Changes in COVID-19 vaccination receipt and intention to vaccinate by socioeconomic characteristics and geographic area, United States, January 6 - March 29, 2021.

Intent 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 MESSAGESReceipt 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.[Formula: see text].
