Major hospitals are/have been burying the vaccinated status information:

"In the other, larger, major (and I mean major) health system she worked in, if the patient received the vaccine from anywhere but an employed provider’s clinic within the health system (even if the patient had a vaccine card on them), she was forced to put it in an “open field” buried on page 2 of the initial nursing assessment where nobody, and certainly no physician looked for it. All these patients were automatically documented on the main screen as “Unknown”, i.e “Unvaccinated”, even if the dates of each shot were entered into that nursing note field."
