The researchers said people who do not get inoculated for diseases that can be prevented by vaccines cost the U.S. economy more than $7 billion a year.
The bill for diseases that vaccines can prevent is $8.95 billion annually. Unvaccinated individuals account for 80 percent of that figure, or $7.1 billion, the researcher said.
The most expensive preventable disease is the flu virus, which in 2015 accounted for nearly $5.8 billion in healthcare costs and lost productivity.
