The full onsite continuation of the Eurekaweek can only be possible by using the CoronaCheck app. This app gives you a corona admission ticket when you have tested negative, got proof of recovery or are fully vaccinated. For most events taking place during the Eurekaweek, a corona admission ticket in the CoronaCheck app is required.
It is important to note that when coming from abroad, a proof of recovery or full vaccination can only be entered in the CoronaCheck app when you can present a Digital Corona Certificate (DCC).
You can test yourself on the corona virus before and during the week using the foundation Testen voor Toegang. A negative test needs to be no older than 24 hours, so you need to test a couple of times during the week. Testen voor Toegang has several sites in Rotterdam where you can do a corona test.
