I went to the doctor last week for immunizations for school. Since I had no records, I wasn't sure if she'd do titers first to check immunity, go ahead and give me shots, etc. Well......I received the MMRV and the Tdap (which was needed because my tetanus was l-o-n-g overdue) and THEN she sends me to the lab for titers for MMRV. But I had just gotten the vaccine 15 minutes before so what would it matter if I was immune or not? In today's mail I received my titer results for the MMRV and I show immunity for everything. Does that mean the vaccines weren't necessary? I'm assuming they wouldn't "kick in" that quickly...or would they? No big deal either way...just curious!
