Summary
What is already known about this topic?
U.S. adult vaccination coverage data are limited, especially among populations lacking primary health care access.
What is added by this report?
In a multicenter emergency department (ED) survey of vaccine knowledge, self-reported vaccination status, and willingness to receive vaccines if offered in an ED, 49.4% of non–critically ill adult participants had not heard of at least one CDC-recommended vaccine, and 85.9% had missed one or more. Overall, 46.4% of participants who were not up to date with recommended vaccines said they would accept one or more missing vaccines if offered during their ED visit; 86.7% of those participants said they would accept all missing vaccines.
What are the implications for public health practice?
EDs could be explored as settings to offer vaccination screening, recommendations, counseling, and referrals to increase vaccination coverage among underserved populations.
Abstract
Current models of vaccination coverage screening and surveillance might miss underserved populations whose only health care access occurs in emergency departments (EDs). During April–December 2024, a survey of non–critically ill adult patients evaluated in 10 EDs in eight U.S. cities across five states was conducted to ascertain patients’ vaccination knowledge, self-reported vaccination coverage, and willingness to receive vaccines in an ED. Among 4,326 patients approached by the research team, 3,285 (75.9%) agreed to participate. Non-Hispanic Black or African American (Black), non-Hispanic White, and Hispanic or Latino (Hispanic) persons each accounted for approximately 30% of participants; 17.9% spoke Spanish as their primary language; 7.8% had unstable or marginal housing; and 21.0% lacked a source of primary health care. Approximately one half (49.4%) had not heard of one or more CDC-recommended vaccines for their age group, and 85.9% had not received one or more of the recommended vaccines. Factors associated with not being up to date with recommended vaccinations included non-Hispanic Black race and ethnicity (adjusted odds ratio [aOR] = 1.93; 95% CI = 1.32–2.85), lack of primary health care (aOR = 2.91; 95% CI = 1.74–5.13), and lack of health insurance (aOR = 3.01; 95% CI = 1.27–8.82). Among 2,821 participants who were not up to date with recommended vaccines, 46.4% said that they would accept one or more missing vaccines if they could be provided during their ED visit, and 86.7% of these persons said they would accept all missing vaccines. The primary reasons for missed vaccine doses were that the participant was unaware of or had not been offered the vaccines. EDs could be explored as additional sites to offer vaccination screening, recommendations, counseling, and referrals to increase vaccination coverage among underserved populations.
