Beliefs and Sociodemographic and Occupational Factors Associated with Vaccine Hesitancy among Health Workers

Introduction: Vaccine hesitancy has been implicated in the low-vaccination coverage in several countries. Knowledge about vaccine hesitancy predictors in health workers is essential because they play a central role in communication about the importance and safety of vaccines. This study aimed to assess beliefs and sociodemographic and occupational factors associated with vaccine hesitancy in health workers. Methods: This was a cross-sectional study among 453 health workers in primary and medium complexity services in a municipality in the state of Bahia, Brazil. The variable vaccine hesitancy was operationalized based on the answers related to incomplete vaccination against hepatitis B, measles, mumps and rubella, and diphtheria and tetanus. Associations between variables were expressed as prevalence ratios (PR) and their respective 95% confidence intervals (CI). Results: Endemic disease combat agents, administrative service workers, and support staff had the highest levels of vaccine hesitancy. Among the analyzed variables, the following were associated with vaccine hesitancy: working in secondary health care services (PR: 1.21; CI: 1.07-1.36), working as an endemic disease combat agent (PR = 1.42; 95% CI: 1.165-1.75), not sharing information about vaccines on social media (PR = 1.16; 95% CI: 1.05-1.28), distrusting information about vaccinations (PR: 0.86; CI: 0.75-0.99), and not feeling safe receiving new vaccines (PR = 1.16; 95% CI: 1.06-1.28). Conclusions: Strategies to enhance confidence in vaccination among health workers should consider differences in occupations and their working settings. Improving vaccination-related content in training and continuing education activities and facilitating access to onsite vaccinations at the workplace are crucial elements to reduce vaccine hesitancy among health workers.
