For that matter ~ you can be sued even if the patient followed your advice and was a "good little patient" and did everything you requested. I think it is a lame excuse on the part of physicians to presume they know all. I think a collaborative effort on the part of both the physician and the patient is a good mix ~ not a "doctor knows it all" kind of attitude.
Disclaimer ~ I am not trying to be snarky or respond to your own individual experience...however I have been fired from a ped for refusing vaccines for my children. I was fired without any back up information or discussion as to why I am not vaxing ~ just a blanket statement of "if you do not vax, we will not see your children".
