Corona-Warn-App informs users about recalled vaccination certificates

Hanna Heine, on November 15, 2021

To help inform users about misuse and counterfeiting of vaccination certificates, the project team of the Robert Koch Institute, Deutsche Telekom, and SAP have released an enhancement to the Corona-Warn-App version 2.13. The hotfix allows digital vaccination certificates from certain pharmacies to be recalled and marked as invalid in the app.

In the past, there were a few pharmacies that issued fake vaccination certificates. As a result, certificates from the affected pharmacies were recalled. With hotfix 2.13.3 (Android) or 2.13.2 (iOS), the Corona-Warn-App can check the certificates and verify if the certificate was issued by the corresponding pharmacy. If this is the case, the certificate is displayed as invalid.

Important: The certificates are only checked on the users' own smartphones. A recalled certificate will show as invalid when checked with the CovPassCheck app though.

This affects all users who have received a certificate from a pharmacy in question, even if their certificate is valid and genuine. These users can get a new digital certificate at a pharmacy for free. In order to get one, they should bring their yellow vaccination booklet and ID.

The Corona-Warn-App informs users as usual with a push notification. The red dot directs users to the certificate under which they find further information.

The project team recommends all users to update the app to version 2.13.3 (Android) or 2.13.2 (iOS).
