WE chose to vaccinate at a slower schedule.  WE waited until our daughter was 6 months and started with polio.  Then we went in about once a month for ONE more shot!!  WE had all of them seperated (the combo ones can be ordered seperately).  This is the way the International Vaccine Conferences have recommended scheduling the vaccines.  They state this allows the body to deal with them one at a time and not be innundated and overwhelmed thus a lessor degree of possible damage from the vaccines.  The only reason they are not done this way is for fear of lack of compliance.  Anyway, our daughter has done well with them all except the HIB.  She got a high fever from it and we had to stress dose her with advil around the clock.  Julia
