That’s what ordinary third-party sigs do. Adding medical data to a
public key does not add anything to the process.

If it would be only medical data you are correct! But, and here a big but, holder *digitally signed* by EU *authorities* in this field while the cert

You should also beware that medical information is treated as
sensitive personal data under GDPR, and this subject to stricter
rules. Keyserver operators already have enough legal issues handling
ordinary personal data (email addresses etc) without adding
vaccination certificates to the dataset.

As I said a duplicate key is not meant for keyserver distribution and
if this should happen by accident, well than it happened. No one can
be sued about this. It is or was only said in some news that one should
not publish such QR-codes on social media.

At its core, the problem here is you still are not proving this verifiable secret has not been shared with any other party. Are these being scanned to go to work? Are these being scanned to travel? Are these being used in other hypothetical key exchanges? I am going to assume you currently have one of these QR codes. Assuming you want me to sign your public key, prove to me now that you have never shared or shown it to anyone ever. If you cannot do this, I cannot be assured you are the actual party that is sharing it as it could have been an earlier party you shared it with or someone eavesdropping on the communication channel you shared it upon.
