Abstract

Nursing home residents and health care personnel (HCP) are at increased risk for exposure to influenza; in addition, residents of nursing homes who acquire influenza are at increased risk for severe disease. The Advisory Committee on Immunization Practices recommends routine annual seasonal influenza vaccination for persons without contraindications, including HCP and those at increased risk for severe influenza. Nursing homes report influenza vaccination among residents and HCP to CDC’s National Healthcare Safety Network. This report describes influenza vaccination coverage among nursing home residents and HCP working in nursing homes during the 2024–25 influenza season (October 1, 2024–March 31, 2025). At the end of the 2024–25 influenza season, influenza vaccination coverage was 61.3% among nursing home residents and 42.1% among HCP who work in nursing homes; coverage among HCP varied by employment type. This study is the first comprehensive, national assessment of influenza vaccination coverage among nursing home residents and HCP who work in nursing homes in the United States. Monitoring of influenza vaccination coverage in this population at high risk for influenza exposure and severe influenza disease, along with implementation of a combination of influenza vaccination, administration of influenza antiviral medications, and other recommended practices to control the spread and severity of influenza in nursing home settings, can help protect nursing home residents and HCP against severe influenza-associated outcomes.

Introduction

Each year, approximately 8% of the U.S. population becomes ill with influenza, a contagious respiratory illness caused by viruses that infect the nose, throat, and lungs and can lead to death. Persons who live and work in congregate settings such as nursing homes are at increased risk for exposure to influenza virus, and nursing home residents are at increased risk for complications from severe influenza (1). Influenza vaccination reduces the risk for severe influenza potentially leading to hospitalization (2) and can prevent influenza infection among nursing home residents (3). Increased influenza vaccination coverage among health care personnel (HCP) working in nursing homes has been associated with decreased mortality among residents (4). Vaccinating HCP against influenza can also reduce absenteeism among HCP (5), which might improve the quality of resident care by improving staffing stability (6). The Advisory Committee on Immunization Practices (ACIP) recommends annual seasonal influenza vaccination for persons without contraindications, including HCP and persons at increased risk for severe influenza disease (7). The Centers for Medicare & Medicaid Services (CMS) requires nursing homes to report influenza vaccination coverage both among nursing home residents and HCP working in nursing homes to CDC’s National Healthcare Safety Network (NHSN). This report analyzes seasonal influenza vaccination coverage among residents and HCP at nursing homes during the 2024–25 influenza season (October 1, 2024–March 31, 2025).

Data Source

HCP employment categories. Beginning with the 2022–23 influenza season, nursing homes in the United States have been required by CMS to report influenza vaccination among HCP to CDC’s NHSN at the end of each season. NHSN collects information on types of HCP employment and categorizes them into the following groups: 1) employees (all persons receiving a paycheck directly from the reporting facility); 2) licensed independent practitioners (physicians, advanced practice nurses, and physician assistants who are affiliated with the reporting facility but not directly employed by it, including postresidency fellows not on the facility’s payroll); and 3) students, trainees, or volunteers (medical, nursing, or other health professional students, interns, medical residents, or volunteers aged ≥18 years who are affiliated with but not directly employed by the facility). Employment type is determined without regard to clinical responsibility or patient contact.

Influenza vaccination coverage among HCP. To measure influenza vaccination coverage, facilities report an annual number of HCP working in the facility for ≥1 day during an influenza season (October 1–March 31) and the number of HCP who 1) received influenza vaccination, 2) had a medical contraindication to influenza vaccination, 3) declined vaccination, and 4) had unknown influenza vaccination status. HCP who were vaccinated outside of the nursing home facility and who provided written documentation of vaccination were categorized as vaccinated; those who reported having received a vaccination but who did not provide documentation were categorized as having an unknown vaccination status. Data collected for the 2024–25 influenza season were used in this analysis.

Influenza vaccination coverage among nursing home residents. Since October 2023, nursing homes have had the option to report weekly influenza vaccination coverage among nursing home residents; in January 2025, CMS began requiring nursing homes to report these data. Nursing homes report the number of residents who occupied a bed at the facility for ≥1 day during the week of data collection and the cumulative number of residents who received the current season’s influenza vaccine. Cumulative coverage data reported by nursing homes for the week of March 30, 2025, were used for analysis.

Facility characteristics. The following facility characteristics were obtained from the CMS provider data catalog (an official CMS open data source available to the public) and used for analysis: 1) facility ownership type (nonprofit, government, and for profit), 2) government insurance certification (Medicare, Medicaid, and dual Medicare and Medicaid), and 3) facility size tertile defined by the number of CMS-certified beds in the facility (small [fewer than 82], medium [82–120], and large [more than 120]).

Data Analysis

Overall resident and HCP influenza vaccination coverage. Data reported to NHSN from CMS-certified nursing homes in all 50 U.S. states and the District of Columbia were included in this investigation. Analysis was limited to facilities that reported influenza vaccination for both residents and HCP. Pooled and facility-level influenza vaccination coverage levels were calculated for HCP and residents. Pooled influenza vaccination coverage among HCP was calculated as the total number of HCP who had received influenza vaccine, divided by the total number of HCP working in a nursing home for ≥1 day during the influenza season. HCP with a reported medical contraindication to influenza vaccination (0.89% of all HCP) were subtracted from the denominator and excluded from analysis. Pooled influenza vaccination coverage among residents was calculated as the total number of residents who received a 2024–25 influenza vaccine divided by the total number of residents living in nursing homes during the week of data collection. Facility-level influenza vaccination coverage among HCP and residents was calculated as the number of HCP or residents who received a 2024–25 influenza vaccine divided by the number of HCP or residents, respectively, in that nursing home.

Stratified subgroup analyses. To illustrate facility-level vaccination coverage variation, facility-level influenza vaccination coverage at the 25th, 50th, and 75th percentile distributions within each subgroup were reported. Results were further stratified by facility insurance certification (Medicaid, Medicare, or dual); ownership (nonprofit, government, or for profit); National Center for Health Statistics county-level urbanicity (large central metropolitan, large fringe metropolitan, medium metropolitan, small metropolitan, micropolitan, or noncore)*; facility size tertile; state; and U.S. region.† Pooled vaccination coverage for HCP was also stratified by employment category (employee; independent licensed practitioner; and student, trainee, or volunteer). All analyses were conducted using SAS (version 9.4; SAS Institute), and maps were generated using R (version 4.4.1; R Foundation). This activity was reviewed by CDC, deemed not research, and conducted consistent with applicable federal law and CDC policy.§

Influenza Vaccination Coverage Among Nursing Home Residents

Among approximately 1.2 million residents of the 13,299 nursing homes included in this analysis, the overall pooled influenza vaccination coverage was 61.3%, and the median facility-level coverage was 67.0% (IQR = 53.0%–78.6%) (

Influenza Vaccination Coverage Among HCP Working in Nursing Homes

Among approximately 2.1 million HCP working in the 13,299 nursing homes included in this analysis, the overall pooled influenza vaccination coverage was 42.1%, and the median facility-level HCP coverage was 35.1% (IQR = 16.8%–63.8%). Vaccination coverage was highest among HCP working in nonprofit nursing homes (52.6%) and lowest among those working in for-profit nursing homes (38.3%) (

Discussion

During the 2024–25 influenza season, approximately three in five nursing home residents (61.3%) and two in five HCP working in nursing homes (42.1%) received an influenza vaccine. The 2024–25 season was the first during which nursing homes were required to report influenza vaccination coverage among residents. Influenza vaccination coverage among nursing home residents was lower than that among the general population aged ≥75 years during the same seasonal period (75.6%). This difference in vaccination coverage between these two populations might be partially due to differences in how the data were collected but also might indicate barriers to vaccination that are unique to nursing home residents.

Although facility-level characteristics associated with influenza vaccination varied between residents and HCP, coverage among both populations was highest in the Northeast and among small facilities. Influenza vaccination coverage among nursing home residents was highest among facilities with Medicaid certification only, which are also known as long-stay nursing homes. This finding is consistent with other reports indicating that influenza vaccination coverage is higher among residents of long-stay nursing homes than among residents of short-stay (8). To prevent the spread of influenza in nursing homes, considering these facility-level characteristics could be beneficial during the implementation of influenza vaccination activities in conjunction with other testing, treatment, and infection prevention and control measures.

Influenza vaccination coverage among HCP working in nursing homes during the 2024–25 influenza season was lower than that during the 2023–24 influenza season (45.4%); coverage also remained substantially lower than the 80.7% reported among HCP in acute care hospitals for 2023–24 season (9). A recent study found that lack of confidence in the influenza vaccine among HCP in U.S. nursing homes in average- and low-coverage states was driven by concerns about potential side effects, vaccine effectiveness, and the necessity for vaccination. The same study found that influenza vaccination might be increased through interventions such as offering educational campaigns, on-site vaccination, and vaccine recommendations by trusted personnel (10). These findings underscore the possibility that influenza vaccination among HCP at nursing homes could be increased by implementing currently recommended strategies and tailoring approaches by employee category.

Limitations

The findings in this report are subject to at least three limitations. First, because of differences in data collection, the calculation of influenza vaccination coverage among HCP included all HCP eligible to work in the facility at any time during the influenza season, whereas the calculation for vaccination among residents only included residents in the facility during the week of data collection. Therefore, these denominators and the resulting calculations cannot be directly compared. Second, the requirement that HCP who received influenza vaccination outside of the nursing home facility provide written documentation to be categorized as vaccinated might have resulted in underestimates of influenza vaccination coverage among HCP, especially those not directly employed by the facility. Finally, this analysis was conducted using aggregate data reported to NHSN at the facility level. Therefore, vaccination coverage could not be stratified by individual covariates that might enable an assessment of differences in coverage by factors such as age and comorbidities.

Implications for Public Health Practice

This analysis found that during the 2024–25 influenza season, influenza vaccination coverage among HCP working in nursing homes was lower than coverage reported for the previous season. This was the first season for which comprehensive national data on influenza vaccination among residents in nursing homes were available. To prevent the spread of influenza in nursing homes, these facilities are recommended to implement influenza vaccination in combination with other practices for controlling outbreaks, such as influenza testing, proven infection prevention and control measures, antiviral treatment, and antiviral chemoprophylaxis. In addition, influenza vaccination of HCP has been associated with reduced mortality among nursing home residents (4) and is an important strategy for ensuring stability of staffing in nursing homes and providing optimal care to residents (5,6).
