The unforgettable COVID-19 shock can only be reversed by a viable vaccination strategy. In this paper, we investigate willingness to be vaccinated (WTV) against the COVID-19. We provide first of its kind empirical evidence on the citizens (N=11,932) of the EU-27 by employing the recent data from the European Commission. Controlling for the correlations in the error terms, we utilize a simulated multivariate probit regression model. Our results show that amongst all the statistically significant drivers of the WTV, the positive perception (vaccination works and has no side effects); R&D information (clarity on how vaccination is developed, tested, authorized) has the largest impact on the WTV. We find that the group of variables on social feedback, and on trustworthy sources of information are to be considered for WTV policy. The counteracting policy gaps are also identified. Our work is novel and has implications for COVID-19 vaccination policies across the EU.
