In this video interview, we discuss vaccine hesitancy, first in measles as a historical backdrop, then for a potential or soon-to-be FDA authorized COVID-19 vaccine. Dr. Abram Wagner, research assistant professor of epidemiology at the University of Michigan, joins us to discuss recent research on vaccine hesitancy. His research looks at evidence-based programs and policies to control vaccine-preventable diseases. He currently holds a grant from the National Science Foundation that looks at behaviors and acceptance of a COVID-19 vaccine over time and across several regions, including the United States, India, and Taiwan.
