Schematic representation of viral delivery vehicles that have been tested for use in allergy immunotherapy. (A) Viral and phage delivery vehicles displaying allergen-derived peptides (red) on their surface. (B) Virus-like particles as delivery vehicles of allergens or allergen-derived peptides (red) that are incorporated into the virus-like particle either by chemical coupling or by recombinant expression as fusion proteins. (C) Single viral (yellow) and phage surface protein carriers (green and blue) of allergen-derived peptides.
