Plasmid vectors encoding a protein of a picornavirus

Abstract

The invention relates to an active principle of a vaccine, in which the characteristic epitope is incorporated in the capsid of a picornavirus, in particular of poliovirus, used as a vector. This active principle consists of a viable hybrid picornavirus containing an epitope characteristic of a vaccinating protein, and heterologous with respect to the proteins of this picornavirus, in place of one of its own immunogenic epitopes.
