title: [How and when is immunotherapy for pollen allergy carried out?].
abstract: Hyposensitization with semi-depot extracts was effective in 164 of 201 (81,4%) grass pollen sensitive patients. In 54,1% the results were very good and good. Patients were treated perennially for two years. The success of treatment was evaluated by a questionnaire. The results show that treatment will be most effective if the disease has been of relative short duration, if patients are young, if the final dosage is high and a high total dosage is reached, and if side effects only occur as local reactions. The frequency of symptoms and their improvement are described.
