Abstract
Standardized allergen vaccines have been developed and registered as biopharmaceutical products in Cuba. Three different vaccines were obtained from the most relevant allergenic mite species: Dermatophagoides pteronyssinus, Dermatophagoides siboney, and Blomia tropicalis. Immuno-analytical methods based on murine monoclonal antibodies and human IgE antibodies were developed for assessing allergenic potency, composition, and stability. Preclinical and clinical studies showed efficacy and safety in diagnostic prick-tests and subcutaneous immunotherapy in asthmatic patients. New approaches are now undertaken in order to develop new adjuvanted formulations based on liposomes or proteoliposomes from Neisseria meningitidis, and purified allergens; aiming to overcome the drawbacks of conventional immunotherapy.
