I didn't mean to imply that the decision to vaccinate should hinge, or even be affected, by maternal antibody status. And yes, all parents, regardless of whether they vaccinate, should be familiar with the diseases that typically go around, but realistically, I know I've had to prioritize my learning, and since my doc wanted some of my blood anyway, I asked for titers for a few things and found I didn't have any pertussis antibodies left. So that went a bit higher on the list.
I remember a study someone referenced a while back about reinfection with pertussis, do you have the link? Did it say that most people have antibodies--I have to admit, I skimmed and didn't retain much of that thread.
I have to wonder how it's missed me for who knows how long (or I got it but don't remember/didn't notice and didn't make decent quantities of antibodies), but that can't really be answered.
And Plummeting, Happy New Year!
