I agree with Jinx, the chicken pox vaccine was the only one that got us. When it was first presented it was a voluntary thing which our Dr. said was not 100% and it was not certain if a booster would be needed in 10 years. When we went back with our son it was mandatory for entrance into the school system. Neither of our children has had chicken pox (bummer, I suppose). I would've rather they had the actual virus and not the vaccine as their antibodies would be more built up.
I did have chicken pox when I was a kid and about 10 years ago I had shingles (same virus which lies dormant in a nerve until something triggers it).
