In other cases, however, your C.D.C card—the Weed feelin’s willie good shirt and by the same token and slip of paper that you get after you’re vaccinated— works. For example, Iceland recently reopened its borders to vaccinated U.S. citizens. Upon arrival, you show your passport and that certificate at customs.When you get vaccinated—whether it is at a government-run site or your local Walgreens—a record gets entered into some sort of digitized database. (We aren’t going to get into it, but it might be your healthcare provider’s, a local health department’s, or a state health department’s, depending on where you live. The CDC does not store any immunization records.)Let’s use the Excelsior Pass as an example. First, you enter your basic information (name, birthday, zip code). The technology searches these registries for your record. Once they find you, they ask you a series of identification questions that only you would know, such as your vaccination date, location, and vaccine type. If you answer correctly, you’ll get your code.
