A debate has ensued over ‘vaccine passports.’ This illustration photo taken in Los Angeles on April 6 shows a person looking at the app for the New York State Excelsior Pass, which provides secure, digital proof of a COVID-19 vaccination, in front of a screen showing the New York skyline. As the United States' vaccination campaign accelerates, so-called vaccine passports are gaining traction despite political divisions and privacy and freedom concerns.

According to critics, such provisions amount to forced vaccinations that will violate privacy and civil liberties and undermine trust in public-health authorities.
