Explaining higher Covid-19 vaccination among some US primary care professionals.

Research in several countries shows higher Covid-19 vaccination willingness and uptake among physicians than nurses. Our paper aims to characterize and explain this difference. In early 2021, we surveyed 1047 U.S. primary care professionals who served adolescents, ages 11–17. The national sample included physicians (71%) as well as nurses and advanced practice providers. The survey assessed the three domains of the Increasing Vaccination Model: thinking and feeling , social processes , and direct behavior change. Covid-19 vaccine uptake was higher among physicians than among nurses and advanced practice providers (91% vs. 76%, p <.05). Overall, in the thinking and feeling domain, higher confidence in Covid-19 vaccination, higher perceived susceptibility to the disease, and stronger anticipated regret were associated with higher vaccine uptake (all p <.05). In the social processes domain, perceiving more positive social norms for Covid-19 vaccination, receiving recommendations to get the vaccine, and wanting to help others were associated with higher vaccine uptake (all p <.05). In the direct behavior change domain, receiving an invitation to get the vaccine and better access to vaccination were associated with higher uptake (both p <.05). Of these variables, most of the thinking and feeling and social processes variables mediated the association of training with vaccine uptake. Physicians had higher Covid-19 vaccine uptake than nurses and advanced practice providers, corresponding with their more supportive vaccine beliefs and social experiences. Efforts to reach the remaining unvaccinated cohort can build on these findings. • Covid-19 vaccine uptake among advanced practice providers and nurses was lower than in physicians. • Vaccine confidence and social norms explained the difference in Covid-19 vaccine uptake. • Recommendations from employers and providers suppressed some differences in vaccination. • Behavioral nudges – invitation and incentives – were associated with more vaccine uptake. • Offers directions and contexts for future vaccination interventions and programs in the U.S. [ABSTRACT FROM AUTHOR]
