Dr. Anthony Fauci admitted his use of a mask indoors despite being fully vaccinated was for optics purposes.

“I didn’t want to look like I was giving mixed signals. But being a fully vaccinated person, the chances of my getting infected, in an indoor setting, is extremely low,” Fauci said during an appearance on ABC Tuesday. “And that’s the reason why in indoor settings now, I feel comfortable about not wearing a mask, because I’m fully vaccinated.”
