Simplified monomeric monoclonal antibodies consisting of a single-domain VHH, derived from camelid heavy-chain only antibodies, fused with the Fc domain of either IgG (VHH-IgG) or IgA (VHH-IgA) antibodies, are promising therapeutic proteins. These simplified single-gene encoded antibodies are much easier to manufacture and can be produced in plants and in yeast for bulk applications. These merits enable novel passive immunization applications, such as in-feed oral delivery of VHH-IgAs, which have successfully provided protection against a gastrointestinal infection in the piglet model.
