• An acute evolving neurological disorder or Guillain Barré Syndrome within 42 days of receipt of prior seasonal or pandemic influenza vaccine.
• Administration of an inactive vaccine within 14 days or of a live attenuated vaccine within 30 days before the first dose of study vaccine/placebo.
• Planned administration of any vaccine other than the study vaccine/placebo before blood sampling at the Day 42 visit.
• Previous administration of any H7 vaccine or physician-confirmed H7 disease.
• Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine/placebo, or planned use during the study period.
