I am newly pregnant and have a 14 month old ds, my mother can't remember if I have had chicken pox 
Would I be being overly health anxious to vaccinate ds against chicken pox to avoid the possibility of him catching it and giving it to me (if I have infact not had it) I wouldn't consider vaccinating ds if I wasn't pregnant, the chance of the vaccine wearing out when he is older and at greater risk of complications from chicken pox worries me.
Ds is starting nursery this month so he will be in contact with lots of other children and germs.
As an aside do you think the midwife or my Dr would do a blood test to see if I have infact had chicken pox?
