S.G.
I was torn when it came to the chicken pox vaccine too, especially since I'd heard it doesn't always prevent the child from getting c.p. I ended up getting it for my daughter because the nurse said the c.p. would be much less severe if she did get the vaccine than if she didn't.
I'm still not convinced it was the right decision, but she told me if I waited on it insurance so I went ahead and did it. I want to do a little more research before my son is old enough to get the vaccine.
I guess I'm not much help, but just wanted to let you know I struggled with the decision too!
