I am fascinated by the minimalist vaccine strategy referred to as epitope-based or peptide-based, which of course can be delivered as a DNA construct for greater stability (peptides can degrade easily and have a short half-life), and the idea of using conserved epitopes as a way to address the issue of viral/pathogen…
