Primary Outcome Measures:
  • Immunological non-inferiority (GMT & seroconversion rates) of Fluarix vs Fluzone 21 days post-vaccination in adults (18 yrs)

Secondary Outcome Measures:
  • Non-inferiority of Fluarix vs Fluzone 21 days post-vacc in elderly (>65 yrs)
  • Immuno comparison of Fluarix vs Fluzone post-vacc in immunologically -competent, -compromised, overall, stratified by age
  • Safety comparison (sol local, general & unsol AEs, SAEs)

Enrollment: 1847
Study Start Date: October 2005
Study Completion Date: May 2006
Primary Completion Date: May 2006 (Final data collection date for primary outcome measure)
Detailed Description:
  • Experimental design: multi-center, randomized (1:1), observer-blind, active-controlled study in 2 parallel groups with approximately:
  • Study vaccine: full dose of Fluarix by IM administration.
  • Control vaccine: full dose of Fluzone by IM administration.
  • Two scheduled visits per subject at days 0 (visit 1) and 21(visit 2) with blood sample collected at each visit to evaluate the immune response. There will be a final contact with each subject 6 months after vaccination for safety follow up and study conclusion.
  • Vaccination schedule: one IM injection at day 0.
  • Type of study: Self contained.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • All adults 18 years and older.
  • Subjects who the investigator believes can and will comply with the requirements of the protocol (e.g., return for follow-up visit and completion of the diary cards) should be enrolled in the study.
  • Written informed consent obtained from the subject.
  • If the subject is female, she must be of non-childbearing potential, i.e. either surgically sterilized or one year post-menopausal; or, if of childbearing potential, she must be abstinent or have used adequate contraceptive precautions .

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.
  • Has received any other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to enrollment in this study.
  • History of hypersensitivity to a previous dose of influenza vaccine.
  • History of allergy or reactions likely to be exacerbated by any component of the vaccine(s) including egg, chicken protein, gelatine, formaldehyde, gentamicin sulphate, thimerosal or sodium deoxycholate.
  • Acute disease at the time of enrollment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection with or without low-grade febrile illness, i.e. Oral temperature <37.5°C (99.5°F) / Axillary temperature <37.5°C (99.5°F)).
  • History of Guillain Barré syndrome within 6 weeks of prior receipt of inactivated influenza virus vaccine.
  • Pregnancy and lactating females.
