I don’t know what I don’t know...can’t make decisions on what I don’t know...no point in worrying.
Hypothetically, I might know by the doctor’s stated policy.
I sure can’t do much about the herd, so I don’t worry about that, either.
Live and let live, as much as possible.
I have never heard of a doctor who has stated that they do not advice vaccination (but their might be a small quantity out there)...so yes you would most likely never know...so your original statement really is a none starter.
“...so I don’t worry about that, either.”
Being on the other side of this conversation I would agree...I cannot change the full herd so it is not something that I should worry about. My biggest concern of one of my children becoming ill happens when we go to the doctor office...where the majority of the people are vaccinated...and yet still need the doctor's help...
