Introduction Previous 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. Methods Data 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. Results From 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. Conclusion 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 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.

Introduction There was a five-fold increase in COVID-19 hospitalization case counts among children and adolescents between June and October 2021. However, polls suggest that adolescent COVID-19 vaccination coverage has plateaued in the United States. Methods Using the Census Bureau’s Household Pulse Survey, we assessed trends in COVID-19 vaccination among adolescents ages 12–17 years, parents’ intention to vaccinate their adolescent children, and their reasons for not intending to vaccinate their children from July to October 2021 using a large, nationally representative survey of U.S. households ( n = 59,424). Trends in COVID-19 adolescent vaccination coverage, nationally and by sociodemographic characteristics, factors associated with adolescent vaccination status and parental intent to vaccinate their adolescent children, as well as changes in reasons for non-vaccination were examined using regression models. Results Receipt of ≥1 dose of a COVID-19 vaccine among adolescents ages 12–17 years increased five percentage points, from 56% (July) to 61% (October), with significant increases across most sociodemographic variables. However, there were no significant changes in parental intention to vaccinate their adolescent children during the same time period. Approximately one-quarter of parents were unsure about or reluctant to vaccinate their children, which remained consistent from July to October. Among those who had not vaccinated their children, lack of trust in the government and vaccines, and the belief that the COVID-19 vaccine is not needed or effective, was higher in October compared to July. Conclusions Parental intention to vaccinate their children has remained relatively stable throughout the late summer and early fall of 2021. Encouraging paediatricians to discuss the importance and safety of COVID-19 vaccines, addressing concerns and misinformation, as well as recommending and offering vaccines are important for increasing parental confidence in vaccines as well as vaccination uptake among adolescents.

Background and Objectives: Stay-at-home orders, social isolation recommendations, and fear of COVID-19 exposure have led to delays in children’s preventive health services during the pandemic. Delays can lead to missed opportunities for early screening and detection of health problems, and increased risks for outbreaks of vaccine-preventable diseases. Understanding prevalence of and reasons for missed, delayed, or skipped preventive health services is important for developing strategies to achieve rapid catch-up of essential health services. Methods: Using the Household Pulse Survey (n=37,064), a large, nationally-representative household survey fielded from April 14 to May 10, 2021, we examined prevalence of households with children who have missed, delayed, or skipped preventive health services, and factors associated with and reasons contributing to missed, delayed, or skipped preventive health services. Results: About one-quarter of parents had children who missed, delayed, or skipped preventive check-ups in the past year. Delays in children’s preventive health services were more common among respondents with higher education, households with greater numbers of children, and children who learned remotely or did not participate in formal education. Main reasons attributed to delayed preventive health services were limited appointments at health providers’ offices (42.9%), concern about COVID-19 exposure at health providers’ offices (42.2%), and closed health providers’ offices due to the pandemic (29.0%). Conclusions: Physician office closures and concern about COVID-19 exposure resulted in over one-quarter of parents delaying preventive services for their children since the pandemic began. Coordinated efforts are needed to achieve rapid catch-up of preventive services and routine vaccines.

To assess trends in and factors associated with COVID-19 vaccination (≥ 1 dose) coverage, data from the Household Pulse Survey were analyzed. From April–August 2021, vaccination coverage with at least one dose increased from 70% to 82%, while vaccination intent increased from 82% to 86%, with the highest increase among the most vulnerable groups. More efforts are needed to boost confidence in vaccines and to encourage all eligible people to be fully vaccinated.
