People who believe it's okay not to follow the standard vaccination guidelines say you can follow a popular pediatrician's plan or your own plan. Spreading out vaccines reduces the stimulation of your child's immune system caused by administering multiple antigens and toxins at once. Delaying the vaccines allows the infant's immune system to develop so that she can cope more effectively. And when she has completed the schedule, she still gets all the protection offered by the standard approach.
