A Self-Assembling Whole-Cell Vaccine Antigen Presentation Platform.

ABSTRACT: Diarrhea is the most common infection in children under the age of 5 years worldwide. In spite of this, only a few vaccines to treat infectious diarrhea exist, and many of the available vaccines are sparingly and sporadically administered. Major obstacles to the development and widespread implementation of vaccination include the ease and cost of production, distribution, and delivery. Here we present a novel, customizable, and self-assembling vaccine platform that exploits the Vibrio cholerae bacterial biofilm matrix for antigen presentation. We use this technology to create a proof-of-concept, live-attenuated whole-cell vaccine that is boosted by spontaneous association of a secreted protein antigen with the cell surface. Sublingual administration of this live-attenuated vaccine to mice
