The World Health Organization does not support vaccine passports to be used for travel, according to Fox News.

Margaret Harris, WHO spokeswoman, said the world health agency does not back the use of these passports because it is not yet known if those who have been vaccinated against the virus can still transmit it.

“We as WHO are saying at this stage we would not like to see the vaccination passport as a requirement for entry or exit because we are not certain at this stage that the vaccine prevents transmission,” Harris said.

“There are all those other questions, apart from the question of discrimination against the people who are not able to have the vaccine for one reason or another,” she added.

Dr. Anthony Fauci said, “I doubt that the federal government will be the main mover of a vaccine passport concept.”

“They may be involved in making sure things are done fairly and equitably, but I doubt if the federal government is going to be the leading element of that.”

“I’m not saying that they should or that they would, but I’m saying you could foresee how an independent entity might say, ‘well, we can’t be dealing with you unless we know you’re vaccinated,’ but it’s not going to be mandated from the federal government,” he said.

Some argue that mandating vaccine passports could speed the re-opening of international travel. But the issue of vaccine passports is complicated and has been hotly debated around the world, with questions largely around how much governments, employers and venues have a right to know about a person’s vaccination status.

In the U.S., the issue has largely become partisan, with Republican lawmakers mostly against the concept. Florida Gov. Ron DeSantis, for instance, issued an executive order on Friday banning the use of vaccine passports in the state, while Democratic New York became the first state to roll out a digital vaccine passport when it recently launched the so-called “Excelsior Pass.”

Still, some private businesses and organizations may look at developing ways to confirm that someone is vaccinated. Fauci also spoke to this during his appearance on the Politico Dispatch podcast, noting that businesses or schools may require them to enter their buildings.
