Jerry and wife,
My personal opinion is to get a pediatrician that is will reviewed, that you like, works for a well known and established practice in your area, and get all the immunizations recommended by them.
If you spend time on-line, here, at this site, other sites, med-sites, and even more dangerously on various "board" and "forum" sites, then you tend to hear a lot of horror stories which are the extreme outlying cases. It's like coming to this site and lurking...one would think that STs and Fords have chronic problems - not really true, that's just mostly what gets talked about. The same is true on med-related forums. You would think that every kid out there is getting autism from immunizations given what you read on certain sites...and that's just not the case.
I do personally recommend MMR and chickenpox shots for whenever the physicians recommend.
Actually, and this is important, I think that "because everyone else is", is one of the biggest reasons to immunize your children. You seem to dismiss that as a reason. I wouldn't be so quick to do that. Said slightly differently, many of these immunizations are MOST effective when the majority of the population is immunized. Therefore, it could be viewed as a little "selfish" to not get one's child immunized because one feels that the risk of an exposure and a related issue is not that bad when compared to the risk of a reaction from the immunization (essentially that's what it comes down to, right... comparing the risk of one vs. the other?) If everyone felt that way fewer and fewer would get immunized and the risk of exposure would skyrocket...for everyone.
So, I say: Do your part as a parent, for your child, for the rest of us and for the rest of the children, and get all the recommended immunizations.
You asked...you got my opinion. Ultimately you will do what you feel is right for your child.
