well.... there you have it:
Covid-19 vaccines no longer prevent transmission, CDC director says
Covid-19 vaccines no longer prevent transmission, US Centers for Disease Control and Prevention Director Dr. Rochelle Walensky said Thursday.
“Our vaccines are working exceptionally well,” Walensky told CNN’s Wolf Blitzer. “They continue to work well for Delta, with regard to severe illness and death – they prevent it. But what they can't do anymore is prevent transmission.”
That is why the CDC is recommending even vaccinated people wear masks indoors again, Walensky said.
“If you're going home to somebody who has not been vaccinated, to somebody who can't get vaccinated, somebody who might be immunosuppressed or a little bit frail, somebody who has comorbidities that put them at high risk, I would suggest you wear a mask in public indoor settings.”
