Does efficacy depend on the number of direct exposures to Covid? I.e., if I got the Pfizer vaccine I have a 5% chance of infection with each exposure? So 100 exposures could result in 5 infections. (I think you explained this in another thread but I've forgotten the answer.)

(Exposure has been defined by the CDC etc. in terms of distance from an infected person and duration of exposure.)

I think you're also saying that my friend's infection is a simple matter of probability, not an indication that the vaccination "didn't take" with her.
