Unfortunatly, while dr.s should be looking for "vax preventable diseases", most assume children are fully vaxed, and most of these "vax preventable diseases" are so few and far between, except for the occasional outbreak, that dr's rarely check first for them. I am opposite of most posts here, I specifically make it a point to tell them my DS is unvaxed. Usually, I'm just calling the 24 hour nurse about a symptom/s/ I am concerned about, but I always am adamant about him not being vaxed just in case. I want them to make it a point, so they will think to include these diseases in their "diagnosis" if that is ever the case. I am lucky to be in a state with philosophical exemptions, and I don't care what these md's opinions of are me, and some (more so their nurses) have made their opinions known, but I stand firm, as this is my decision, my educated and over researched decision, and it is important to me, when someone else is diagnosing my son, that they have complete knowledge. Now, if he went to ER for a broken arm, I wouldn't be standing there with my finger in their face saying "He's not vaxed" in that nasaly voice, but with respitory/fever/other symptoms, you better believe I'm telling them!!
