Re multiple breakthrough infections possible?

Starting a new thread because the other one went off the rails. This is a purely scientific question. I googled it but can't find the answer. Inquiring for my friend who is recovering from a breakthrough infection.

QUESTION: If someone gets a breakthrough infection, does that mean that the vaccination didn't "take" in that person at all, and therefore the person is also susceptible to further infections after the first one?

In other words, if the vaccine fails you once and you get infected, does that mean that (a) you have zero protection from all future exposures, as if you had not been vaccinated, or (b) you still have 95% protection (minus loss of protection over time) for each exposure, i.e., the vaccine failed you once because you had a 5% chance of infection, but it's still active and your chances of infection are unchanged?
