Not a published study, but a valid source. I'm posting it here to facilitate searching since I'm sure I will need to find it again (and so might you).

Blue Cross/Blue Shield will give your pediatrician $400 for each child in their practice who is fully up to date on their vaccines by age 2. But the practice has to maintain a 63% fully vaccinated rate (including flu vaccines that have been proven not to work!) or else they won't receive the payout. This is why pediatricians are throwing parents/children out of their practice for not vaccinating. Unvaccinated kids affect the ratio—50/50 and he doesn't get his bonus. So clearly it's not about your child's health at all. It's all about profits.
If the average pediatric practice has 1,000 children, that's a bonus of $400,000! That's on top of what the pediatrician receives for office visits. That's a HUGE incentive to push vaccines at every visit.
And when more and more parents are waking up to the dangers and ineffectiveness of vaccines, this eats away at their "incentives".
