Even though nearly three-fourths of adults in the U.S. had received at least one dose of a COVID-19 vaccine as of early September, vaccine hesitancy remains an important public health concern worldwide, hampering efforts to contain the pandemic.
Although not a new phenomenon, the topic has taken on a greater urgency because of the pandemic. Researchers are trying to understand what it takes to change the minds of individuals who are still not convinced they should get the COVID-19 vaccine for themselves or their eligible children.
This has prompted a surge in studies that aim to better understand why people are vaccine hesitant and what it takes to increase their confidence in the COVID-19 vaccines. At the end of 2020 there were 92 studies on COVID-19 vaccine hesitancy posted on the National Library of Medicine’s PubMed research database. As of Sept. 3, that number had climbed to 751.
To help journalists with their reporting, we’ve gathered several data sources and research studies that shed light on wider trends in vaccine hesitancy and explore the reasons why certain groups remain wary of COVID-19 shots.
