Anti-Vax madness

Not being a parent myself maybe I have no place to get involved in this argument but, all the stories about these anti vaccination wackos is really pissing me off. First it was these nutball parents who some how got it in their head that vaccines cause autism. Specifically the MMR (measles, mumps and rubella) vaccine. Their original premise? One, that  heavy metal poisoning (Specifically mercury) cause autism and two, that mercury is used in vaccines.

Well right off the bat they are wrong. There have been no quality studies that show any link between heavy metals, vaccines  and autism, none. But lets say for the sake of argument that they are right and there is some connection. Where does this mercury come from? Well some childhood vaccines contained a preservative called thimerosal which contains mercury (gasp).  Their rationale is that this thimerosal and the increase of the childhood vaccination schedule is the reason why the number of children diagnosed with autism is climbing.

Well even though the original mercury=autism premise is incorrect the FDA caved in 2002 and began to remove thimerosal from vaccines. The result? Autism rates dropped? Nope. Stayed the same? Nope. They continued to climb at the same rate.  Oh and did I forget to mention that the MMR vaccine never contained thimerosal…opps my bad. So what is causing the climbing diagnosis of autism? The most likely culprit is the change of defination of autism not the MMR vaccine.

So with this new information why do the anitvaxers still continue to push their agenda? Well I think it’s mostly due to confusing correlation with causation. The MMR vaccine for example is administered right about the age that kids with autism start to show symptoms. Imagine your the parent of an autistic child and how desperate you would be for an explanation. I feel for these parents, I really do. And I don’t blame them for looking at the vaccines as a possible cause but the evidence is just not there. The truth is that no one knows for sure what causes autism. The evidence so far points to a combination of genetic factors and possible environmental factors in utero but, even that is still very new research.

So if you have kids please get them vaccinated. There are places in the world where kids are dying because of the antivax movement and it’s not in third world countries.

Phil Plait posted this sad story on his Bad Astronomy Blog: Antivax Kills about a 4 week old girl who died from complications from wooping cough. It’s a hard read but, provides a real life example just what the antivax movement can accomplish. As a follow up to this post see this entry where Ms. McCaffery the mother of Dana, the infant who died responded.

EDIT: Just to be clear. The 4 week old girl died not as a fault of her parents but as a result of a immunization rate in that part of the country. My point here being that the vaccination rate dropped to the point where this little girl died because there was no herd immunity to protect her. The data I have is that only 66% of children in that area are vaccinated. Far below the percentage needed to protect the not yet vaccinated. I apologize if my initial statement made it look like it was the parents fault.

    it’s sad about the four week old infant that had to die.

    I just thought of something, in our country, its required to have a proof that your child has been vaccinned before he/she is allowed to enrolled into school. That makes me wonder if the parents would have the doctor sign a waive form for their austistic children? I also wonder if the other countries are required to have the children vacinned before starting school?
