Most pedi's don't use the mercury shots anymore where they don't have to. There has been a ton of (European based) research that shows mercury doesn't cause autism. Pollution and genetics probably play a bigger role in autism. It is probably much more concidental that the shots are given at a development time where autism is much more commonly diagnosed. Of course, take that with a grain of salt. Mercury isn't good for you anyhow.
Thanks for the informative post.
One thing I have to add is that mercury compounds (the group that thimerosal is part of) have been used for a long time as preservatives. That's why it was in the vaccines and the amount of thimerosal in each dose was very tiny. Some vaccines (like MMR) were preservative free to start with.
One interesting thing to think about when thinking about relative risk, is that most people over the age of 35 were exposed to
a lot of mercury, not just the small amounts used as preservatives in vaccines. One of the products we used when I was little (I'll admit to being over 35) was called Mercurochrome (another mercury compound - this one used as a disinfectant, not a preservative). And, not just a trace of mercury, Mercurochrome was up to 26% mercury.
We actually likes getting cuts and scrapes because that meant we got to use the Mercurochrome. It came in a bottle with a sort of dropper on it that you were supposed to use to drop the mercurochrome on the cut (nothing like putting mercury right into your bloodstream).
That's not what we did though.....
Of, course, we put it on the cut or scrape, but.......
it was a cool, orange color and we used it to paint designs on our arms or legs - at least until our moms stopped us. And, they knew to stop us because.........
they did the same thing when they were kids.
I didn't actually know any kids who
didn't use mercurochrome. And our moms and dads had used it too. And their moms and dads.....and, (depending on how old they were), their moms and dads too. It started to be used in 1919.
Here's an
interesting link about what happened to Mercurochrome. And an encyclopedia entry
about Mercurochrome.
So, if you concerned about the small amount of thimerosal that used to be in vaccines, think about the mercurochrome your parents used to paint themselves with. If you ask them, I'm sure you will make them smile.
