Pfizer chair reveals tiny COVID vaccine detail that could greatly impact the course of the virus

"Clips from the upcoming Dateline prime-time special titled, "Race for a Vaccine" have highlighted Bourla's remarks regarding the Pfizer vaccine's effectiveness in mitigating the spread of the virus. He admitted to host Lester Holt that he was "not certain" if the COVID vaccine would prevent the coronavirus from being transmitted.

"Even though I've had the protection, am I still able to transmit it to other people?"

"I think this is something that needs to be examined. We are not certain about that right now with what we know," Bourla responded."

Makes sense - f you've been vaccinated and catch it, you can still possibly transmit it, not really a surprise, since ~5 out of 100 will still be vulnerable to catching it. Guess it's something they need to get out there, though, but his wording isn't exactly crystal-clear.
