不好意思评价你英文是不是很弱
不过以下资讯的说明应该更清楚

The EU COVID-19 Vaccine Passport/Certificate is a one-piece document that can
be issued to a traveller in both a paper and digital format.
Depending on the traveller’s status, there are three types of EU’s COVID-19
passport launched.
Vaccination passport
Test certificate
Recovery certificate
Those holding such a document will be able to travel throughout Europe
without the need to quarantine or test for COVID-19 (though the Member States
may impose such restrictions on particular countries with a higher COVID-19
rate).
所谓疫苗护照证明包含三种，有打过疫苗的可以选第一种，没有疫苗但是有检测报告的选
第二种，因为染疫然后复原具备抗体的可以选第三种
至于你说欧盟有没有限制区域内民众的旅游，现在是有的，但是交由各国家自己管理，例
如，荷兰认为德国是安全国家因此德国游客到荷兰是可以的，但德国尚未认定荷兰是安全
国家所以要进去德国还是要PCR证明。
最后这个护照预计使用一年，如果有需要会再延期，意思应该是如果之后全球疫苗接种都
普及了，疫情也稳定下来，就不需要了。
