Timely Second-Dose Completion of mRNA COVID-19 Vaccination at Community-Based and Mobile Vaccine Clinics in Maryland

Abstract

To assess factors associated with timely second-dose completion, we analyzed COVID-19 vaccine data from community-based and mobile vaccine clinics in Maryland. Overall, 85.3% of patients received a timely second dose. Factors associated with a timely second dose included Latino ethnicity (adjusted odds ratio [AOR] = 1.5; 95% confidence interval [CI] = 1.1, 2.0) and receipt of the first dose at community-based vaccine clinics (AOR = 2.1; 95% CI = 1.8, 2.5). Future health initiatives for underserved communities should focus on establishing vaccine clinics in trusted community spaces with culturally sensitive support.
