简要总结
The purpose of the study is to evaluate the safety of GSK Biologicals' influenza vaccine. Elderly subjects were randomized in the primary study (NCT00760617) and will now receive the same vaccine for the third time. For this study the masking is "observer-blind" for elderly subjects and "open" for young adult subjects.

- •Written informed consent obtained from the subject.
- •Free of an acute aggravation of the health status as established by clinical evaluation before entering into the study.
- •Female subjects of non-childbearing potential may be enrolled in the study.
- •Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause.
- •Female subjects of childbearing potential may be enrolled in the study if the subject:
- •has practiced adequate contraception for 30 days prior to vaccination, and
- •has a negative pregnancy test on the day of vaccination, and
- •has agreed to continue adequate contraception for 2 months after the vaccination.
排除标准
- •The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study:
- •Use of any investigational or non-registered product other than the study vaccine(s) within 30 days prior to vaccination, or planned use 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 an influenza vaccine other than the study vaccines or of a vaccine not foreseen in the study protocol during the entire study period.
- •Vaccination against influenza since January 2009 with a seasonal influenza vaccine.
- •Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the administration of the study vaccine.
- •Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
- •History of hypersensivity to a previous dose of influenza vaccine.
- •History of allergy or reactions likely to be exacerbated by any component of the vaccine(s).
- •Acute clinically significant pulmonary, cardiovascular, hepatic, renal, neurological and psychiatric disorders, as determined by clinical evaluation or pre-existing laboratory screening tests.
- •Acute disease and/or fever at the time of enrolment.
- •Fever is defined as temperature >=37.5°C on oral setting.
- •Subjects with a minor illness without fever may be enrolled at the discretion of the investigator.
- •Administration of immunoglobulins and/or any blood products within the three months preceding the administration of the study vaccine or planned administration during the study.
- •Any medical conditions in which IM injections are contraindicated
- •Pregnant or lactating female.
- •Female planning to become pregnant or planning to discontinue contraceptive precautions.

结局指标
主要结局
Duration of Solicited Local AEs
时间窗: Day 0-6
Duration was defined as number of days with any grade of local symptoms.
Number of Subjects Reporting Any, Grade 3 and Related Solicited General AEs
时间窗: Day 0-6
Any fever was defined as oral temperature ≥ 38.0 degree centigrade (°C), grade 3 fever was oral temperature ≥ 39.0°C-≤ 40.0°C. For other symptoms, any was defined as occurrence of any general symptom regardless of intensity grade, grade 3 was defined as general symptom that prevented normal activity and related was general symptom assessed by the investigator as causally related to the study vaccination.
Number of Subjects Reporting AEs of Specific Interest (AESI)
时间窗: Day 0-179
AESI for safety monitoring are a subset of AEs that include both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology. Any was defined as occurrence of any symptom regardless of intensity grade, grade 3 was defined as symptom that prevented normal activity and related was general symptom assessed by the investigator as causally related to the study vaccination.
Number of Subjects Reporting Any and Grade 3 Solicited Local Adverse Events (AEs)
时间窗: Day 0-6
Grade 3 ecchymosis, redness and swelling was ≥ 100 millimeter (mm) and grade 3 pain was considerable pain at rest, that prevented normal everyday activities.
Number of Subjects Reporting Any, Grade 3 and Related AEs With a Medically Attended Visit
时间窗: Day 0-179
For each solicited and unsolicited AE the subject experienced, the subject was asked if they had received medical attention defined as hospitalization, an emergency room visit or a visit to or from medical personnel (medical doctor) for any reason. Any was defined as occurrence of any symptom regardless of intensity grade, grade 3 was defined as symptom that prevented normal activity and related was general symptom assessed by the investigator as causally related to the study vaccination.
Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs) up to Day 180
时间窗: Up to Day 180
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 was defined as occurrence of any symptom regardless of intensity grade and related was event assessed by the investigator as causally related to the study vaccination.
Duration of Solicited General AEs
时间窗: Day 0-6
Duration was defined as number of days with any grade of general symptoms.
Number of Subjects Reporting Any, Grade 3 and Related Unsolicited AEs
时间窗: Day 0-20
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 was defined as occurrence of any unsolicited symptom regardless of intensity grade, grade 3 was unsolicited symptom that prevented normal activity and related was event assessed by the investigator as causally related to the study vaccination.
