It's spring 2021. You have just sat through an hour-long interview for your dream job. The vibe is good, and you're pretty sure you crushed it. Yes, you have a work authorization, and of course you're willing to move to the city of X to take the gig. But before you walk out, your future boss asks one last question: "Do you have your COVID-19 immunity certificate?"
You don't, because the antibody test you took months ago turned up negative.
"Oh," she says, "well, I'm very sorry but, in that case, we can't move forward with your application. A shame, but do keep in touch and let us know when you have an immunity certification, ok?"
