Dr. Fauci: Yes, It’s Possible Americans May Have to Carry Certificates of Immunity

CAMEROTA: "Can you imagine a time where Americans carry certificates of immunity?"
FAUCI: "You know, that’s possible. It’s one of those things that we talk about when we want to make sure that we know who the vulnerable people are and not — this is something that’s being discussed. I think it might actually have some merit under certain circumstances."
