More than 90,000 vaccination certificates suspended due to positive tests over the last 11 days

"A suspension can occur in various cases: when a person has tested positive for COVID-19 in the last 11 days, at the citizen’s request (in the event of loss/theft of the certificate, for example) or for other reasons, because a certificate contains an error or if fraud has been detected. The numbers of suspended COVID certificates are kept in a suspension list. The list displays only the certificate numbers. These numbers say nothing: they are very long and contain no information about the certificate holder. The reason for the suspension is neither visible nor traceable, Digitaal Vlaanderen assures. It is therefore not known whether the 90,000 suspended certificates involve an abnormally high number of errors."

"At the request of virologists, it is planned that the COVID certificate will be temporarily suspended for people who have been vaccinated and who nevertheless test positive. This suspension prevents an infected person who tries to attend events or go to the cinema, café, restaurant or gym from using their CST. Indeed, when it is scanned during a check, it will not turn green. This prevents the person who tested positive from infecting other participants at events. Once the person has recovered – i.e. 11 days after the positive test – the certificate will be reactivated and usable as before."

"Improved data security"

"The CovidScan app, which scans the QR codes of health passes, has been updated in order to restore the confidence of citizens, who were worried about the lack of respect for privacy and about the use
of their data. When the authorities or bar and restaurant owners, among others, scan CSTs, the app checks that users’ Covid certificates are not on the list of suspended certificate numbers."

"In October, a computer science researcher revealed that this list was accessible on the internet. Improvements have been made so that the list remains confidential. As a result, unauthorised persons will no longer be able to find out whether a certificate has been suspended. These changes have already been added to the iOS version and will soon be added for Android, according to the Flemish agency Digitaal Vlaanderen, which develops the app."

"Update 15/11/2021 6 pm"

"Initially, we had not specified in which cases a suspension can occur. As this information is necessary for a proper understanding of the news, we specified during the day that the figure of 90,000 may include errors or fraud."
