Describe the bug

CovPass shows a 3/3 vaccination certificate as valid for the entry of France, CWA shows it as invalid.

CWA	CovPass

The rule which failed in CWA is: "With Moderna vaccine, a finished vaccination course is considered protective earliest from 28 days after the date of the last vaccination."

Steps to reproduce the issue

1. Add a Booster certificate to your CWA and your CovPass
2. Check the validity for France
3. See that CWA shows invalid, CovPass shows valid

Note: It seems like this only happens for 6 days after the vaccination in the CWA.

Expected behaviour

CWA and CovPass should show the same result.

The CWA is here correct. France has the clear rule independent of 2/2 or 3/3. The vaccination is valid after 7 days. The english translation states 28 days but the rule checks for 7 days like the french description Avec le vaccin BioNTech/Pfizer, un parcours vaccinale terminé est concideré comme protecteur au plus tôt à partir de 7 jours apres la date de la derniere injection. https://distribution.dcc-rules.de/rules/FR/4d1ff7f7a52eb59e4f93752c227a09e2d1e6748fcdb32fa67ad1e9c4686f1147

Im not sure why CovPass is not checking correctly maybe it using the 2/2 instead of 3/3

@thomasaugsten

Thanks for your answer!

I see, I will open the issue in the CovPass repo then.

The user removed the 2/2 cert and still got the same valid message, I will raise the issue in the CovPass repo.

No, this is not the case. The French Government states:

"Le rappel vaccinal est-il obligatoire pour avoir un "pass sanitaire" valide? [...] Toutes les personnes qui font leur rappel disposeront d’un nouveau QR Code, qui deviendra valide 7 jours après leur injection s’il s’agit d’une deuxième dose, ou immédiatement s’il s’agit d’une 3e dose ou plus."

In English: "Is the booster vaccination required to have a valid sanitary pass? [...] All people who receive their booster dose will receive a new QR code which is valid 7 days after their injection if it was their second dose, or immediately if it was their third dose at least."
