The Biden administration says it’s leaving digital vaccination records up to states and the private sector.

As Covid-19 vaccine eligibility opens up across the country, the United States is now confronting the question of what to do about vaccine passports. These could be digital certificates or scannable documents that can be used to verify a person’s vaccination status so they can travel more freely or go to large events. Some think a coordinated, nationwide vaccine passport system could help us get back to a semblance of normal life and speed up economic recovery. But this seems unlikely.
