Emergent BioSolutions Inc. (EBS) announced today that the Drugs Controller General of India (DCGI) has issued a registration certificate for BioThrax® (Anthrax Vaccine Adsorbed), which enables the marketing and sale of the vaccine in India to help prevent anthrax infection. Emergent BioSolutions has signed a marketing agreement with Biological E. Limited for the marketing of BioThrax in India. BioThrax is the only vaccine for the prevention of anthrax infection licensed by the U.S. Food and Drug Administration (FDA).

The BioThrax market authorization for India follows the publication in 2008 of the National Disaster Management Guidelines by the Indian National Disaster Management Authority (NDMA), which is the government body that oversees disaster management. In that document, the government of India provided guidance with respect to the management of biological disasters and stated that there is a need to have a supply of readily available anthrax vaccines to be administered rapidly in the event of an outbreak. The report goes on to state that all first responders will be vaccinated in an impending disaster situation.

Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions, stated, “The Government of India has been explicit in expressing its commitment to protect its population from the continuing threat of bioterrorism. We are certainly pleased that BioThrax will be a valuable countermeasure available to the Government of India to achieve that goal. Today marks a pivotal milestone in Emergent’s efforts to expand globally and further our mission of protecting life.”
