This article describes perceptions of the COVID-19 vaccine among US adults, and reports that younger adults, women, non-Hispanic Black adults, adults living in nonmetropolitan areas, adults with less education and income, and adults without health insurance have the highest estimates of nonintent to receive vaccination; due to concerns about side effects and safety of the COVID-19 vaccine, lack of trust in the government, and concern that COVID-19 vaccines were developed too quickly are the primary reasons for deferring vaccination. Solid organ transplant candidates and recipients may harbor similar concerns about vaccination, and further, may rely more heavily on herd immunity for protection from COVID-19, since the efficacy of COVID-19 vaccination among immunosuppressed individuals remains ill-defined. Promoting vaccine confidence among transplant candidates, transplant recipients, and the general population will thus be critical to preventing spread of COVID-19.

As of February 8, 2021, 59.3 million doses of vaccines to prevent coronavirus disease 2019 (COVID-19) had been distributed in the United States, and 31.6 million persons had received at least one dose of the COVID-19 vaccine.1CDCCOVID data tracker: COVID-19 vaccinations in the United States. US Department of Health and Human Services. CDC, Atlanta, GA2021Google Scholar However, national polls conducted before vaccine distribution began suggested that many persons were hesitant to receive COVID-19 vaccination.2Kaiser Family FoundationCoronavirus (COVID-19). KFF COVID-19 vaccine monitor: December 2020. Kaiser Family Foundation, San Francisco, CA2020Google Scholar To examine perceptions toward COVID-19 vaccine and intentions to be vaccinated, in September and December 2020, CDC conducted household panel surveys among a representative sample of U.S. adults. From September to December, vaccination intent (defined as being absolutely certain or very likely to be vaccinated) increased overall (from 39.4% to 49.1%); the largest increase occurred among adults aged ≥65 years. If defined as being absolutely certain, very likely, or somewhat likely to be vaccinated, vaccination intent increased overall from September (61.9%) to December (68.0%). Vaccination nonintent (defined as not intending to receive a COVID-19 vaccination) decreased among all adults (from 38.1% to 32.1%) and among most sociodemographic groups. Younger adults, women, non-Hispanic Black (Black) persons, adults living in nonmetropolitan areas, and adults with lower educational attainment, with lower income, and without health insurance were most likely to report lack of intent to receive COVID-19 vaccine. Intent to receive COVID-19 vaccine increased among adults aged ≥65 years by 17.1 percentage points (from 49.1% to 66.2%), among essential workers by 8.8 points (from 37.1% to 45.9%), and among adults aged 18–64 years with underlying medical conditions by 5.3 points (from 36.5% to 41.8%). Although confidence in COVID-19 vaccines increased during September–December 2020 in the United States, additional efforts to tailor messages and implement strategies to further increase the public’s confidence, overall and within specific subpopulations, are needed. Ensuring high and equitable vaccination coverage across all populations is important to prevent the spread of COVID-19 and mitigate the impact of the pandemic. The Advisory Committee on Immunization Practices (ACIP) has issued interim recommendations for COVID-19 vaccine allocation, with initial limited supplies of vaccines recommended for healthcare personnel and residents of long-term care facilities (phase 1a); frontline essential workers and persons aged ≥75 years (phase 1b); and persons aged 65–74 years, persons aged 16–64 years at high risk for severe COVID-19 illness because of underlying medical conditions,* and other workers in essential and critical infrastructure sectors† not included in phases 1a and 1b (phase 1c).3Dooling K McClung N Chamberland M et al.The Advisory Committee on Immunization Practices’ interim recommendation for allocating initial supplies of COVID-19 vaccine—United States, 2020.MMWR Morb Mortal Wkly Rep. 2020; 69 (https://doi.org/10.15585/mmwr.mm6949e1.

During September 3–October 1, CDC conducted a probability-based Internet panel survey (IPSOS KnowledgePanel)§ of a nationally representative sample of 3541 U.S. adult panelists aged ≥18 years to assess intent to receive a COVID-19 vaccine and perceptions about the vaccine.5Nguyen KH Kahn K Hoehner J et al.AdultVaxView: COVID-19 vaccination intent, perceptions, and reasons for not vaccinating among groups prioritized for early vaccination, United States, September 2020. US Department of Health and Human Services, CDC, Atlanta, GA2021Google Scholar During December 18–20, CDC sponsored questions on two probability-based household panel omnibus surveys (IPSOS KnowledgePanel¶ and NORC Amerispeak****) administered to 2033 panelists (approximately 1000 panelists each) to reassess COVID-19 vaccination intent and related perceptions.†† This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.§§ The same questions about COVID-19 vaccine intentions, perceptions, and reasons for not receiving a COVID-19 vaccine were asked in the September and December surveys. However, most respondents were different for each survey; only 123 panelists (3.5%) completed both the September and December IPSOS survey. Intent was assessed by response to the following question: “If a vaccine against COVID-19 were available today at no cost, how likely would you be to get it?” Response options were “absolutely certain,” “very likely,” “somewhat likely,” and “not likely.” Respondents who answered “absolutely certain” or “very likely” to receive a COVID-19 vaccination were defined as intending to be vaccinated, and respondents who answered “not likely” were defined as not intending to be vaccinated. Vaccination intentions and related perceptions were stratified by the following three mutually exclusive groups representing the ACIP priorities for initial doses of COVID-19 vaccine after healthcare providers and long-term care residents: (1) essential workers,¶¶ (2) adults aged 18–64 years with underlying medical conditions, and (3) adults aged ≥65 years.***** Sample size for the December surveys was not large enough to stratify the analysis by age group (65–74 years vs. ≥75 years) or essential worker subgroups (healthcare personnel, other frontline essential workers, and other non-frontline essential workers). Analyses were also conducted to provide estimates among all adults and among adults not included in the initial ACIP priority groups (aged 18–64 years with no underlying medical conditions and who were not essential workers). Responses to questions on intent, perceptions, and reasons for not getting vaccinated were examined by sociodemographic characteristics and priority groups for the September and December surveys. Because of similar sampling methods and characteristics of respondents, the averages of the estimates from the two December surveys were calculated, and the difference between the September survey and the average of the December surveys was determined using t-tests. All surveys were weighted to ensure representativeness of the U.S. population, and all analyses were conducted using SAS-callable SUDAAN (version 11.0; RTI International). From September to December, the proportion of adults reporting intent to receive COVID-19 vaccine as absolutely certain or very likely increased significantly by 9.7% points (from 39.4% to 49.1%), and the proportion reporting nonintent decreased by 6.0% points (from 38.1% to 32.1%) (Table 1). Among priority groups, intent increased by 17.1 percentage points among adults aged ≥65 years (from 49.1% to 66.2%), by 8.8% points among essential workers (from 37.1% to 45.9%), and by 5.3% points among adults aged 18–64 years with underlying medical conditions (from 36.5% to 41.8%) (Supplementary Figure, https://stacks.cdc.gov/view/cdc/101583).TABLE 1COVID-19 vaccination intent among surveyed adults, by vaccination priority group — United States, September and December 2020CharacteristicWeighted % (95% CI)IPSOS, Sep 2020*IPSOS KnowledgePanel Survey, fielded September 3–October 1.

Vaccination nonintent differed by sociodemographic characteristics and decreased across most socioeconomic groups from September to December (Table 2). For example, nonintent decreased by 10.3 percentage points among adults aged 50–64 years and by 11.1 percentage points among adults aged ≥65 years. Although nonintent was higher among women, nonintent among both women and men decreased by 6.0 percentage points between September and December. Nonintent was highest among Black persons in September (56.1%) and December (46.5%) compared with other racial/ethnic groups, with the difference between months (–9.6) not statistically significant. Nonintent was higher among adults with lower educational attainment and lower income but decreased across most education and income categories: among adults with a high school diploma or less, nonintent decreased 7.9% points, and in households with annual incomes of $35 000–$49 999, nonintent decreased by 10.8% points. Vaccination nonintent also decreased in metropolitan statistical areas††† by 6.7% points and among adults in all regions of the United States, except the Northeast, including decreases of 8.3% points in the South, 6.8 in the Midwest, and 6.8 in the West. In December, nonintent was highest among persons without health insurance (44.5%), compared with those who had private health insurance (30.7%) and public health insurance (29.6%), and was similar in September and December.TABLE 2Prevalence of intent not to receive COVID-19 vaccine, by selected characteristics — United States, September and December 2020CharacteristicWeighted % (95% CI)IPSOS, Sep 2020*IPSOS KnowledgePanel Survey, fielded September 3–October 1.
