Dr. Anthony Fauci, the director of the National Institute of Allergies and Infectious Diseases (NIAID), has worn a mask outside two days in a row despite being vaccinated against COVID-19 and telling Americans they can lose their masks after getting their shots.

Fauci recently told Americans they could ditch facial coverings after getting vaccinated against COVID-19 and has been vaccinated since January.

However, the NIAID director has been caught rocking a face mask outside the past two days, even though he told vaccinated people himself that they no longer need to wear masks outside.

A picture snapped of Fauci on Sunday shows him posing outside, masked up, with a couple of graduates from George Washington University.

RAND PAUL MOCKS FAUCI OVER ADVOCACY OF MASK USE AFTER VACCINATION

On Monday, another photo of Fauci hit the internet – this time of him meeting with Senate Democratic Whip Dick Durbin, of Illinois, and National Institute of Health (NIH) Director Francis Collins outside.

Again, Fauci wore his mask.

During a Tuesday interview on "Good Morning America," Fauci said he continued to wear a mask indoors up until recently because he didn’t want to "look like [he] was giving mixed signals."

"But being a fully vaccinated person, the chances of my getting infected in an indoor setting is extremely low and that’s the reason why in indoor settings now I feel comfortable about not wearing a mask because I’m fully vaccinated," Fauci said.

Sen. Rand Paul, R-Ky., blasted Fauci for continuing to wear masks after being fully vaccinated during a March Senate hearing.

Paul, an eye doctor by training, has been a prominent critic of Fauci’s guidance that Americans should wear masks even after vaccination while scientists work to understand the effects that emergent COVID-19 variants have on immunity.

"Dr. Fauci, great news! T cell immunity after natural infection shown to include variants," Paul wrote on Twitter. "Do we still need to wear multiple masks after we’ve recovered or been vaccinated?"

NIAID did not immediately respond to Fox News' request for comment.
