I think the discussion of vaccination cards vs paper records over in breaking news is interesting. I don’t want to hijack that thread though.
Maybe we can continue it here?
I think the issue of some people having gotten no card, but only a printout makes things more complicated.
It also means relying on laws against faking federal agency logos won’t work for prosecuting people who get caught.
I also would like to avoid burdening people who did get vaccinated but didn’t get cards.
My preference would be a way to quickly check state registries, and a law against giving false vaccination information, which carries serious penalties based on endangering others.
