St. Mary’s Hospital and UW Health, both in Madison, will operate as regional distribution hubs for the Pfizer vaccine. “These vaccines will be going to frontline healthcare workers first, and there are still uncertainties around the quantities we’ll get and the timing of their arrival,” Matt Anderson, senior medical director of ambulatory operations with UW Health, said in a statement. “The public must remain diligent as it will not be widely available anytime soon.”
