Popis: Introduction Understanding changes in vaccine hesitancy, overall and by sociodemographic characteristics, may highlight sub-populations for whom more intensive efforts are needed to increase vaccine uptake and confidence.Methods We analyzed data using the CDC’s Research and Development Survey (RANDS), a nationally representative survey of U.S. adults ≥18 years, collected from 17 May 2021–30 June 2021 (n = 5,458) and 3 November 2022–12 December 2022 (n = 6,821). We assessed changes in vaccine hesitancy, changes in vaccine attitudes and attitudes, and factors associated with hesitancy toward both vaccines in general and COVID-19 vaccines among a nationally representative sample of U.S. adults.Results Although COVID-19 vaccination (≥1 dose) increased from 67.2% (2021) to 74.7% (2022), COVID-19 vaccine hesitancy increased from 40.7% to 44.6% during the same period. During the same period, hesitancy toward both COVID-19 vaccines and vaccines in general increased among those who were aged ≥65 years and who were non-Hispanic White. However, COVID-19 vaccine hesitancy decreased among non-Hispanic Black adults. Current or former smokers were more hesitant toward vaccines in general (aPR = 1.13, 95%CI: 1.03–1.24) and toward COVID-19 vaccines (aPR = 1.08, 95%CI: 1.01–1.16) compared to never smokers. Among adults who did not receive any COVID-19 vaccines, COVID-19 vaccine hesitancy increased from 86.6% in 2021 to 92.4% in 2022. Furthermore, belief in the overall social benefit of the COVID-19 vaccine decreased from 47.5% to 25.1%.Conclusion This study highlights concerning trends in vaccine hesitancy and uptake of the COVID-19 and other recommended vaccines. We found that some high-risk groups (e.g. smokers) and population subgroups have become more vaccine hesitant, suggesting the need for improved and intensified strategies to increase vaccine confidence and uptake. Future research may focus on qualitative inquiry to understand specific concerns and determinants contributing to increased hesitancy among these groups to help inform interventions and communication campaigns to support vaccination.
