As inoculations against COVID-19 continue across the country, more governors and state legislatures are taking action to prevent vaccination from being a requirement to access certain goods and services.

The concept, broadly referred to as “vaccine passports,” provides proof of vaccination for activities such as traveling or attending concerts. Americans’ level of support for the idea varies by activity, according to a May 7 Gallup survey. A majority of respondents favor mandated vaccination certification for airplane travel (57%) and attendance at crowded events, such as concerts or sports (55%). But a majority of those surveyed also oppose proving inoculation status to go to one’s workplace, stay at a hotel or dine indoors at a restaurant.

Officials in the Joe Biden administration have repeatedly insisted that there aren’t plans for a federal vaccine passport system. White House press secretary Jen Psaki said during a May 21 press briefing that requiring proof of vaccination is not in the administration’s “intended plan.” Despite that, some governors – mostly Republican – are taking action on vaccine passports.

Here’s where states stand on COVID-19 vaccine passports:

Vaccine passports are banned in this state.

Republican Gov. Kay Ivey on May 24 signed a bill that bans businesses and government entities across the state from requiring coronavirus vaccine passports. Among several provisions, the bill states that “an entity or individual doing business in this state may not refuse to provide any goods or services, or refuse to allow admission, to a customer based on the customer’s immunization status or lack of documentation that the customer has received an immunization.” The law limits the requirements to vaccines approved as of Jan. 1, 2021.

Mike Dunleavy on April 26 issued an administrative order clarifying for the public that the state’s “Executive Branch does not, and will not, require any person to produce their personal vaccine history, also referred to as a ‘vaccine Passport,’ in order to travel to, or around, Alaska.” The order also, however, notes that it will not “infringe on the rights of private businesses” and that the Alaska Marine Highway ferry system is still “allowed to inform passengers on long haul trips of the voluntary choice the passenger can make to provide proof of vaccination and avoid the need for a negative test before boarding.”

Ducey added in a statement, “While we strongly recommend all Arizonans get the COVID-19 vaccine, it’s not mandated in our state – and it never will be.

While there is currently no vaccine passport program in the state, Colorado health department officials said in early April that they were at least exploring the possibility of it, according to The Associated Press.

Jared Polis, a Democrat, said that such a program would be unlikely, CPR News reported. “There is no comprehensive way to have a state vaccination passport,” he said, according to the outlet. “It violates people’s privacy. There’s no practical way to implement it.” Legislation was introduced in the state, however, that would have banned discrimination against clients, patrons or customers based on their COVID-19 vaccination status, according to an April 27 memo from the National Conference of State Legislatures. The bill failed to pass.

I think most businesses are able to do it themselves.”
