> Why should she not trust the doctor that knows our family medical history and has taken care of all of us for, in the case of our children, their entire lives? Because that sounds ridiculous. Unless the allergen that caused your wife's allergic reaction is in the vaccines then there's no additional risk. Consult with an actual immunologist specialist who has a deep understanding of the physical mechanisms behind allergies and can properly weigh the risks from the prior allergic reaction and the risks posed by vaccines. The idea that your GP somehow is better informed than a specialist through having been with you all your lives is very poor logic.
