The Centers for Disease Control has been quietly rolling out a nationwide program called the Immunization Information Systems (IIS), registering your vaccine information into a database.  This effort has been run in parallel with state vaccine registry implementations.
What is the intention of such programs?
My colleague Leslie Manookian, writer and director of the movie The Greater Good, wrote in a recent article, the “CDC has openly stated that vaccine registries are a tool to identify areas of ‘undervaccination’ so that they can be ‘addressed’ and brought into ‘compliance.’” 
I would also add to Leslie’s statement that since the government purchases a large bulk of the vaccines (for example, the Vaccines for Children program), it is in their financial interest to make sure vaccines are consumed regularly.
If you exempt your child from being vaccinated, your refusal is also being tracked and put into the database. If you want to know why this is a big deal, read on. …
“Scientific societies are as yet in their infancy. . . . It is to be expected that advances in physiology and psychology will give governments much more control over individual mentality than they now have even in totalitarian countries. Fitche laid it down that education should aim at destroying free will, so that, after pupils have left school, they shall be incapable, throughout the rest of their lives, of thinking or acting otherwise than as their schoolmasters would have wished. . . . Diet, injections, and injunctions will combine, from a very early age, to produce the sort of character and the sort of beliefs that the authorities consider desirable, and any serious criticism of the powers that be will become psychologically impossible. . . .”—-Bertrand Russell,1953
