Abstract: The COVID-19 green certificates were introduced in many countries in 2021 to encourage vaccine uptake in order to limit severe symptoms and deaths from COVID-19. This study uses a single-group interrupted time series approach to examine the effect of the green certificate announcement on the first doses of the COVID-19 vaccine in 20 Italian regions during the summer of 2021. The estimation results show that the announcement caused a significant immediate increase in the first doses in most of the Italian regions. These results remain robust to a structural breaks analysis for the regions of Friuli-Venezia Giulia and Sicily, which had a share of unvaccinated people below the national average. For these regions, the announcement of the certificate mandate incentivized hesitant individuals to get vaccinated immediately. There were regions, like Lazio, Puglia and Sardinia, which were unaffected by the announcement, most likely because they already had high rates of first-dose COVID-19 vaccination.
