(WNCN) – A recent poll found that the majority of Americans are in favor of having a COVID-19 vaccine shown in some situations but not so much in others.

According to Gallup results, the majority of US adults favor presenting a mandatory vaccination certificate when traveling by air (57 percent) or at high-profile events such as concerts or sporting events (55 percent).

However, when it comes to staying at your job (45 percent), hotel (44 percent), or restaurant (44 percent), the majority of Americans say that proof of vaccination shouldn’t be required.

These results come from Gallup’s ongoing COVID-19 Probability-Based Web Panel Survey, which will be held from Aug.

With the exception of a handful of states that have invested resources in testing so-called “vaccine passport” systems, most Americans still have few ways to prove that they are fully vaccinated against COVID-19.

A handful of states have banned companies from showing evidence of COVID-19 vaccination. Meanwhile, other states that don’t have such a ban have seen an increase in counterfeiting mimicking the simple 4 by 3 inch cards issued by the federal government.

Many U.S. companies and nonprofits plan to bring their own consumer-friendly options to market. They rely on technical specifications from private sector efforts such as the Vaccine Credential Initiative, which promises “open, interoperable standards”.

Support for proof of vaccination also varies based on your current vaccination status and concerns about the disease.

According to Gallup, no more than eight percent of those who say they won’t be vaccinated are in favor of having proof of vaccination in order to participate in any of the five activities, compared with a majority between 52 percent and 74 percent of those who do or plan to be vaccinated You this.

Meanwhile, 55 to 77 percent of those who are concerned about contracting the coronavirus agree to mandatory vaccinations before participating in all five public activities, but less than half of those who are not concerned about infection.
