Now you have already argued that people who are vaccinated may carry the disease, but what you've not noted is that tranmission is often related to symptoms (coughing, sneezing, etc.). Asymptomatic individuals are less likely to transmit many diseases than those who are are experiencing symptoms of the disease.
Less likely but not impossible, correct? And even those who become symptomatic are contagious before those symptoms present themselves, correct?
your decision to not vaccinate your child certainly does impact people. It impacts immunocompromised individuals, unvaccinated infants, and those who are unreceptive to the vaccine.
You would have to then assume that no vaccination=absolutely contracting the disease. And then after contracting the disease, that person would be out and about rather than homebound or quarantined.
One could argue that an asymptomatic, immunized individual is more of a threat, since they would be unlikely to realize they were infected. As opposed to someone with obvious symptoms of an illness who would be more likely to remain at home and be more aware they are contagious.
You would also have to assume that the only diseases that could compromise these individuals are the ones generally vaccinated for.
Look, I said previously that my children are grown so I'm kind of a disinterested bystander. I'm not afraid of vaccines. I'm just looking forward and I'm not convinced that trying to immunize against every disease imaginable, regardless of their prevalence or mode of transmission is in society's best interest in the long run.
Do we really think we've eradicated polio, for instance? Or did we just cause the virus to mutate into some other virus more virulent than the original? Not too many years ago we had Hepatitis A, B, and C, now we're working our way through the alphabet.
Mostly I am just wary of an attitude that we all must comply and the method of coersion, the spurious arguments used to guilt into acceptance. Let's just say the "government knows best" argument should not get a lot of traction on a conservative site like this. And that, after all, is the crux of this entire thread, since the doctor refuses to treat patients who have not had the required government vaccines. I believe he's free to do as he wishes, but I would personally seek another physician.
