Summary:: A team of researchers has now engineered a virus nanoparticle vaccine against Bacillus anthracis and Yersinia pestis, tier 1 agents that pose serious threats to national security of the United States. B. anthracis and Y. pestis are the pathogens that cause anthrax and plague, respectively. Using bacteriophage T4, the scientists developed the vaccine by incorporating key antigens of both B. anthracis and Y. pestis into one formulation. Two doses of this vaccine provided complete protection against both inhalational anthrax and pneumonic plague in animal models.

A team of researchers has now engineered a virus nanoparticle vaccine against炭疽杆菌andYersinia pestis, tier 1 agents that pose serious threats to national security of the United States.B. anthracisandY. pestisare the pathogens that cause anthrax and plague, respectively. Using bacteriophage T4, the scientists developed the vaccine by incorporating key antigens of bothB. anthracisandY. pestisinto one formulation. Two doses of this vaccine provided complete protection against both inhalational anthrax and pneumonic plague in animal models. Even when animals were threatened with lethal doses of both anthrax lethal toxin andY. pestisCO92 bacteria, the vaccine was shown to be effective.

The study is published inmBio, an open-access journal of the American Society for Microbiology.

"This dual anthrax-plague vaccine is a strong candidate for stockpiling against a potential bioterror attack involving either one or both of these biothreat agents," the researchers noted in the study. Their results demonstrate that T4 nanoparticle is a novel platform for developing multivalent vaccines against pathogens of high public health concern.
