Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • A male or female age 60 years or older at the time of the revaccination, who previously participated in 107192 & 107214 clinical trials.
  • Subjects who the investigator believes can and will comply with the requirements of the protocol
  • Written informed consent obtained from the subject.
  • Free of an acute aggravation of the health status as established by clinical examination before entering into the study.

Exclusion criteria

  • Use of any investigational or non-registered product (drug or vaccine) within 30 days preceding the administration of the study vaccine, or planned use during the study period.
  • Acute clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
  • Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within 3 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 the 3 months preceding the first dose of study vaccine or planned administration during the study period.
  • Administration of other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to enrolment in this study. Planned administration of a vaccine not foreseen by the study protocol up to 30 days after vaccination.
  • History of hypersensitivity to a previous dose of influenza vaccine.
  • History of confirmed influenza infection within the last 12 months.
  • History of allergy or reactions likely to be exacerbated by any component of the vaccine(s)
  • Acute disease at the time of enrolment.

Primary outcomes

  1. Number of Subjects With Any and Grade 3 Solicited Local Symptoms.

    Time frame: During the 7-day (Days 0-6) post-vaccination period

    Assessed solicited local symptoms were ecchymosis, pain, redness and swelling. Any = Incidence of a particular solicited local symptom regardless of intensity grade. Grade 3 pain = Pain that prevented normal everyday activity. Grade 3 redness/swelling/ecchymosis = Redness/swelling/ecchymosis above 50 millimeters (mm).

  2. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms.

    Time frame: During the 7-day (Days 0-6) post-vaccination period

    Assessed solicited general symptoms were arthralgia, fatigue, fever, headache, muscle aches and shivering. Any = Incidence of a particular solicited general symptom regardless of intensity grade or relationship with the study vaccination. Any Fever = Axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C). Grade 3 symptom = Symptom that prevented normal activity. Grade 3 fever = Axillary temperature > 39.0°C. Related = Symptom considered by the investigator to have a causal relationship to study vaccination.

  3. Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs).

    Time frame: During the 30-day (Days 0-29) post vaccination period

    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 vaccination.

  4. Number of Subjects With Any and Related Serious Adverse Events (SAEs).

    Time frame: During the entire study period (from Day 0 to Day 29)

    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. Any SAE = Occurrence of any SAE regardless of intensity grade or relation to vaccination Related = SAE considered by the investigator to have a causal relationship to study vaccination.

Secondary outcomes

  1. Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease.

    Time frame: At Day 0 and Day 21

    Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia. The seropositivity cut-off assay was 1:10.

  2. Number of Seroconverted Subjects Against 3 Strains of Influenza Disease.

    Time frame: At Day 21

    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/New Caledonia, A/Wisconsin and B/Malaysia.

  3. Number of Seroprotected Subjects Against 3 Strains of Influenza Disease.

    Time frame: At Day 0 and Day 21

    A seroprotected subject was defined as a vaccinated subject who had a serum HI titer ≥ 1:40. The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia.

  4. Seroconversion Factor for Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease.

    Time frame: At Day 21

    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/New Caledonia, A/Wisconsin and B/Malaysia.
