CDC reverses guidance on masks for vaccinated people
The Centers for Disease Control and Prevention on Tuesday reversed its mask guidance for vaccinated people due to the delta variant surge.
Vaccinated Americans should now wear masks inside if they’re in places with substantial or high transmission, the CDC said.
CDC Director Rochelle Walensky said data show that on "rare occasions, some vaccinated people with the delta variant … may be contagious and spread the virus to others. This new science is worrisome and unfortunately warrants an update to our recommendations."
Walensky added, "This moment -- and most importantly -- the associated illness, suffering and death, could have been avoided with higher vaccination coverage in this country."
In May, the CDC said vaccinated Americans could stop wearing masks indoors.
The CDC also said Tuesday that masks should be worn in schools by all students, teachers, staff and visitors, even for those who are vaccinated. The CDC said students should return to full-time in-person learning this year with prevention strategies in place.
President Joe Biden in a statement called the CDC's new rules "another step on our journey to defeating this virus."
"While we have seen an increase in vaccinations in recent days, we still need to do better," he added.
