I posted some of this on another forum, but I thought I'd re-post it here. This is in response to you, kate123A.
I believe it is important for people to look at BOTH sides of any debate with an open mind. I find that for many, especially parents of autistic children, the vaccination issue becomes such and emotional one that there is an inability to look at the facts objectively.
As a new mother, I can say that I can relate to the emotions involved - especially when it comes to wanting to keep your children safe. But we must remember that there are now parents out there mourning the loss of children to vaccine preventable illnesses (including infants who were too young to have been vaccinated) because of recent decreases in vaccination rates.
Saying that not vaccinating yourself or your children is a personal choice that does not impact others is simply false, and I think it is about time people accept this as a fact.
The statistics regarding autism rates increasing proves that the number of diagnosed cases of autism is increasing (I say diagnosed cases because diagnosis is, in and of itself, subjective). Why are autism rates increasing? We don't know yet. But scientists are certainly looking for reasons. To-date, vaccinations have not been shown to cause an increase in autism rates.
The statistics regarding the decline (and in some instances, elimiation) of diseases proves that vaccinations have been, and still are, effective. Recent outbreaks underline this, as it has shown what can happen when herd immunity is lost. This is a known scientific fact. Yes, there are potential risks associated with vaccination, but there are potential risks with any medication (have you ever read any of those inserts included with medication? any medication?). Also, there is a subset of the population who genuinely cannot tolerate vaccinations (due to underlying medical conditions, allergies, etc.), and herd immunity is what these people rely on to stay out of the path of vaccine-preventable diseases.
As for vaccinations overly stressing the immune system, I believe this argument is rubbish. When your immune system is busy fighting invaders you get a fever. How long, and how severe, are fevers associated with getting the flu? Measles? Diptheria? etc. Now, compare that to the severity and duration of fevers one might have after getting a vaccine.
One of the paradoxes of vaccines is that, the more effective they are, the less necessary they appear to be.
Vaccines have been so effective that many severe and debilitating illnesses are no longer a part of our cultural memory. If you doubt this, ask anyone who was born before the 1940's... aren't many of them left, are there? Or ask those who may have immigrated from less developed countries.
I for one hope we don't return to the days when families expected to loose one or more children to illness simply because the anti-vaccination movement gains enough traction with no conclusive studies to back it up.
