B cells are a type of white blood cell that produces specific antibodies when exposed to a virus or bacteria. These antibodies can then bind to the pathogen and help to neutralize or eliminate it from the body. In this case, if Mary's immune system has encountered the specific virus before, the B cells will recognize it and produce antibodies to help protect against the infection.
