Chickenpox Vaccine or Not?

At my daughters next Dr. appointment I heard that they will want to give her this vaccine. What did you do? I'm leaning more on the side of just letting her get chicken pox when she gets it, I worry about giving her a vaccination that is relatively new. I mean we’ve all had the chicken pox, I’d rather let her get that on her own than potentially harm her with a vaccine. What are your opinions?
