The International Air Transport Association (IATA) says governments should not require a vaccine as proof for entry into a country as it could discriminate against people who are medically exempt or refuse to get inoculated.

"In fact, IATA does not support making vaccines a mandatory requirement for international travel," Perry Flint, head of corporate communications USA at IATA, told The Epoch Times in an email. "However, governments set the requirements for border entry and it is up to airlines and air travelers to comply with them."

IATA has developed its own digital passport, called the Travel Pass, which has been tested with over a dozen international carriers.

Flint says the Travel Pass "does not contain a tracking code" and allows travelers to store their vaccination or test results on their smartphone.
