We do DTaP because the risk of Pertussis, especially in my family with two babies and one child with respiratory issues, far outweighs the risk of the vax. We delay Hep B until pre-teen age because the risk of them contracting Hep B is very small, IMO. We do Polio because my father had Polio as a child and is now legally blind and has debilitating joint issues. That's not an illness I'm willing to risk my kids getting. We do MMR because I feel that my less healthy children would not handle these illnesses well, although I do have some concern about the safety of the vax. We don't do Rotavirus because of the previous issues with the vax, and the benefit doesn't outweigh the risk IMO. We do pneumococcal because my ped. highly suggested it, though I'll admit I haven't done much reading about it. We opted to do varicella for the older kids who haven't had chickenpox yet because at their age, the risk of them having serious issues from it is much higher. We did end up getting HiB for the three youngest, only because my ped. suggested the Pentacel combo vax and she said she personally has seen much fewer reactions versus the DTaP alone.
I will be giving my older kids the meningicoccal and TDaP booster, but not the Gardasil.
