COVID-19 has caused excessive morbidity and mortality worldwide. COVID-19 vaccines, including the two mRNA vaccines, were developed to help mitigate COVID-19 and to move society towards herd immunity. Despite the strong efficacy and effectiveness profile of these vaccines, there remains a degree of vaccine hesitancy among the population. To better understand hesitancy associated with COVID-19 vaccines and to delineate between those who are vaccine acceptors, vaccine refusers, and the moveable middle, we conducted a cross-sectional survey to understand respondents' decision to receive, or not, a COVID-19 vaccine at the onset of mRNA vaccine availability in Central Texas. A total of 737 individuals responded, with 685 responses classified to one of eight domains: A: End to the Pandemic (n = 48); B: Trust in Medical Community (n = 27); C: Illness-Focused Perceptions (n = 331); D: Social Motivation (n = 54); E: Vaccine-Focused Perceptions (n = 183); F: Knowledge Gap (n = 14); G: Underlying Health Concern (n = 9); and H: Undecided (n = 19). Vaccine acceptors (n = 535) were primarily represented in domains A-E, while vaccine refusers (n = 26) were primarily represented in domains C, E, G, and H. The moveable middle (n = 124) was primarily represented by domains C-H. These findings show clear delineations between vaccine acceptors, vaccine refusers, and the moveable middle across eight domains that can assist public health professionals in addressing vaccine hesitancy.
