Approximately 60 million persons in the United States live in rural counties, representing almost one fifth (19.3%) of the population.* In September 2020, COVID-19 incidence (cases per 100,000 population) in rural counties surpassed that in urban counties (1). Rural communities often have a higher proportion of residents who lack health insurance, live with comorbidities or disabilities, are aged ≥65 years, and have limited access to health care facilities with intensive care capabilities, which places these residents at increased risk for COVID-19-associated morbidity and mortality (2,3). To better understand COVID-19 vaccination disparities across the urban-rural continuum, CDC analyzed county-level vaccine administration data among adults aged ≥18 years who received their first dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine, or a single dose of the Janssen COVID-19 vaccine (Johnson & Johnson) during December 14, 2020-April 10, 2021 in 50 U.S. jurisdictions (49 states and the District of Columbia [DC]). Adult COVID-19 vaccination coverage was lower in rural counties (38.9%) than in urban counties (45.7%) overall and among adults aged 18-64 years (29.1% rural, 37.7% urban), those aged ≥65 years (67.6% rural, 76.1% urban), women (41.7% rural, 48.4% urban), and men (35.3% rural, 41.9% urban). Vaccination coverage varied among jurisdictions: 36 jurisdictions had higher coverage in urban counties, five had higher coverage in rural counties, and five had similar coverage (i.e., within 1%) in urban and rural counties; in four jurisdictions with no rural counties, the urban-rural comparison could not be assessed. A larger proportion of persons in the most rural counties (14.6%) traveled for vaccination to nonadjacent counties (i.e., farther from their county of residence) compared with persons in the most urban counties (10.3%). As availability of COVID-19 vaccines expands, public health practitioners should continue collaborating with health care providers, pharmacies, employers, faith leaders, and other community partners to identify and address barriers to COVID-19 vaccination in rural areas (2).

Approximately 60 million persons in the United States live in rural counties, representing almost one fifth (19.3%) of the population.* In September 2020, COVID-19 incidence (cases per 100,000 population) in rural counties surpassed that in urban counties (1) . Rural communities often have a higher proportion of residents who lack health insurance, live with comorbidities or disabilities, are aged ≥65 years, and have limited access to health care facilities with intensive care capabilities, which places these residents at increased risk for COVID-19-associated morbidity and mortality (2, 3) . To better understand COVID-19 vaccination disparities across the urban-rural continuum, CDC analyzed county-level vaccine administration data among adults aged ≥18 years who received their first dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine, or a single dose of the Janssen COVID-19 vaccine (Johnson & Johnson) during December 14, 2020-April 10, 2021 in 50 U.S. jurisdictions (49 states and the District of Columbia [DC] ). Adult COVID-19 vaccination coverage was lower in rural counties (38.9%) than in urban counties (45.7%) overall and among adults aged 18-64 years (29.1% rural, 37.7% urban), those aged ≥65 years (67.6% rural, 76.1% urban), women (41.7% rural, 48.4% urban), and men (35.3% rural, 41.9% urban). Vaccination coverage varied among jurisdictions: 36 jurisdictions had higher coverage in urban counties, five had higher coverage in rural counties, and five had similar coverage (i.e., within 1%) in urban and rural counties; in four jurisdictions with no rural counties, the urban-rural comparison could not be assessed. A larger proportion of persons in the most rural counties (14.6%) traveled for vaccination to nonadjacent counties (i.e., farther from their county of residence) compared with persons in the most urban counties (10.3%). As availability of COVID-19 vaccines expands, public health practitioners should continue collaborating with health care providers, pharmacies, employers, faith leaders, and other community partners to identify and address barriers to COVID-19 vaccination in rural areas (2) .

Data on COVID-19 vaccine doses administered in the United States are reported to CDC by jurisdictions, pharmacies, and * https://www.census.gov/library/stories/2017/08/rural-america.html federal entities through immunization information systems (IISs), † the Vaccine Administration Management System, § or direct data submission. ¶ Adults aged ≥18 years with a valid county of residence in one of 49 states or DC who received their first COVID-19 vaccine dose** during December 14, 2020-April 10, 2021, and whose data were reported to CDC by April 15, 2021, were included in the analysis. † † COVID-19 vaccine doses administered to persons living in Hawaii and in eight counties in California with <20,000 residents were excluded, because these states have data-sharing restrictions on county-level information reported to CDC. Vaccine doses administered to persons living in U.S. territories were also excluded because territorial jurisdictional divisions could not be mapped to urban-rural classifications at the county level.

First doses of COVID-19 vaccine were matched by county of residence to one of six urban-rural categories according to the 2013 National Center for Health Statistics (NCHS) urban-rural classification scheme. To further classify counties into two categories (urban versus rural), four of these six categories (large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan) were combined into urban areas, and two (micropolitan and noncore) were combined into rural areas (4).

Vaccination coverage for adults aged ≥18 years was calculated overall and by age group (18-64 and ≥65 years), sex, † IISs are confidential, computerized, population-based systems that collect and consolidate vaccination data from providers in 64 jurisdictions nationwide and can be used to track administered vaccines and measure vaccination coverage. jurisdiction, and two-and six-level urban-rural classification. Coverage by race and ethnicity was not calculated because information on race and ethnicity was missing for 40% of data. Population size was obtained by county, age group, and sex from the U.S. Census Bureau's 2019 Population Estimates Program (5) . Because only the first dose of a 2-dose vaccination series or the only dose for a single-dose vaccine were analyzed, the total number of doses allowed per county was capped at the population size of the county. § § The percentage of persons who traveled outside their county of residence for vaccination was calculated at the national level and stratified by jurisdiction for both the two-and six-level urban-rural classifications. Tests for statistical significance were not conducted because the data represent the U.S. population (minus Hawaii and eight counties in California) and were not based on population samples. First-dose COVID-19 vaccination coverage was lower in rural than in urban counties for adults overall (38.9% rural, 45.7% urban) (Table) ; for adults aged 18-64 years (29.1% rural, 37.7% urban) and for those aged ≥65 years (67.6% rural, 76.1% urban); for women (41.7% rural, 48.4% urban); and for men (35.3% rural, 41.9% urban). Among jurisdictions, coverage varied by urban-rural classification; in 36 (72%) jurisdictions, coverage was higher in urban counties, in five (10%) coverage was higher in rural counties, and in five (10%) coverage was similar (i.e., within 1%) in both urban and rural counties. Vaccination coverage by urban-rural classification could not be calculated for four jurisdictions that had no rural counties.

Overall, 67.1% of vaccinated persons were vaccinated in their county of residence and 98.3% in their state of residence. The proportion of persons who traveled outside their county of residence for vaccination varied by jurisdiction, based on the two-level urban-rural classification ( Figure 1 ). Analysis using the six-level urban-rural classification found that a larger proportion of persons in large fringe metropolitan counties (i.e., suburban areas) and noncore counties (i.e., the most rural areas) traveled to nonadjacent counties (i.e., farther from their county of residence) for vaccination (13.9% and 14.6%, respectively) compared with persons in the most urban counties (10.3%) ( Figure 2 ).

Among most U.S. jurisdictions analyzed, COVID-19 vaccination coverage was lower overall, among all age groups, and among men and women in rural compared with urban counties. Coverage among adults aged ≥65 years was higher than among younger adults in both rural and urban areas, likely because of vaccine eligibility criteria that prioritized § § For statistical analysis, the number of doses allowed per county was capped at population size minus one for a maximum vaccination coverage of 100%.

older adults earlier in the implementation of the vaccination program before vaccination was expanded to other age groups.

Notably, vaccination coverage among women in both urban and rural areas was higher than that among men, possibly because of the increased likelihood of women seeking and using preventive care services (6), or women working in sectors that were prioritized for early vaccination, such as health care and education. ¶ ¶ Because residents of rural communities are at increased risk for severe COVID-19-associated illness and death (2, 3) , vaccination disparities between urban and rural areas might hinder efforts to reduce morbidity and mortality from COVID-19 nationally. Travel outside county of residence was used as a marker of potential vaccine access difficulties that might be exacerbated in rural areas with sparse vaccination sites. Analysis using the six-level urban-rural classification identified that a higher percentage of persons in the most rural counties traveled to nonadjacent counties for vaccination compared with those in the most urban counties, which might be related to challenges with vaccine access and the dearth of pharmacies in some rural areas (7) . In addition, more persons in suburban (i.e., large fringe metropolitan) areas traveled outside their county of residence for vaccination; the reasons for this are unclear.

Although vaccination coverage was higher in urban counties compared with that in rural counties in most jurisdictions, five jurisdictions had similar vaccination rates between urban and rural counties and in another five, the rate in rural counties surpassed that of urban counties. Jurisdictional characteristics reported in news media that might have contributed to increased vaccination coverage in rural areas included implementing tailored approaches based on local needs, partnering with local community-based organizations and faith leaders, and engaging with underserved populations directly and through partners.*** , † † † Local jurisdictions are collaborating with CDC to improve access to COVID-19 vaccines in rural areas by identifying and addressing barriers to vaccination. CDC is also using multiple channels to distribute vaccines, such as federal partners (e.g., the Indian Health Service and the Health Resources and Services Administration) and the Federal Retail Pharmacy program. § § § Vaccine hesitancy in rural areas is a major barrier that public health practitioners, health care providers, and local partners need to address to achieve vaccination equity.

Among the rural respondents, 45% of younger adults (aged 18-64 years) stated that they would "definitely not" get a vaccine compared with 8% of older adults (aged 60-69 years) (8) . Rural residents who reported that they would "definitely not" get a vaccine were more likely to report not having a college degree and earning <$40,000 per year (8) . Notably, 86% of rural residents report they trust their own health care providers for information on COVID-19 vaccines, which highlights the importance of public health practitioners working with established outpatient health care systems in rural areas (9) . Through its Vaccinate with Confidence initiative, To further classify counties into two categories (urban versus rural), four of these six categories were combined into urban areas (large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan) and two were combined into rural areas (micropolitan and noncore). § Excludes doses with state of residence reported as Hawaii, a territory, an island, or a county of residence in California with population <20,000.

CDC continues to support rural jurisdictions and local partners in their efforts to improve access to, and bolster trust and confidence in, COVID-19 vaccines. ¶ ¶ ¶ The findings in this report are subject to at least five limitations. First, vaccination coverage is not representative of the entire United States, because county of residence was missing for 9.2% of persons.**** Second, each jurisdiction prioritized population subgroups for vaccination differently, which might have also contributed to vaccination coverage differences between urban and rural populations. Third, COVID-19 vaccine supply changed substantially during the observed time period, and persons may have been willing to travel farther for vaccination at the beginning of this time period when vaccine supplies were low, compared with later time periods. Fourth, race and ethnicity were unknown for approximately 40% of persons with available county information; therefore, vaccination coverage could not be calculated on the basis of race and ethnicity. Improved data completeness is critical to measure and address racial and ethnic disparities in vaccination coverage. Finally, the NCHS urban-rural classification was developed in 2013, and counties that were classified as rural in 2013 might not be classified as rural during 2020-2021.

What is already known about this topic?

Residents of rural communities are at increased risk for severe COVID-19-associated morbidity and mortality. In September 2020, COVID-19 incidence (cases per 100,000 population) in rural counties surpassed that in urban counties.

What is added by this report?

COVID-19 vaccination coverage was lower in rural counties (38.9%) than in urban counties (45.7%); disparities persisted among age groups and by sex.

What are the implications for public health practice?

Disparities in COVID-19 vaccination access and coverage between urban and rural communities can hinder progress toward ending the pandemic. Public health practitioners should collaborate with health care providers, pharmacies, employers, faith leaders, and other community partners to identify and address barriers to COVID-19 vaccination in rural areas.
