# HAL Allergy Group

HAL Allergy Group is a pharmaceutical company that develops, produces and sells products for allergy diagnostic and allergen immunotherapy (AIT). The research facilities and headquarters are located at the Leiden Bio Science Park, Netherlands.
The focus since 1959 stems from the development, production and distribution of allergen immunotherapies for the treatment and prevention of allergic diseases. These immunotherapies produced are subcutaneous (SCIT) or sublingual (SLIT) administrated and used primarily against common allergies such as hay fever, house dust mite allergy and allergic reactions towards wasp or bee stings. With offices in major European countries, HAL Allergy is one of the European top players, particularly in the field of allergy.
In addition, HAL Allergy has a specific expertise in the area of contract manufacturing with focus on the production of biopharmaceutical products for preclinical and clinical studies. This is done by its subsidiary HALIX B.V.
HAL Allergy originally stems from 'Haarlems Allergenen Laboratorium', a Dutch company set up in Haarlem. The company started as a small laboratory where, on request of several local general practitioners (GPs), extracts were prepared on a named patient basis to treat against allergic reactions.

## History

HAL Allergy was established in 1959. At the time of its inception it was located in the centre of Haarlem. The name HAL Allergy comes from 'Haarlems Allergenen Laboratorium'.
The founder of HAL Allergy Johan Kuijper identified at an early stage the relevance of standardisation and stability of allergen extracts as well as being one of the initiators of the establishment of a European Clearing House for allergen extracts from which the Paul Ehrlich Seminars originated.
In the 1970s, the company began exporting to Germany on larger scale. Over the years, the product portfolio has seen changes and development. In January 2007 the company moved from Haarlem to bigger premises at the Bio Science Park in Leiden in the Netherlands
Aside from the development and production of allergy vaccines, HAL Allergy started a contract manufacturing organization (CMO) in 2012, named HALIX that is engaged in the production of biotechnological products for preclinical and clinical studies.
