COVID-19 Vaccine Hesitancy Among Healthcare Providers.

The predominant reasons for vaccine hesitancy in this cohort of health care workers who had access to, but chose not to be vaccinated (n=500) were a concern for vaccine side effects (69.6%) and the belief that the vaccines are inadequately studied (61.6%). Being a physician, a parent, and having no experience of death in the family or friends had 2.64 times (95% CI: 1.65-4.23, p < 0.001), 1.72 times (95% CI: 1.05-2.81, p = 0.032), and 1.70 times (95% CI: 1.06-2.72, p = 0.028) the odds of strong vaccine refusal, respectively. Older age (35 and up) respondents were 1.83 times (95% CI: 1.24-2.68, p = 0.002) more likely to be open to vaccination.
