Attention: for the upcoming edition of Vivarium, you will need a valid corona entry pass or EU Digital Corona Certificate (DCC).
National authorities are in charge of issuing the certificate. You will receive this when you have a negative test result (make sure you have been tested a maximum of 24 hours in advance and at least 2 hours in advance), proof that you have recovered from corona or when you have a vaccination certificate. Please note that there is a waiting period of two weeks after you have been vaccinated before you can use your vaccination certificate. The national authorities regulate the issuance of the certificate. So check the website of your government for the app or website with which you can generate the DCC.
The certificate contains a QR code which is your corona entry pass. You can also get tested via testenvoortoegang.org.
Are you not from the European Union? You can get your corona entry pass via Testen voor Toegang, even when you are fully vaccinated.
Alongside your valid EU Digital Corona Certificate you will require a valid ID-card or passport. With those two, all that remains is to either buy a ticket at cash register or show your online ticket (buy here).
