Most traditional vaccines have safety and efficacy issues, whereas particulate vaccine delivery systems—which utilize nano- or micro-particulate carriers to protect and deliver antigens—are efficient, stable, include molecules to bolster immune responses, and minimize adverse reactions due to the use of biocompatible biomaterials.

A new review, titled “Particulate delivery systems for vaccination against bioterrorism agents and emerging infectious pathogens,” summarizes the current status of research efforts to develop particulate vaccine delivery systems against bioterrorism agents and emerging infectious pathogens.
