I was vaccinated via NYULangone (a major healthcare provider in the NYC area); besides receiving a CDC card info about my vaccinations appears in “MYChart”. It seems that MYChart is not just local, several months ago I had a Covid test in LasVegas via a hospital which also uses MYChart—all MYChart entries are linked, so MYChart info may be recognized even outside the USA.
NYS has an Excelscor Card with a QR code, would that also be accepted in EU?
