Thanks for the info. I will try to recover the information and a new card.
Info on what to do with the card - like not laminating it and definitely taking a photo of it but not posting that photo on social media - and also what to do if you lose it -

I got my vaccine back when the only place to get them where I live was at community centers by appointment in mass vax campaign, and we were all told to take a photo of it with our phones before we left. I did, but of course, phones don't last forever and stuff gets lost, so I've had the same concern. Some have offered lamination services so it will last longer, but then, that prevents it from being updated when we will all need to get our booster shots possibly for the rest of our lives but certainly soon as a recent study from Israel shows the Pfizer vax is already losing some immunity from the first folks who got vaccinated. I was told it would not be easy to get a replacement, which is why they told everyone to take a photo of it. By the time my wife got vaccinated, she was able to get it at our doctor's office, and was not told to make a photo of it, so there you go. I told her to do that. I hope replacements are easy to get, but I'm dubious. From what I understand from the newspapers and comments from former gov't public health folks, the prior administration was so pro covid that they didn't really set up good data, and so the new administration doesn't have good access to that data. It probably exists somewhere, but if your priority is not on beating covid, then the focus is on other things, which it was. I hope you'll come back and tell us the card was easily replaced. As for the need to show the card, it appears that won't happen everywhere but it might somewhere. The US will never have a vaccination requirement given the political situation, but some employers will and some won't (some Republican led states have banned such requirements, but whether that is legal or not is in question for private parties), and in some other countries you'll have to show proof of vaccination and in others you won't, which means the importance of having that card is in question as the populist roadblocks to vaccination and ending covid in the US also exist in many other countries. So again, let us know if Annie is right and it turns out to be easy to get a replacement card.
When I got one, they told me, "if you lose it, contact us and we'll have another one sent to you." The records aren't just kept by the hospital or drugstore, it's reported to an online vaccination registry. Not hard to get a replacement.
That said, the first thing I did when I got my vaccination card (while still at the pharmacy where I got the shot) was photograph it with my phone. The second thing was Xerox it when I got home. Same when I got my second shot.
I don't think your family member is in trouble. The cards are replaceable.
