--the USA Today reported in a passage that was later scrubbed from an article.
A screenshot from the article and an online archive of the passage points out the surfacing evidence.
The story from the USA Today drops the reference to NBC News, but nonetheless corroborates the news: "CDC says vaccinated people may transmit virus, recommends masks indoors."
"CDC Director Dr. Rochelle Walensky said new data shows the delta variant, which accounts for more than 80% of the new infections in the U.S., behaves 'uniquely differently' from its predecessors and could make vaccinated people infectious," the article notes.
"Information on the delta variant from several states and other countries indicates that in rare occasions some vaccinated people infected with the delta variant after vaccination may be contagious and spread the virus to others," Walensky said in announcing new guidance, which reverses a CDC recommendation in May. "This new science is worrisome and unfortunately warrants an update to our recommendation."
