If they are not handing out those cards, they are not in compliance with the protocol.
tldr: Right now, this pandemic doesn’t matter whether someone can prove they got a vaccine or not. What matters is that people do get vaccines.
Just like how all these places are supposed to be checking ID and verifying information before getting the shot? Which most places up and down the West Coast aren’t doing? All you need at many (most?) places is just to state your name and birthdate. Even UCSF has emailed members saying the state and their own system is all based on an honors system and no identification information will be verified. And, I know for a fact that some low-income clinics are not asking for any verification because of the demographics they serve.
Shutting down all these “non-compliant” sites, or not providing them supplies, because they’re not strictly following SOP would be the most ridiculous thing.
As many noted here, we just need more shots in arms as fast as we can.
Also, the lack of vaccine cards still does not negate the fact that one can just easily call their medical provider’s office to tell them you received the vaccine with no proof. Then your medical records can be shown as proof instead of the vaccine card. As someone verifying records, I would be multiples more inclined to believe a personal medical record than a piece of paper that can be easily forged.
