Early in the COVID-19 pandemic, Black Americans were more hesitant to take the COVID-19 vaccine than were white Americans. As the pandemic went on, however, the disparity in vaccination rates between Black and white adults declined. In a paper titled "What Caused the Narrowing of Black-White COVID-19 Vaccination Disparity in the US? A Test of 5 Hypotheses," published in the current issue of the Journal of Health Communication, researchers at the Annenberg Public Policy Center (APPC) of the University of Pennsylvania assessed explanations for the positive change.
Using April 2021 to July 2022 data from the Annenberg Science and Public Health (ASAPH) survey, a national panel of over 1,800 U.S. adults, the team, led by APPC research director Dan Romer, assessed potential explanations, including increased trust in the Centers for Disease Control and Prevention (CDC), exposure to pro-vaccination messages in the media, awareness of COVID-inflicted deaths among personal contacts, and improved access to vaccines.
None of these factors explained the decline in disparity, however. Only increased knowledge about COVID-19 vaccination made a difference. Knowledge about the COVID vaccine among Black Americans increased over time, and this increase was associated with their receipt of the vaccine.
"Black Americans became less skeptical of the safety and efficacy of the vaccine as time proceeded, which appeared in our data to be an important contributor to increased vaccination rates among t.
