Examining the direct and indirect effects of trust in motivating COVID-19 vaccine uptake.

OBJECTIVES

This study aims to investigate how trust in healthcare providers, public health agencies, politicians, and pharmaceutical companies shaped people's attitudes and behavioral intention associated with COVID-19 vaccination, directly and indirectly via the mediation of vaccine evaluation and emotions.

METHODS

A two-wave longitudinal survey (N = 534) was employed in late 2020 and early 2021 to assess the direct and indirect relationships between trust on people's attitude toward the COVID-19 vaccine, vaccination intention, and actual vaccine uptake.

RESULTS

Results show that trust was positively associated with attitude toward the COVID-19 vaccines and vaccination intention, both directly and indirectly via the mediation of vaccine evaluation, hope, and anger. Vaccination intention also mediated trust's influence on vaccine uptake.

CONCLUSION

Trust in health providers, vaccine manufacturers, and public health agencies are vital to public acceptance of the COVID-19 vaccine.

PRACTICE IMPLICATIONS

Healthcare providers and vaccine manufacturers may serve as the most effective source to communicate COVID-19 vaccine-related information. Trusted health communicators need to highlight the effectiveness and safety of the vaccine while maintaining a positive tone.
