The idea of “vaccine passports” is starting to become a divisive issue, but the reality is many businesses likely will begin to require patrons to show some kind of proof of vaccination against COVID-19. The good news is businesses and governments have options for how they might want to implement this requirement. On this bonus episode of Public Health Review, Kevin Richardson, Outside Counsel on Global Government Affairs for Zebra Technologies Corporation, discusses how a business or government can create vaccine credentials that are more sophisticated than CDC’s paper cards, but also protect a holder’s personal information. Richardson explains digital vaccine credential options, outlines their security features, and considers the policy outcomes for entities looking to confirm that people are protected against COVID-19.
