SEROLOGIC CORRELATES OF PROTECTION AGAINST BACILLUS ANTHRACIS INFECTION

摘要

Regions of B. anthracis protective antigen are provided representing sequences recognized by antibodies in subjects that have vaccine induced lethal toxin neutralizing anti-PA IgG responses. The recognition of these PA regions enhances the utility of anti-PA IgG reactivity as an immune correlate of protection against anthrax in a subject and increases predictive probability of survival. Also provided are vaccines that include at least one of these PA regions that when administered to a subject improve the predictive value of vaccine induced anti-PA IgG and TNA responses as immune correlates of protection against inhalation anthrax.
