BioThrax Anthrax Vaccine Description

BioThrax, Anthrax Vaccine Adsorbed, is made from cell-free filtrates of microaerophilic cultures of an avirulent, nonencapsulated strain of Bacillus anthracis.

BioThrax is intended to stimulate the production of neutralizing antibodies that recognize the vaccine antigens, protective antigen (PA), lethal factor, and edema factor and are expected to be protective against Bacillus anthracis infection.

The efficacy of BioThrax has not been evaluated through clinical trials. Vaccine efficacy has been inferred from immunogenicity data, including anti-PA IgG and toxin neutralization titers.

Gaithersburg, Maryland-based Emergent BioSolutions is a global life sciences company whose mission is to protect and enhance life.
