Check out the American Academy of Pedatrics website, www.aap.org
It has the immunization schedule from infancy to adult.
Personally, I think there is a great need for parents to be made more aware of the immunizations they are getting and why they are getting them.
Another great resource would be "The Red Book" It is a book of infectious diseases that you will probably be able to get by speaking with a doctor or ID nurse. If you are still seeing your pediatrician, ask him or her if you would be able to look at it.
I'm not an ID RN, but I worked in a pediatric clinic for four years, and have given hundreds of kids their immunizations.
