COVID-19 Vaccine Hesitancy Among Healthcare Personnel Who Generally Accept Vaccines

To identify psychological antecedents of COVID-19 vaccine hesitancy among healthcare personnel (HCP). We surveyed 4603 HCP to assess psychological antecedents of their vaccination decisions (the ‘5 Cs’) for vaccines in general and for COVID-19 vaccines. Most HCP accept vaccines, but many expressed hesitancy about COVID-19 vaccines for the psychological antecedents of vaccination: confidence (vaccines are effective), complacency (vaccines are unnecessary), constraints (difficult to access), calculation (risks/benefits), collective responsibility (need for vaccination when others vaccinate). HCP who were hesitant only about COVID-19 vaccines differed from HCP who were consistently hesitant: those with lower confidence were more likely to be younger and women, higher constraints were more likely to have clinical positions, higher complacency were more likely to have recently cared for COVID-19 patients, and lesser collective responsibility were more likely to be non-white. These results can inform interventions to encourage uptake of COVID-19 vaccines in HCP.
