Does the state have the right to make medical decisions? Interesting question, regardless of your opinion on childhood vaccines, their efficacy and their safety:
"Mandates have a profound effect on medical practice. Once a vaccine is mandated for children, the manufacturer and the physician administering the vaccine are substantially relieved of liability for adverse effects.(3) The relationship of patient and physician is shattered: in administering the vaccine, the physician is serving as the agent of the state. To the extent that the physician simply complies, without making an independent evaluation of the appropriateness of the vaccine for each patient, he is abdicating his responsibility under the Oath of Hippocrates to "prescribe regimen for the good of my patients according to my ability and my judgment and never do harm to anyone." Instead, he is applying the new population-based ethic in which the interests of the individual patient may be sacrificed to the "needs of society."
If a physician advises against a mandated vaccine, he faces increased legal liability if the patient is infected with the disease. In addition, he may risk his very livelihood if he is dependent upon income from "health plans" that use vaccine compliance as a measure of "quality.""
The above is just a short excerpt from a lengthy article, and the website has several interesting little nooks. Enjoy!
