There may be electronic submissions to foreign countries (just like electronic visa requests/processing), but the idea of the cutesy "digital passport" that proves your vaccination status that will be accepted at the border is probably not realistic. But who knows, I could be wrong.
The assertion there is no international standard isn't actually true; IATA is developing a standard for vaccine passports based on the existing TIMATIC visa checking infrastructure.
IATA - Travel Pass Initiative They're well positioned to bring together governments and airlines, and I fully expect that if we do end up adopting vaccine passports (not a done deal, but likely) that their platform will be the one that is adopted.
There are other fragmented attempts -
CommonPass — The Commons Project is one - but I think the IATA version is the one that is most likely to succeed based on how deeply the aviation industry relies on their standards.
