I'm not to sure about your man being a carrier. From what I do know, even if you have had the chicken pox, and your baby is exposed later in life (at like 2 or 3) he/she will more than likely get them. But i'm not sure if they have a vaccine against the chicken pox nowadays.
I do know that it's better to get the chicken pox earlier in life than later. I think they can be fatal if you contract them later on in life....
Hope this kinda helps...I'm not to sure about it though!!
Good .Luck!!
