Statement in Children's Health Defense article here.

Rather than recognize the validity of parents’ safety concerns or admit to their own ambivalence about some of the newer vaccines, many pediatricians—nearly two in five according to some estimates—choose to boot uncooperative families out of their practice.

For vaccination, providers receive $400 for each eligible two-year-old who has received all 24-25 vaccines shown below, but only if the provider manages to administer each and every shot to at least 63% of his or her patients. Thus, there is a formidable incentive not to let any patients slip through the cracks.
