About this trial

This is an interventional prevention trial for H5N1 Influenza focused on measuring Prophylaxis of influenza infection caused by a pandemic influenza virus (H5N1)

Eligibility Criteria

18 Years - 59 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Subject is 18 to 59 years old at the time of screening
  • Subject is generally healthy, as determined by the investigator´s clinical judgement through collection of medical history and performance of a physical examination
  • Subject is physically and mentally capable of participating in the study and willing to adhere to study procedures to include completion of all elements of the study diary
  • If female of childbearing potential, subject presents with a negative urine pregnancy test result within 24 hours prior ot the scheduled first vaccination and agrees to employ adequate birth control measures for the duration of the study

Exclusion Criteria:

  • Subject has a history of infectin with H5N1 virus or a history of vaccination with an H5N1 influenza vaccine
  • Subject is at high risk of contracting H5N1 influenza infection (e.g. poultry workers)
  • Subject currently has or has a history of a significant cardiovascular (including hypertension), respiratory (including asthma), metabolic, neurological (including Guillain-Barré Syndrome and acute disseminated encephalomyelitis), hepatic, rheumatic, autoimmune, hematological, gastrointestinal or renal disorder
  • Subject has any inherited or acquired immunodeficiency
  • Subject has a disease or is currently undergoing a form of treatment or was undergoing a form of treatment within 30 days prior to study entry that can be expected to influence immune response. Such treatment includes, but is not limited to: systemic or inhaled corticosteroids, radiation treatment, or other immunosuppressive or cytotoxic drugs
  • Subject has a history of severe allergic reactions or anaphylaxis
  • Subject has a rash, dermatologic condition or tattoos which may interfere with injection site reaction rating
  • Subject has received a blood transfusion or immunoglobulins within 90 days prior to study entry
  • Subject has donated blood or plasma within 30 days prior to study entry
  • Subject has received any influenza or any live vaccine within 4 weeks or any other inactivated vaccine within 2 weeks prior to vaccination in this study
  • Subject has a functional or surgical asplenia
  • Subject has a known or suspected problem with alcohol or drug abuse
  • Subject was administered an investigational drug within 6 weeks prior to study entry or is concurrently participating in a clinical study that includes the administration of an investigational product
  • Subject is a member of the team conducting this study or is in a dependent relationship with one of the study team members. Dependent relationships include close relatives (i.e., children, partner/spouse, siblings, parents) as well as employees of the investigator/subinvestigator or site personnel conducting the study
  • If female, subject is pregnant or lactating at the time of enrollment
  • Subject has any other condition that disqualifies his/her participation in the study in the opinion of the investigator
