Old post, I know. I just wanted to add that I think a lot depends on the emphasis placed on certain word(s) or parts of the spoken sentence.
Er DU blevet vaccineret!? expresses surprise or disbelief as does,
Er DU vaccineret!? Emphasis on YOU (of all people!). To me there's no real difference otherwise (
er blevet vs.
er)
Er du blevet
VACCINERET?/Er du
VACCINERET? Could also express some level of disbelief, ...or maybe the question is being asked of a person who's hard of hearing (emphasis on the vaccination process.)
ER du blevet vaccineret? /
ER du vaccineret? The 'questioner' focuses on the finite verb... the emphasis is on the vaccination process
being done/completed
And then there's body language, context etc. which may also influence the interpretation of the question.
Er du blevet vaccineret" entails an expectation. Either it already has happened or it is expected to happen.
Even with the emphasis placed on the finite verb, I still don't feel there's any implied expectation (just my personal opinion), e.g.
A: ER du blevet vaccineret/ER du vaccineret? [Have you been vaccinated/Are you vaccinated?]
B: Nej! [No!]
A: Så må du hellere bruge mundbind. [Then you may want to wear a face mask.]
