He responded to this question:
“Even though I’ve had the protection, am I still able to transmit it to other people?”
Of course the 10% would still be able to pass the virus if the vaccine didn't work for them. Naturally.
The Pfizer chief was referring to the ~90%. They just don't know because they haven't had enough time to study the effects. It's a lack of data due to a lack of time.

My point is this: If they are unsure the vaccination will prevent you from getting it , then it must also be uncertain if you can transmit it even having taken the vaccine and not contracting the virus. It’s just a question of probabilities just like everything else in science.
