Pfizer Inc. workers are bracing for hundreds of layoffs at the drug giant’s factory in Rocky Mount, North Carolina.

About 2,000 people work at the plant, which was acquired from Hospira Inc. as part of a $17 billion deal last year. Pfizer has been selling off Hospira assets since the acquisition closed.

A Pfizer spokesperson declined to confirm that 400 people will be cut, in response to reporter questions, according to WRAL TechWire.

"Based on current information, we expect the production level changes will impact a few hundred full time roles in the second half of 2016," a Pfizer spokesperson said in a statement.

Pfizer in August cut 151 workers from a factory in Pearl River, New York, according to The Journal News.

“The layoffs are part of the company's 2010 announcement that it would phase out vaccine manufacturing in Pearl River,” the newspaper reported, citing a spokesperson. “At that time there were more than 4,000 people employed at the North Middletown Road campus.”
