Summer eczema, also called sweet itch or insect bite hypersensitivity (IBH) is the most prevalent allergic skin disease in horses. It manifests as chronic relapsing seasonal allergic dermatitis (inflammatory reaction of the skin).

Although IBH is the best studied and characterized allergic disease of horses, treatment options are still poor and not even close to satisfactory. Our vision is to end this suffering, developing a vaccine that therapeutically treats and prophylactically prevents summer eczema.
