Ya know the medical community does not make this decision easy. I was told the exact opposite by my doctor. You are more at risk if you have had the chicken pox. You bet I am going to ask some questions. Starting with my doctor clarifing this issue. I will also seek out the internet to see what the latest research is showing. I don't like it when patients are getting mixed messages from our medical community about this. I appreciate your response as it is making me take a second look at this issue before I go in. thanks ginnie
