Sehr geehrte Damen und Herren,

vielen Dank für Ihre Anfrage zur CovPass-App.

Eine Übersicht über beteiligte Apotheken findet sich im ABDA-Portal unter https://www.mein-apothekenmanager.de/.

1. Die Erkrankung liegt weniger als 3 Monate zurück: Genesenenzertifikat Anspruch auf ein Genesenenzertifikat haben alle Personen, die eine Infektion mit dem Coronavirus SARS-CoV-2 durchgemacht haben und dies mit einem positiven PCR-Test-Ergebnis nachweisen können. Der PCR-Test darf maximal 90 Tage alt sein. Gültig ist das Genesenenzertifikat ab dem 28. Tag nach dem Test und für eine Dauer von 90 Tagen nach dem Test. Das Genesenenzertifikat erhalten Sie in Arztpraxen und Apotheken. Wenn Sie den QR-Code Ihres Genesenenzertifikats in der CovPass-App einscannen, wird Ihnen für die Dauer der Gültigkeit des Zertifikats ein vollständiger Immunschutz angezeigt. Nach Ablauf des Genesenenzertifikats brauchen Sie eine einmalige Genesenenimpfung.

2. Die Erkrankung liegt mehr als 3 Monate zurück: Genesenenimpfung mit Impfzertifikat Ist Ihre Infektion mit dem Coronavirus SARS-CoV-2 schon länger als 90 Tage her, kann Ihnen kein Genesenenzertifikat mehr ausgestellt werden. Dann brauchen Sie eine einmalige Genesenenimpfung. Damit gelten Sie als vollständig immunisiert. Das digitale COVID-Impfzertifikat der EU für die Genesenenimpfung erhalten Sie in Apotheken, Arztpraxen oder Impfzentren.

Scannen Sie den QR-Code des Zertifikats mit der CovPass-App. Hinweis: Auf Ihrem digitalen Impfzertifikat muss bei „Erstimpfung/Wiederimpfung: 1/1“ eingetragen sein. Nur dann kann die App einen vollständigen Impfstatus anzeigen.

Ein Genesenennachweis im Sinne der COVID-19-Schutzmaßnahmen-Ausnahmenverordnung und der Coronavirus-Einreiseverordnung muss aus fachlicher Sicht folgenden Vorgaben entsprechen: a. Die Testung zum Nachweis der vorherigen Infektion muss durch eine Labordiagnostik mittels Nukleinsäurenachweis (PCR, PoC-PCR oder weitere Methoden der Nukleinsäureamplifikationstechnik) erfolgt sein UND b. das Datum der Abnahme des positiven Tests muss mindestens 28 Tage zurückliegen UND c. das Datum der Abnahme des positiven Tests darf höchstens 90 Tage zurückliegen.

Wir hoffen, Ihnen hiermit geholfen zu haben. Für weitere Fragen helfen sicher auch die FAQ auf https://digitaler-impfnachweis-app.de/faq/.

Mit freundlichen Grüßen

das Support-Team der CovPass-App

My Certifikate clearly shows 1/1 and the next shows 2/1. Still I'm not 2G+ according to the app.

[Ein-Tim]

This is because 1/1 is a J&J vaccine and 1/1 J&J is not valid anymore and thus the Biontech vaccination which is 2/1 is only the end of the basic immunisation and not a booster.

The app can't tell whether you were vaccinated after recovery if the recovery certificate is not in the app.

The app would show 2G+ if the 1/1 vaccination would have been with any other vaccine but J&J.

[thomasaugsten]

Please answer to this email and explain that this answer is not sufficient and you need also a recovery certificate after the 180 day because it in this context more than 90 days valid.

[Skeeve]

I already did so and they don't give a f… it seems. In short they tell me that I simply will have try to convince every average Joe who does not understand that I'm 2G+. :(

[Ein-Tim]

I think CWA can't do anything here... 😕

[MikeMcC399]

@Skeeve

Are you interested in your 2G+ status for a particular federal state? If yes, please let us know which one that is.

The legal regulations are a combination of federal ones across all Germany and local federal state regulations. I find it very complicated. To add to that, it is continually changing as well!

[Skeeve]

@MikeMcC399 It's NRW and the rules seem to be clear: My status is 2G+ but the app can't show it because my first vaccination was with J&J and I have no scanable certificate proving that I had Covid 19 a year ago.

[MikeMcC399]

@Skeeve Thanks for the clarification that you are interested in NRW. That is helpful to be able to refer to the right regulations. If the regulations only allow for certificates of recovery to be issued for a freshly recovered person, and the app needs a recovery certificate to do the check, then the app doesn't have the information available, since you are no longer freshly recovered. This is a gap between what the regulations define for 2G+ and what they allow in terms of IT certificates.

I don't know whether the law-makers will close this gap. It doesn't seem like there is anything planned in the short-term and the new regulations starting today, March 19, 2022 have not changed anything in this respect. Some situations which previously required 2G+ now only require 3G, so that may help you.

To prove 2G+ regarding recovery you will probably have to do this with paper-based evidence.

Based on what you know, do you think that there is anything more that the app could do to help you?

[Skeeve]

Based on what you know, do you think that there is anything more that the app could do to help you?

I honestly doubt it.

[Ein-Tim]

Hey @Skeeve, did the situation improve with the last updates? Probably not, right?

[MikeMcC399]

• This issue is probably now obsolete, since there is no longer 2G+ defined and in use for NRW. See https://www.land.nrw/pressemitteilung/gesundheitsministerium-erlaesst-neue-coronaschutzverordnung from April 2022.

• Secondly, according to https://github.com/corona-warn-app/cwa-app-ccl/issues/44 the last vaccination of @Skeeve was in November 2021, so possibly it would be time for a booster vaccination to have been done. If a booster has been done and the certificate scanned in, then the app may now be showing a 2G+ status by now.

@Ein-Tim It did not improve @MikeMcC399 You ar right about the Booster and I received it Tuesday. BUT… The App couldn't scan the certificate. I think this was due to an error they made when entering my data. They entered "23.6." as the date at one point but "23.8." at another point. I deleted the certificate and still have to go to the next pharmacy to get a fixed one.

[Skeeve]

I got my certificate for my last Booster yesterday and now it's 2G+.

Issue simply was that I had no certificate for my infection and couldn't get one because it was too long ago.

@thomasaugsten / @mlenkeit

I have a Twitter user with the following immune history:

• Recovered
• Vaccinated (1/1)
• Vaccinated (2/1)

As it is not possible to get a recovery certificate for the recovery CWA shows that the user is not fully vaccinated according to the new IFSG. Is there any way the user could work around this problem & which advise is the CWA-Team issuing to users with this problem in general?

[MikeMcC399]

@Ein-Tim

Did you check the legal text? IfSG § 22a asks for a positive test before 2 vaccinations, not a recovery certificate.

"Abweichend von Satz 2 Nummer 2 liegt ein vollständiger Impfschutz bis zum 30. September 2022 auch bei zwei Einzelimpfungen vor und ab dem 1. Oktober 2022 bei zwei Einzelimpfungen nur vor, wenn 1. die betroffene Person einen bei ihr durchgeführten spezifischen positiven Antikörpertest in deutscher, englischer, französischer, italienischer oder spanischer Sprache in verkörperter oder digitaler Form nachweisen kann und dieser Antikörpertest zu einer Zeit erfolgt ist, zu der die betroffene Person noch keine Einzelimpfung gegen das Coronavirus SARS-CoV-2 erhalten hatte,"

[Ein-Tim]

@MikeMcC399

That's good news, because the user can proof their status by showing the documentation on the positive test which they got from the lab.

However, it dos not answer the question if this problem is known and what the user can do so that CWA shows the correct status.

[MikeMcC399]

@Ein-Tim

I don't know the answer and it seems more a general question.

An Antigentest is not the same as an Antikörpertest. See for instance https://www1.wdr.de/nachrichten/themen/coronavirus/corona-test-unterschied-schnelltest-pcr-antikoerper-100.html

So far there has been no mention of an Antikörper test certificate in any form in relation to CWA.

Probably this would be better as an open general issue if the app is able to support this aspect of the IfSG regulations in any form.

[MikeMcC399]

@Ein-Tim

The current rules are well explained on the official site https://www.infektionsschutz.de/uk/coronavirus/fragen-und-antworten/regelungen-fuer-geimpfte-und-genesene/#tab-5344-0. They don't however go into detail about using the apps.

[Ein-Tim]

Probably this would be better as an open general issue if the app is able to support this aspect of the IfSG regulations in any form.

Would you like to do this or should I do it?

[MikeMcC399]

@Ein-Tim

Would you like to do this or should I do it?

You are welcome to go ahead, as I have no personal experience with "Antikörper" tests.

[Ein-Tim]

@MikeMcC399

Me neither but I'll try to figure it out (:

[thomasaugsten]

@Ein-Tim We reported the issue regarding the 180 days issuing limit of recovery certificates. We need a few days for an official solution for this issue

[Ein-Tim]

@thomasaugsten Thanks for the update! I opened https://github.com/corona-warn-app/cwa-documentation/issues/920, so we can communicate in that issue from now on.

[thomasaugsten]

Please consider to create a covpass ticket to ensure all participating apps are aware of this issue
