Equal Transmission

 According to the Washington Post writers, this CDC document

“cites a combination of recently obtained, still-unpublished data from outbreak investigations and outside studies showing that vaccinated individuals infected with delta may be able to transmit the virus as easily as those who are unvaccinated.” [emphasis added]

In other words, as far as the transmission of the prevalent delta variant is concerned, it does not matter whether one is vaccinated or not. 

According to CDC analysis both groups appear to become infected and infect others at the same rate.
