Preclinical trials showed the effectiveness of domestic inactivated vaccine candidates for coronavirus disease 2019 (COVID-19). However, it is necessary to evaluate the willingness of the public to receive future domestic vaccines and to understand factors associated with willingness at the early stages of vaccine development.

Through May 25, 2020, 70.48% were willing to receive future domestic COVID-19 vaccines. Confidence in vaccines had the largest impact on public willingness, while age and presence of underlying chronic disease did not significantly increase public willingness.

It is necessary to increase awareness of COVID-19 vaccines among people with high risk of severe infection and to build public confidence in vaccines. Releasing accurate, timely, and reliable data to the public can help increase willingness to get vaccinated.
