| Abstract: | IntroductionPrevious studies suggested that almost one-third of U.S. adults did not plan to get a COVID-19 vaccine once it is available to them. The purpose of this study was to examine changes in vaccine intentions and attitudes by sociodemographic characteristics and geographic areas, factors associated with vaccination intent, and reasons for non-vaccination among a nationally representative sample of U.S. adults.MethodsData from six waves of the Household Pulse Survey (6 January – 29 March 2021) were analyzed. Differences between January and March were assessed using t-tests. Factors associated with vaccination intent were examined in multivariable logistic regression models.ResultsFrom early January to late March, vaccination receipt of ≥1 dose of the COVID-19 vaccine or intention to definitely get vaccinated increased from 54.7 to 72.3%; however, disparities in vaccination intent continued to exist by age group, race/ethnic groups, and socioeconomic characteristics. Vaccine receipt and the intent were the lowest for region 4 (southeastern U.S.) throughout this period. Adults who had a previous COVID-19 diagnosis or were unsure if they have had COVID-19 were less likely to intend to get vaccinated prevalence ratio = 0.92 (95%CI: 0.90–0.93) and 0.80 (95%CI: 0.74–0.85), respectively]. The belief that a vaccine is not needed increased by more than five percentage points from early January to late March.ConclusionIntent to definitely get a COVID-19 vaccine increased by almost 18 percentage points from early January to late March; however, younger adults, adults who are non-Hispanic Black or other races, adults of lower socioeconomic status, and adults living in the southeastern U.S. region (Region 4) continue to have higher coverage gaps and levels of vaccine hesitancy. Emphasizing the importance of vaccination among all populations, and removing barriers to vaccines, may lead to a reduction of COVID-19 incidence and bring an end to the pandemic.KEY MESSAGES- Receipt of ≥1 dose of the COVID-19 vaccine and intent to probably or definitely get vaccinated increased from early January to late March; however, disparities in vaccine intent continued to exist by age group, race/ethnic groups, and socioeconomic characteristics.
- Vaccine receipt and the intent were the lowest for region 4 (southeastern U.S.) compared to other regions during this period.
- Adults who had a previous COVID-19 diagnosis or were unsure if they have had COVID-19 were less likely to intend to get vaccinated; overall, the belief that a vaccine is not needed to be increased by more than 5% points from early January to late March.
