Inclusion Criteria: - A male or female aged 18-60 years old at the time of vaccination, who previously participated in 108656 clinical trial. - Subjects who the investigator believes that they can and will comply with the requirements of the protocol. - Written informed consent obtained from the subject. - Free of obvious health problems as established by medical history and clinical examination before entering into the study. - If the subject is female, she must be of non-childbearing potential or, if of childbearing potential, she must be abstinent or have used adequate contraceptive precautions for 30 days prior to vaccination, have a negative pregnancy test and must agree to continue such precautions for two months after completion of the vaccination series. Exclusion Criteria: - Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the administration of the study vaccine, or planned use during the study period. - Planned administration of an influenza vaccine other than the study vaccines during the entire study period - Previous vaccination against influenza since January 2007. - Acute or chronic clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests. - Chronic administration of immunosuppressants or other immune-modifying drugs within three months prior to the first vaccine dose. - Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination - Administration of immunoglobulins and/or any blood products within three months preceding the dose of study vaccine or planned administration during the study period. - History of hypersensitivity to a previous dose of influenza vaccine. - History of confirmed influenza infection within the last 12 months. - Pregnancy. - History of allergy or reactions likely to be exacerbated by any component of the vaccine(s) - Acute disease at the time of enrolment. |

Primary | Number of Subjects With Any, Grade 3 and Related Solicited Local Symptoms | Assessed solicited local symptoms were ecchymosis, pain, redness and swelling at injection site. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal everyday activity. Grade 3 redness/swelling/ecchymosis = redness/swelling/ecchymosis spreading beyond 50 millimeters (mm) of the injection site. All solicited local symptoms assessed were considered by the investigator as related to study vaccination. | During a 7-day (Days 0-6) follow-up period after re-vaccination | |
Primary | Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms. | Assessed solicited general symptoms were arthralgia, fatigue, fever [oral temperature equal to or above = 37.5 degrees Celsius (°C)], headache, myalgia, nausea and shivering. Any = incidence of a particular symptom regardless of grade intensity or relationship with the study vaccination. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0°C. Related = symptom considered by the investigator to have a causal relationship to study vaccination. | During a 7-day (Days 0-6) follow-up after re-vaccination | |
Primary | Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs) | Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 = unsolicited AE that prevented normal activity. Related = unsolicited AE assessed by the investigator as causally related to the study vaccination. | During a 30-day (Days 0-29) follow-up period after re-vaccination | |
Primary | Number of Subjects With Any and Related Serious Adverse Events (SAEs) | Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Related = SAE assessed by the investigator as causally related to the study vaccination. | During the entire study period (Days 0-30) | |
Secondary | Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease. | Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). The seropositivity cut-off assay was 1:10. | At Days 0 and 21 | |
Secondary | Number of Seroconverted Subjects Against 3 Strains of Influenza Disease. | A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer <1:10 and a post-vaccination titer =1:40 or a pre-vaccination titer =1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). | At Day 21 | |
Secondary | Number of Seroprotected Subjects Against 3 Strains of Influenza Disease. | A seroprotected subject was defined as a vaccinated subject who had a serum HI titer = 1:40. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). | At Day 0 and 21 | |
Secondary | Seroconversion Factor for HI Antibodies Against 3 Strains of Influenza Disease. | The seroconversion factor (SCF) was defined as the fold increase in serum Hemagglutination Inhibition (HI) geometric mean titers (GMTs) post vaccination compared to Day 0. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). | At Day 21 |
