KEY POINTS
  • Taking a cruise or heading abroad this year? You might have to be immunized against Covid — and have the "vaccine passport" to prove it.
  • Many travel industry leaders have come out against mandatory vaccine passport usage.
  • The U.S. is not developing a nationwide vaccine passport, so some private concerns are crafting their own, but the European Union and other countries like Israel have developed official standards.

Needing documents to travel is nothing new — after all, checking in for a flight requires some form of ID, and if you're bound for somewhere foreign, it'll have to be a passport. The same goes for car or train trips that cross the U.S. border, where from 2023 you'll need that blue booklet or a state-issued Real ID.

But a passport to simply check into a hotel or board a cruise ship? It's a distinct possibility in this age of pandemic-related restrictions. The idea of so-called vaccine passports proving inoculation against Covid-19 is gaining momentum in some quarters, as consumer interest in travel and tourism picks up along with the pace of vaccination.
