Hi!
I am also concerned about the vaccination issue and found a very good book, it's called "The Vaccine Book" by Dr. Robert Sears (Pediatrician). He describes each vaccine, each disease, pros and cons and also gives an alternative vaccination schedule. He has a homepage where also "Vaccine Friendly" doctors are listed. There is one in NYC, here is the link. Haven't tried him, I am still pregnant but maybe it's good to know that there is at least one...
