Mixed Support for Vaccine Passport

The CDC’s new guidelines for vaccinated Americans were designed, in part, to encourage the majority of the population to get a vaccine when it became available. As a follow-up to our May 13 post regarding vaccine passports, we asked respondents who refuse to get the COVID-19 vaccine if proof of vaccination becomes a requirement for travel would affect their decision (to continue to decline the vaccine).

Among respondents refusing the vaccine, more than half (56%) said they would not receive the vaccine (“not at all likely”) even if proof of vaccination is a requirement for travel.

However, after more than a year of wearing masks and social distancing, large events such as concerts and sporting events could return this summer and may require proof of vaccination. Our latest results reveal that respondents believe that proof of vaccination should be a requirement for some activities but not others.


Consistent with our previous findings, most respondents believe (“strongly agree” or “agree”), vaccine passports should be required for international travel (69%) and domestic travel (53%). However, there is less support for providing proof of vaccination to enter the workplace and for children to attend daycare or school.
