On Sunday, Fox News host Chris Wallace confronted CDC Director Dr. Rochelle Walensky on the “abrupt shift” she had on mask guidelines in the past week. This came after Walensky announced that vaccinated people can shed their masks in most situations.

“On Wednesday night, you were still arguing, still making the case that people who are fully vaccinated needed to wear masks indoors,” Wallace said. “And then Thursday, less than 24 hours later, you said, no, it changed, now you don’t need masks if you’re fully vaccinated either indoors or outdoors. Would you agree that this abrupt shift was not handled as well as it might have been?”

Wallace went on to add that “things in this pandemic are starting to turn around,” citing the new data the CDC has received in just the past week. He also addressed people’s frustration with previous masking guidelines, as well as the “increasing pressure” the CDC was under.

“Can you state flatly to the American people that pressure had nothing to do with the abrupt shift in the CDC guidelines?” he asked Walensky.

“Yes, I can,” Walensky replied. “I’m delivering the science as the science is delivered to the medical journals. It evolved over this last week. The cases came down over these last two weeks.”

Wallace responded by saying that though the new guidelines are good news for Americans, “it certainly has created some confusion and even concern.”

“Aren’t you in a sense relying on an unrealistic honor system?” Wallace asked, addressing one of the concerns.

“The honor system is to be honest with yourself,” Wallensky responded. “If you are vaccinated, we are saying you are safe, you can take off your mask, and you are not at risk of severe disease or hospitalization from covid-19. If you are not vaccinated, you are not safe. Please go get vaccinated or continue to wear your mask.”

Back in March, Wallensky was warning people of “impending doom” going forward with the coronavirus pandemic, so many have been shocked at just how drastically she’s changed her tune. Check out the interview for yourself below.
