Some state governors have issued orders against vaccine passports, but these have only limited meaning, such as not requiring state employees to get vaccinated and not requiring proof of vaccination for state business. The Biden administration has said they’ll facilitate but not require vaccine passports.

That’s the argument that two law professors make, that government action to protect people from public health risks must use the least restrictive means possible. – and vaccine passports are required because they allow people to escape restriction.
