Sue, I transplanted at Mayo MN, but did not get my vaccine at Mayo. I wonder if that explains why I got a card and you didn’t. Anyway, I did contact my transplant coordinator, sent her a copy of my card via my private patient portal, and she has it posted in my Medical Records -Immunization Record.
Have you checked your Patient Portal under Immunizations? If that doesn’t work for you, then I would most definitely contact Mayo.

Hi @sue6175, The Vaccination card was created by the CDC to be a helpful reminder and a way to confirm that the correct second dose is provided to you. At Mayo Clinic, however, the card is not necessary because Mayo is able to track when you should return and which vaccine you will need for your second dose. Should you have a need for the information on the card, it will be made available in your Patient Online Services account under immunizations.
