Does it reflect a state of prior illness where only 1 jab is required instead of 2? Or is the doses element adjusted to reflect that?

Edit: could be in the top level "r" for Recovery group element

Edit 2: no, the recovery element does not allow information on vaccination, and vaccination/recovery group cannot be combined

At least not in Germany, which is a point of contention:

They won't give you a second jab, but they also won't officially recognize you as vaccinated right now. And travel is also problematic since not all countries, not even the EU countries, accept prior illness + vaccine as being fully vaccinated.

These laws look like code that could use property based testing.

The benefit of this system is that at least we have a unified document right now. From what I've heard, covid recovery is indeed part of the QR code so any country accepting half vaccinated people that have recovered doesn't need to deal with different paperwork from every member state.

The lack of getting people a second shot is disappointing, but with the limited availability of vaccines it's understandable from a health perspective. The goal of vaccination isn't to help people travel, it's to prevent a deadly disease, after all.

We'd be better off with a common deciding factor what measures are acceptable to cross the borders, but areas with tourist-centric economies are incentivised to reduce the access requirements, and other countries are paying for those economies while they're still failing, so health and safety wouldn't be the main concern of such a common approach. The national approach doesn't have this problem, at least not for the countries supplying the tourists.

As far as I can tell, the schema does not allow combined information stating "prior illness" and "1 out of 2 jabs". So it does not even provide enough information for countries to decide if that level is acceptable, even if we had a common deciding policy.

My understanding is that vaccination, recovery and a negative test are 3 separate QR codes. You normally only need 1 of the 3.

The J&J/Janssen vaccine requires only one dose as well, and you can get the green certificate after the single dose. Since the format encodes 'doses received' and 'total number of doses' separately, I would guess that people with prior illness can similarly get the total dose number set to 1 there.

It implicitelly does. In that case, the certificate has to show 1/1 instead of 1/2 for a two doses vaccine.

Besides, the recommendation for people who had the infection is to get the shot 6 months after the diagnosis, so it would make no sense to include that information in the recovery one.
