PAVax is an innovative, international, intersectorial and interdisciplinary doctoral training network that aims at the education of a new generation of glycoscientists able to provide key findings for the design of new carbohydrate-based vaccines for the prevention of Pseudomonas aeruginosa (PA) and Staphylococcus aureus (SA) infections. Antibiotic resistance of these bacteria seriously thwarts therapeutic intervention of these infections.
