• Able and willing to provide written informed consent
• Able and willing to complete all protocol requirements
• 18 to 65 years of age
• History of persistent asthma according to GINA 2007 guidelines whose symptoms requiring long-term treatment with ICS
• Positive skin prick test to at least one aero-allergen and anamnestically confirmed to cause asthma symptoms. In case of doubt the allergic nature of the asthma must be confirmed by nasal provocation with the suspected allergen.
• FEV1 >60% of predicted value
• FEV1 improvement >=12% after inhaled beta2-agonist (400 µg salbutamol) at screening
• Airway responsiveness to methacholine (PC20 <8 mg/mL) at screening (prior to run-in phase)
• On stable therapy with ICS equivalent to a dose of =500 µg BDP daily (short-acting beta2-agonists (salbutamol) as needed may be used throughout the whole study)
• Clinically stable asthma or sufficiently controlled asthma at screening and prior to treatment phase as indicated by <1.5 mean points in the Asthma Control Questionnaire (ACQ)
• Female participants must meet one of the following criteria:
- No reproductive potential due to menopause (one year without menses, in case of doubts serum FSH will be determined and must be >30 U/mL and estradiol must be <54.7pg/mL), hysterectomy, bilateral oophorectomy, or tubal ligation
- Patient agrees to consistently practice an effective and accepted method of contraception throughout the duration of the study and for 1 additional month after the last immunization (hormone-based, or intrauterine device, or double barrier contraception, i.e. condom + diaphragm, condom or diaphragm + spermicidal gel or foam)

• Use of oral corticosteroids within past 3 months
• Hospitalization for asthma exacerbation within past 6 months
• Uncontrolled asthma defined by ACQ =1.5 points at screening or prior to treatment phase
• Intermittent or seasonal asthma not requiring ICS treatment
• Regular use of long-acting beta2-agonists (LABA). All LABAs should be discontinued after informed consent and at least 48h prior to the screening procedure to ensure appropriate washout.
• Smokers or quitters with a smoking history of >10 packyears (one package per day for 10 years)
•Major surgery within 4 weeks prior to enrollment

For psoriasis, family history should also be clean.
• Current diagnosis or history of malignancy; presence of suspicious lymphadenopathy or splenomegaly on physical examination
• Confirmed or suspected current infection with HIV, HBV, or HCV
• Presence of active infectious disease as judged by the investigator
• History of recurrent invasive streptococcal or staphylococcal infections, or known interleukin-1 receptor-associated kinase 4 (IRAK 4) deficiency
• Active autoimmune diseases
• Pregnancy (based on positive urine test at screening visit) or lactation
• Female planning to become pregnant during the study period
• Blood donation or loss of > 400 mL within 8 weeks prior to inclusion
• Vaccination planned during study treatment period
• History of abuse of alcohol or other recreational drugs
• Lactose intolerance
• Any specific immunotherapy (SIT) planned during the whole study period or any former SIT within the last three years.
• Treatment with anti-IgE antibodies within past 6 months
• Use of any investigational drug within 30 days before enrolment, or planned use during the whole study period
• Previous participation in a clinical trial with a Qb-based vaccine
• Possible dependency of the patient on sponsor and/or investigator
