Here is exactly what CDC Director Dr. Rochelle "everyone calls me Rachel" Walensky said on AUGUST 6th about Delta:
(CNN)Fully vaccinated people who get a Covid-19 breakthrough infection can transmit the virus, 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's why the CDC changed its guidance last week and is now recommending even vaccinated people wear masks indoors again, Walensky said.
Last week, the agency released a study that showed the Delta variant produced similar amounts of virus in vaccinated and unvaccinated people if they got infected -- data that suggests vaccinated people who get a breakthrough infection could have a similar tendency to spread the virus as the unvaccinated.

Please note there is TRANSMISSION, which occurs through direct or indirect contact, droplet or aerosol, and INFECTION, which occurs within the transmissee. The vaccines DO NOT prevent transmission, per CDC and many other qualified scientists and doctors. Some say they prevent infection, and limit severity of infection, and our blue member here appears to be saying that by his read of recent NY state data the rate of infection of vaccinated individuals is lower.
I'm not sure that interpretation factors in that reported rates are MUCH lower than actual rates of transmission and infection, and that what may be occurring is vaccinated are more likely to be symptomless and therefore less apparent.
Further, Omicron, which is clearly much more transmissible than Delta, in some studies, is MORE likely to infect the vaccinated than the unvaccinated, so we have no clarity yet from scientists.
As Miss AP said, the regrettable politicization of all this makes it even harder.
