NCT03375775

Brief Summary

The objective is to prospectively explore associations between immunological parameters in blood and clinical effect of subcutaneous immunotherapy (SCIT) in children with severe allergy towards pollen. Half of the children will receive SCIT while the other half will start SCIT after the study is finished. Clinical evaluations of symptoms and an immunological survey will be performed before start of SCIT and after one year of treatment. Some of the immunological parameters will also be checked after 6 months of treatment
