"He's dead wrong": Dr. Fauci clashes with Senator Rand Paul about wearing masks after vaccination

Dr. Anthony Fauci told "CBS This Morning" on Friday that Senator Rand Paul is "dead wrong" after the two had a fierce face-off about mask wearing in a Senate hearing. Fauci argues that Americans should continue to wear masks even after they are vaccinated against COVID-19 — something Paul dismissed as "theater."

"Senator Paul has this message that we don't need masks, which goes against just about everything we know about how to prevent spread of the virus," Fauci, the nation's leading infectious disease expert, told "CBS This Morning."  "He was saying if you've been infected, or you've been vaccinated, don't wear a mask — which is completely against all public health tenets," Fauci continued. "So he's dead wrong. I mean, I don't have anything personally against him. But he's just quite frankly incorrect."
