White House health advisor Dr. Anthony Fauci has revealed that the Centers for Disease Control and Prevention (CDC) could soon reconsider its guidelines, recommending vaccinated Americans mask up again.

Top health officials have reportedly been having preliminary talks about revising mask recommendations for vaccinated Americans due to a rise in cases and concerns over the more infectious Delta variant of Covid-19. According to current guidance, those vaccinated against the virus do not need to wear masks in most public spaces.

The revision of the mask guidance is indeed "under active consideration,” Fauci confirmed to CNN on Sunday. The infectious disease expert did not give a timeframe for when the federal guidance could change, but he praised those state officials who had already rushed ahead to reinstate local mask mandates in response to rising coronavirus cases.
