"Emergent BioSolutions (NYSE: EBS) -- my top 2009 pick -- makes the only FDA-licensed vaccine for the prevention of anthrax," says Timothy Lutts in his The Cabot Stock of the Month.

"Located in Rockville, Maryland, the company is currently filling a $448 million government order for 18.75 million doses, and in October, the U.S. government contracted to purchase 14.5 million additional doses valued at up to $404 million, to add to the Strategic National Stockpile.

"The vaccine is named BioThrax, and it accounts for 97% of the revenues of Emergent BioSolutions. However, the company has a full pipeline including two 'next generation' anthrax vaccines.

"Also in development are two anthrax therapeutics (immunoglobulin and monoclonal), two botulinum vaccines and a botulinum therapeutic (botulinum is the nasty form of Botox), an oral typhoid vaccine, a next generation tuberculosis vaccine, a hepatitis B immunotherapy and a chlamydia vaccine.
