Study to Evaluate the Safety and Immunogenicity of GlaxoSmithKline Biologicals' Influenza Vaccine in Elderly People

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.

  4. Duration of Solicited General AEs

    Time frame: Day 0-6

    Duration was defined as number of days with any grade of general symptoms.

  5. Number of Subjects Reporting Any, Grade 3 and Related Unsolicited AEs

    Time frame: 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.

  6. Number of Subjects Reporting Any, Grade 3 and Related AEs With a Medically Attended Visit

    Time frame: 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.

  7. Number of Subjects Reporting AEs of Specific Interest (AESI)

    Time frame: 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.

    Time frame: 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.
