More than 10% of the U.S. population has received at least one dose of the COVID-19 vaccine, but injection rates are lower in black and brown communities, and many people express doubts about the shots made by Pfizer-BioNTech and Moderna. Vaccine hesitancy presents a barrier in the fight against coronavirus.

A recent poll by Pew Research Center found that "Black Americans continue to stand out as less inclined to get vaccinated than other racial and ethnic groups: 42% would do so, compared with 63% of Hispanic and 61% of White adults."

Our guest, Dr. Wrenetha Julion, professor and department chair at Rush University College of Nursing, discusses causes of vaccine hesitancy and how to encourage more people to take a high-effective vaccine against the virus.
