Objective: To investigate disparities in coronavirus disease 2019 (COVID-19) vaccine awareness and vaccination rates according to workplace characteristics. Methods: A survey conducted from August to November 2021 among 106 dental hygienists was used to investigate COVID-19 vaccination rates, general and workplace characteristics, COVID-19-related workplace characteristics and awareness. T-tests and ANOVA were used to determine differences in awareness based on general and workplace characteristics, while chi-square analysis was used to examine differences in inoculation rates (α=0.05). Results: 86 participants (81.1%) had been vaccinated. Vaccination was recommended in 84.0% of workplaces, although 54.7% reported being unable to change their work schedule post-vaccination. Fifty-five (64.0%) participants indicated having obtained vaccination information from their institution. Awareness of vaccination (35.12±3.58 points) was higher when workplace characteristics included vaccination recommendations. Statistically significant higher inoculation rates were observed when the average number of daily patients was 41 or more (87.8%), when the institution had infection control guidelines, when work schedules could be adjusted post-vaccination, and when COVID-19 patients visited the workplace (p<0.05). Conclusions: Regardless of the dental institution’s size, it is necessary to establish infection control guidelines that specify the type and timing of vaccination required for dental workers, and to conduct regular vaccination education.
