We are currently looking for 155 healthy volunteers to participate in a trial with study medication for the treatment of Influenza A (flu). The study consists of 7 groups of 20 people each. You can subscribe for multiple panels, but you can only participate in 1. When registering, please indicate all possible groups which you are available for.

The study will take about 8 months to complete. The study consists of:

  • Prescreening (VS1): Information about the study + blood sample (not fasted)
  • Screening visit (VS2): General examination (fasted)
  • Vaccination visit: Ambulant visit (± 2 hours after vaccination)
  • 3 retours (short visits to our unit)
  • 2 telephone follow-ups

During this study the Influenza A flu virus will be given intranasal (through the nose) with the aid of a nasal spray. During your stay you will stay in quarantine (closed ward). Because of this you may NOT receive any visits during this stay.
