Three workers in a downtown Seattle research laboratory were infected with tuberculosis while working on a vaccine for the deadly disease, state officials say.
L&I and IDRI reported the incident to the University of Wisconsin, which makes the Madison chamber, as it is called. But officials there said they didn’t think it necessary to alert any of the other 15 to 25 institutions using the chamber. The chamber operates with a vacuum, so no germs should get out, said Todd Kile, shops manager for the University of Wisconsin’s College of Engineering.
