First vaccine developed against grass pollen allergy

Around 400 million people worldwide suffer in some form or other from a grass pollen allergy (rhinitis), with the usual symptoms of runny nose, cough and severe breathing problems. In collaboration with the Viennese firm Biomay AG, MedUni Vienna researchers at the Institute of Pathophysiology and Allergy Research have now shown in a Phase II-b study with 180 patients in 11 European centres, that four injections of the synthetically manufactured vaccine BM32 in the first year and a top-up in the second year of treatment relieve the sufferers' symptoms by at least 25 percent.
