SOMETIME SOON, YOU might arrive at an airport or a stadium or a restaurant, open an app or flash a card, and be admitted to a place or experience that was denied you during the pandemic. You will have just deployed a vaccine passport, a certification of either vaccination status or immunity following a natural infection that confirms you no longer pose a risk to others.
“Soon” is right now in Israel, where a passport debuted in February that lets vaccinated people attend events and patronize restaurants and gyms in the country, and in Estonia and Iceland, where proof of vaccination allows non-citizens to enter without quarantine.
