About respiratory allergies in Argentina
The prevalence of allergic rhinitis in Argentina is estimated at between 20% and 30% of the population.
The Argentinean market offers substantial potential for the development of allergen immunotherapy: 8.5 million people are sensitized and the most prevalent allergen is house dust mites. Each year, 2.3 million people are diagnosed with allergy symptoms.

Today, only 150,000 allergy sufferers are treated with allergen immunotherapy. There is therefore a strong need for innovative standardized allergen immunotherapy treatments.

For more than 50 years, it has been continuously expanding the existing frontiers of science in order to provide allergy patients with more effective long lasting therapeutic options. Thanks toits innovation strategy, fueled by investments amounting to around 20% of total annual revenues as well as external partnerships, STALLERGENES is able to provide targeted allergen immunotherapy-based allergy solutions that significantly improve the lives of allergy patients around the world.

STALLERGENES operates in 20 countries and employs over 1,000 people. In 2013, the Company generated total revenues of €248 million, and more than 500,000 patients were treated with STALLERGENES products.
