Detailed Description:

This is a clinical study in which there is no vaccine administered. It is designed for research purposes such as developing immunological assays.


Ages Eligible for Study:   18 Years to 45 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Subjects who the investigator believes can and will comply with the requirements of the protocol.
  • Written informed consent obtained from the subject.
  • Healthy subjects (except the condition studied in the ALLERGY group).
  • A male or female between, and including 18 and 45 years of age at the time of study start.
  • Subject presenting moderate to severe clinical symptoms of allergy within the week before enrolment (only for ALLERGY group).
  • Subjects suffering from seasonal allergy to birch pollen previously documented by a medical history (only for ALLERGY group).
  • A positive skin prick test response realised and/or a positive test for specific IgE against birch within the last 5 years (only for ALLERGY group).

Exclusion Criteria:

  • Any known or clinical signs of anaemia or any condition that would preclude the drawing of blood as described in the protocol.
  • Receipt of blood products 120 days prior to study visit.
  • Receipt of immunoglobulin 120 days prior to study visit.
  • Use of any investigational or non-registered product within 30 days preceding the study visit.
  • Concurrently participating in another clinical study, at the time of the study visit, in which the subject has been or will be exposed to an investigational or a non-investigational product.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history.
  • Any confirmed or suspected autoimmune or inflammatory disorders.
  • Administration of systemic or inhaled anti-inflammatory medications and, in particular, inhaled corticoid-steroids and cromoglycates within 30 days preceding the study visit. Purely local medications such as intranasal steroids or systemic symptomatic medications such as antihistamines and beta agonists are allowed.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the study visit.
  • Pregnant or lactating female.
  • Any past or current birch-specific immunotherapy (only for ALLERGY group).
  • Any allergic disease as established by medical history before study start (only for CONTROL group).
  • Family history of allergic diseases in the first degree family members (only for CONTROL group).
