Have you checkd out the vax forum here? I am sure there is more in depth info there. What is interesting, is that I have lots of freinds who also do not vax, and it seems like we all have one thing that we are more concerned about than the others. One friend is worried about measles, one is more concerned about pertussis. Mine is rubella (I still don't vax for it, it is just the disease that concerns me most.) Chicken pox is one of my least concerning ones, because my 3 oldest had it, and it was no big deal.
Anyway, I haven't had any of my kids get pertussis, or any other disease that is vaxed for (excpet chicken pox). Maybe there are more stories in the vax forum.
