I gave my first most vaccines and he developed ezema. I Regretted it. Gave my second none, shes doing great . You can always decide to give them to your son later. Most of the toxic effects have a dose/weight effect so the longer you wait the less damaging they will be. Look at the package inserts and safety studies for each vaccine. Look at the ingredients (particularly aluminum adjuvants). Look at the prevalence of the disease and the fatality rate when it's contracted. It will take a few hours, but the long term health of your son is at stake.
