LOS ANGELES - While proof of a negative COVID-19 test is required for anyone traveling to the United States, so-called "vaccine passports" could be the latest development for some European countries in curbing the spread of the virus globally.
Currently, the U.S. Centers for Disease Control and Prevention requires anyone flying to the U.S. to show proof of a negative coronavirus test.
On Feb. 8., Transportation Secretary Pete Buttigieg hinted that the CDC was considering whether to impose requiring negative COVID-19 tests for domestic airline flights as well.
