What is a COVID-19 vaccine passport, and will I need one? “Vaccine passports," or vaccine certificates, are documents that show you were vaccinated against COVID-19 or recently tested negative for the virus.
They could help you get into places such as stadiums or even countries that are looking to reopen safely. The certificates are still being developed, and how and whether they’ll be used could vary widely around the world.
Experts say they should be free and available on paper, not just on apps, since not everyone has a smartphone. In the U.S., federal officials say there are no plans to make them broadly mandatory.
