This study aimed to evaluate the knowledge, attitude, and satisfaction of healthcare workers at Mashhad University of Medical Sciences regarding COVID-19 vaccination.


Vaccination skepticism and refusal to be vaccinated against infectious diseases have been recognized by the World Health Organization to be among the top 10 threats in 2019. Understanding the knowledge, attitude, and satisfaction levels of the healthcare personnel following COVID-19 vaccination can impact societal perceptions of the vaccine and serve as a valuable indicator of public acceptance.


This was a cross-sectional study of an analytical type that was undertaken over three months. A total of 313 eligible healthcare workers were recruited by the census method. A research-made electronic questionnaire was utilized to collect the required data, which were subsequently analyzed using SPSS 22 statistical software. The statistical tests of chi-square, one-sample t, independent t, and one-way analysis of variance (ANOVA) were employed for analysis.


Of the participants, 88 (28.1%) were health staff, whereas 225 (71.9%) were care personnel. The highest frequencies were associated with females (53%) and the age range of 36-40 years (27.2%). The mean knowledge score of health staff was significantly higher than that of care personnel (p = 0.03). In comparison, the mean attitude score of care personnel was significantly larger than that of health workers (p < 0.001). There was no significant difference between health and medical staff in terms of satisfaction (p = 0.36).


Healthcare workers' knowledge, attitude, and satisfaction following vaccination against COVID-19 were above average. Therefore, nationwide notification regarding the levels of knowledge, attitude, and satisfaction with the COVID-19 vaccine is essential to maximize vaccination coverage.
