Brief Summary
The purpose of this study is to evaluate the residual allergenicity of Tree MATA (modified pollen allergen tyrosine adsorbate) by skin prick testing. This is done by a comparison of the wheal response after skin prick testing with aqueous native and modified allergen, modified tyrosine adsorbed allergen and Tree MATA MPL (modified tyrosine adsorbed + MPL \[Monophosphoryl Lipid A\]).

Eligibility Criteria
You may qualify if:
- The subject must sign the study consent form prior to any screening procedures being performed.
- If the volunteer is female of childbearing potential, she must demonstrate a negative urine pregnancy test and agree to remain abstinent or use an effective method of birth control or use a hormonal contraceptive
- The subject must demonstrate a positive skin prick test to Birch, Hazel and Alder pollen allergen extract
- The subject must demonstrate a positive skin prick test to positive histamine control
- The subject must demonstrate a negative skin prick test to negative control
- The subject must demonstrate a specific IgE for Birch, Hazel and Alder as documented by a RAST (radioallergosorbent test), or equivalent test
- The subject must have clinically acceptable results from the screening procedure.
You may not qualify if:
- History or presence of acute or subacute atopic dermatitis, chronic dermatitis, urticaria factitia, or urticaria due to physical/chemical influence or any other skin conditions which might interfere with the interpretation of skin prick test results
- Visual inspection of the forearms indicates potential problems with the conduct or interpretation of the skin prick tests; both forearms must be available for testing
- Subject has asthma or other lower respiratory tract condition
- History or presence of diabetes, cancer or any clinically significant cardiac, metabolic, renal, hepatic, gastrointestinal, dermatologic, venereal, hematologic, neurologic or psychiatric diseases or disorders
- Any clinically significant abnormal laboratory value at Visit 1
- Clinically relevant sensitivity to any common perennial allergen: house dust mites, molds, epithelia (cat, dog, and horse), grass mix
- Secondary alteration at the affected organ.
- History of auto-immune diseases or rheumatoid diseases
- Subject has a medical condition that prohibits the use of adrenalin
- Subject has disorder of tyrosine metabolism
- Subject with diseases interfering with the immune response and have received medication, which could influence the results of this study
- Subject has acute or chronic infection
- History of anaphylaxis
- History of angioedema
- Subjects determined by the Investigator to have any medical condition that could jeopardize their health or prejudice the results
