Dozens of Researchers Exposed to Anthrax

As many as 75 scientists at the US Centers for Disease Control and Prevention may have come in contact with live Bacillus anthracis, the bacteria that cause anthrax.

CDC scientists were studying the bacteria in a high-level biosecurity lab and then transferred the samples to three lower-security labs without first properly inactivating the live microbes. Workers in those labs handled the samples without using personal protective equipment, such as gloves. The procedural lapse happened between June 6 and June 13, and CDC spokesperson Thomas Skinner told The New York Times that while none of the researchers exposed to the bacteria are showing symptoms of infection, many of them are receiving prophylactic antibiotic treatment “out of an abundance of caution.”

CNN reported on Thursday afternoon that 54 CDC employees determined to have been in the labs or hallways at the time live anthrax was present have been seen by the agency’s Occupational Health Clinic. Of those, only two people chose not to take oral antibiotics. An additional 27 staffers have been given the anthrax vaccine. Other exposed individuals were scheduled to be seen by doctors on Friday.

Paul Meechan, director of the environmental health and safety compliance office at the CDC, told The Guardian that the agency discovered the exposure on the evening of June 13 and is conducting an internal investigation to determine how the lapse occurred. “This should not have happened,” he said. “We’re taking care of it. We will not let our people be at risk.”

“We will report findings of this review and all steps we take to improve lab-safety processes as a result of this incident,” the CDC’s statement read.

I find it somewhat concerning that as a soldier in the US Army, I was required to get a series of anthrax vaccinations in the event I might get exposed to anthrax. But, scientists and technicians that work with, or in areas where anthrax is used, are not vaccinated prior to exposure.

Shouldn't this be a condition of employment?

Soldiers need to remain in top fighting form at all times to fight in the war such a weaponized bio agent would be used in. (Also the vaccine cost is covered by the defense budget which is far greater than the CDC's annual allotment.)

From an economical stand point it's cheaper to treat the scientists if they happen to be exposed, than to vaccinate against potential exposure.
