Abstract

The COVID-19 green certificates were introduced in many countries in 2021 to encourage vaccine uptake against the COVID-19 virus in order to reduce the spread of severe infection among the population, ensure the safety of cross-border movements, and facilitate the resumption of social life and economic activities. 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 and 18 French regions during the summer of 2021. The estimation results show that the green certificate announcement mitigated regional disparities in vaccine uptake. It persuaded undecided people to have their first doses of the COVID-19 vaccine, especially in regions lagging in the mass vaccination campaign. It was less effective in those regions where there was already a high level of vaccine protection. The announcement also proved to be an effective political strategy with which to increase the first-dose rates immediately, but not in the long term.

新冠肺炎绿色证书对法国和意大利地区疫苗接种的影响
2021年,许多国家采用了COVID-19绿色证书,以鼓励接种COVID-19病毒疫苗,减少严重感染在人群中的传播,确保跨境流动的安全,并促进恢复社会生活和经济活动。本研究采用单组中断时间序列方法,研究了绿色证书公告对2021年夏季意大利20个地区和法国18个地区首次接种COVID-19疫苗的影响。估计结果表明,绿色证书公告减轻了疫苗接种的区域差异。它说服犹豫不决的人接种第一剂COVID-19疫苗,特别是在大规模疫苗接种运动滞后的地区。在那些已经有高水平疫苗保护的地区,它的效果较差。这一宣布也被证明是一项有效的政治策略,可以立即提高首次剂量率,但不是长期的。

期刊介绍: The Journal of Policy Modeling is published by Elsevier for the Society for Policy Modeling to provide a forum for analysis and debate concerning international policy issues. The journal addresses questions of critical import to the world community as a whole, and it focuses upon the economic, social, and political interdependencies between national and regional systems. This implies concern with international policies for the promotion of a better life for all human beings and, therefore, concentrates on improved methodological underpinnings for dealing with these problems.
