If you can see the lot number well enough to know what it is, (or my husband and I got emails right after the shots, with lot numbers included) - try to write them in and resend. I’ve seen 1 person say SP won’t take the card a 2nd time after they reject it, but also seen one and we were able to too, where they DID accept it a 2nd time). Or if you are lucky like me to be close to your county board of health, try going directly there and explaining the situation. Mine didn’t give a turn around time on the request, but when I went in, they printed it out for me while I was there.I am currently in the same situation with myself and husband. We both got them together. The sticker for the second dose is covering the lot number of the first one and the month of the second dose date. The back of the card has the return appointment date that matches the rest of the displayed date. I am freaking out because the site was a pop up location for vaccine and out department of health stated it can take 10 to 12 days to send to us. I am super stressed. I have shown this card to multiple other places that "required" vaccine cards to be presented and never told anything about lot numbers being fully visible.
