How do I add a new vaccination to my vaccination certificate? For example, a booster or repeat jab?

In the CoronaCheck app

New vaccinations are not retrieved automatically in the app. Therefore, you have to add every jab yourself. In the menu, choose “Add vaccination or test” and retrieve your vaccination details by logging in with DigiD.

To your paper certificate

Go to www.coronacheck.nl/en/print and create a new vaccination certificate. Your new jab will be added to your paper certificate.
