Hope for a vaccination against Staphylococcus areus infections?
Staphylococcus aureus (S. aureus) ranks among the globally most important causes of infections in humans and is considered a dreaded hospital pathogen. Active and passive immunisation against multi-resistant strains is seen as a potentially valuable alternative to antibiotic therapy. However, all vaccine candidates so far have been clinically unsuccessful. With an epitope-based immunisation, scientists at Cologne University Hospital and the German Center for Infection Research (DZIF) have now described a new vaccination strategy against S. aureus in the Nature Partner Journal NPJ VACCINES.
