Unvaccinated people are 'variant factories,' infectious diseases expert says - CNN: Unvaccinated people do more than merely risk their own health. They're also a risk to everyone if they become infected with coronavirus, infectious disease specialists say. That's because the only source of new coronavirus variants is the body of an infected person. "Unvaccinated people are potential variant factories," Dr. William Schaffner, a professor in the Division of Infectious Diseases at Vanderbilt University Medical Center, told CNN Friday.
