The World Health Organization said it doesn’t back the practice of requiring so-called vaccine passports — noting that it’s still unknown whether the shots prevent transmission of COVID-19.

“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,” WHO spokeswoman Margaret Harris said at a briefing Tuesday.

“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.”

Some countries, such as the United Kingdom, are considering requiring some form of proof of vaccination to allow people to attend events or board flights.

The US federal government, however, has indicated that it has no plans to require similar verification.

Andy Slavitt, a senior adviser to the White House COVID-19 response team, has said President Biden’s administration will provide guidance to the private sector on how to develop the passports.

“The government is not viewing its role as the place to create a passport nor a place to hold the data of citizens. We view this as something that the private sector is doing, and we’ll do what’s important to us,” he said at a press briefing.

Dr. Anthony Fauci also said Monday that the federal government “may be involved in making sure things are done fairly and equitably.”

“But I doubt if the federal government is gonna be the leading element of that,” the president’s chief medical adviser told the “Politico Dispatch” podcast.
