. Administration of study vaccine injection can be delayed if a nonstudy vaccine has been administered and will be given as soon as acceptable, as described above, provided the vaccine is not administered within two weeks prior to study enrollment.
* History of anaphylactic type reaction to injected vaccines.

* Donation of blood or blood products within 8 weeks prior to vaccination or at any time during the study.
* Acute disease within 72 hours prior to vaccination, defined as the presence of a moderate or severe illness (as determined by the investigator through medical history and physical examination; for example, those requiring an absence from work) with or without fever, or a fever \>37.9ºC orally. Study vaccine can be administered to persons with a minor illness, such as diarrhea, or mild upper respiratory tract infection with or without low-grade febrile illness. Vaccination can be delayed until the subject has recovered.
* Any condition that, in the opinion of the investigator, might interfere with study objectives
