Abstract
<jats:p>Many studies identified factors associated with vaccination intention and hesitancy, but factors associated with vaccination promptness and the effect of vaccination intention on vaccination promptness are unknown. This study identified factors associated with COVID-19 vaccination promptness and evaluated the role of vaccination intention on vaccination promptness in 1223 participants in a community-based longitudinal cohort study (June 2020 to December 2021). Participants answered questions regarding COVID-19 vaccination intention, vaccination status, and reasons for not receiving a vaccine. The association of baseline vaccine hesitancy with vaccination was assessed by the Kaplan–Meier survival analysis. Follow-up analyses tested the importance of other variables predicting vaccination using the Cox proportional hazards model. Older age was associated with shorter time to vaccination (HR = 1.76 [1.37–2.25] 85-year-old versus 65-year-old). Lower education levels (HR = 0.80 [0.69–0.92]), household incomes (HR = 0.84 [0.72–0.98]), and baseline vaccination intention of ‘No’ (HR = 0.16 [0.11–0.23]) were associated with longer times to vaccination. The most common reasons for not being vaccinated (N = 58) were vaccine safety concerns (n = 33), side effects (n = 28), and vaccine effectiveness (n = 25). Vaccination campaigns that target populations prone to hesitancy and address vaccine safety and effectiveness could be helpful in future vaccination rollouts.</jats:p>

Coralei Neighbors
Coralei Neighbors, MS, is a third-year Ph.D. candidate in Population Health Sciences at the Duke University School of Medicine. Her research integrates infectious disease surveillance, economic evaluation, and policy analysis to inform evidence-based and equitable vaccine strategies. Her work sits at the intersection of infectious disease epidemiology, health economics, and global health policy, applying decision-analytic modeling and surveillance data to support population-level decision-making and resource allocation.
Coralei holds a Bachelor of Science in Health Science Studies from Baylor University and a Master of Science in Global Health from Duke University. She is currently pursuing graduate certificates in East Asian Studies, International Development Policy, and College Teaching, enhancing the global relevance and instructional impact of her work.
Her research contributes to advancing approaches that translate economic and epidemiologic evidence into actionable policy insights. She aims to support policymakers in developing effective, sustainable, and equity-driven immunization strategies. Long term, she aspires to contribute to global health systems strengthening through economic evaluation, decision-analytic modeling, and policy engagement.

Analytic Interests.
1) Issues in the Design of Medical Experiments: I explore the use of reliability/generalizability models in experimental design. In addition to incorporation of reliability, I study powering longitudinal trials with multiple outcomes and substantial missing data using Mixed models.
2) Issues in the Analysis of Repeated Measures Designs & Longitudinal Data: Use of Hierarchical Linear Models (HLM) or Mixed Models in modeling trajectories of multiple variables over time (e.g., physical and cognitive functioning and Blood Pressure). My current work involves methodologies in simultaneous estimation of trajectories for multiple variables within and between domains, modeling co-occuring change.
Areas of Substantive interest: (1) Experimental design and analysis in gerontology and geriatrics, and psychiatry,
(2) Multivariate repeated measures designs,

Research Description
General Focus: Clinical investigation the process and treatment of acute and chronic coronary artery disease and systems issues for delivery of care to patients with these illnesses. Particular interests include management of patients with chest pain and unstable angina, evaluation of the use of biochemical markers other than CK-MB for diagnosis and risk stratification in these patients, issues related to coronary artery disease in women, and systems issues regarding optimizing the process of delivery of care to patients with acute and chronic coronary artery disease. Finally, I have a strong interest in defining the genetic contribution to development of coronary artery disease.
