Abstract
Background
Achieving high COVID-19 vaccination rates among employees is necessary to prevent outbreaks in health care settings. The goal of the study was to produce actionable and timely evidence about factors underlying the intention and decisions to obtain the COVID-19 vaccine by employees.Methods
The study was conducted from December 2020 - May 2021 with employees from a VA health care system in Southeastern US. The study used a convergent mixed methods design comprising two main activities: a cross-sectional survey conducted prior to COVID-19 vaccine distribution, and semi-structured interviews conducted 4-6 months after vaccine distribution. Data were collected about participant characteristics, vaccination intention prior to distribution, vaccination decision post-distribution, determinants of vaccination intention and decision, activating factors, sources of information and intervention needs. Data from the survey and interviews were analyzed separately and integrated narratively in the discussion.Results
Prior to vaccine distribution, 77% of employees wanted to be vaccinated. Post vaccine distribution, we identified 5 distinct decision-making groups: 1) vaccine believers who actively sought vaccination and included those sometimes described as "immunization advocates", 2) go along to get along (GATGA) individuals who got vaccinated but did not actively seek it, 3) cautious acceptors who got the COVID-19 vaccine after some delay, 4) fence sitters who remained uncertain about getting vaccinated, and 5) vaccine refusers who actively rejected the COVID-19 vaccine. Participants identifying with Black or multiple races were more likely to express hesitancy in their vaccination intention.Conclusion
The findings of our study highlight distinct decision-making profiles associated with COVID-19 vaccination among employees of a VA health care system, and provide tailored recommendations to reduce vaccine hesitancy in this population.Type

Lavanya Vasudevan
Lavanya Vasudevan is an adjunct associate professor at the Global Health Institute at Duke University. Her research focuses on studying the timeliness of vaccinations, identifying vaccination barriers, and understanding the role of misinformation in driving vaccine hesitancy. In addition, she works on developing and evaluating novel interventions, including those that leverage digital health technologies, for health information or service delivery. In her research, Dr. Vasudevan seeks to study and alleviate the complex challenges with vaccination delivery and uptake in low resource settings and in populations experiencing health disparities. In the context of these challenges, Dr. Vasudevan is interested in the use of multidisciplinary collaborations, mixed methods and implementation science frameworks. Dr. Vasudevan completed her doctoral training in molecular biology and genetics at Cornell University and received her Master’s degree in public health from the Johns Hopkins Bloomberg School of Public Health. Dr. Vasudevan is Certified in Public Health by the National Board of Public Health Examiners.
