Overview

This page is in need of updating. Apparently the whole "anti-vax" scare was started by Wakefield's 1998 Lancet paper, which was recently retracted. If there are any other sources or arguments which seem to support vaxophobia, they need to be listed as well. Also, have thimerosal stocks now been depleted? (And finally, filed links below need to be updated...)

There is a popular theory, believed by many parents and a minority of medical professionals and supported by a number of individual cases, that autism may be caused or exacerbated by certain childhood vaccinations – possibly due to the presence of thimerosal, a mercury-based preservative used in the manufacture of vaccines during the 1990s and possibly earlier (it appears that its use began to be phased out in 1999, though it will be at least 2006 before existing thimerosal-bearing stocks are used up or reach their expiration date).

One piece of evidence often brought up in support of this theory is that autism among the Amish (who generally do not use vaccines) is reportedly 1 in 15,000. There are, however, many other factors which could be leading to this low rate. (Is anyone investigating to see what other factors might be at work? Perhaps those factors could help reduce the rate of autism in society at large.)

This theory has been firmly and repeatedly rebutted by the scientific establishment and seems unlikely at this point, but some questions and answers remain to be documented.

Notes

The only remaining anti-vaccine arguments I am aware of are:

  1. People shouldn't be legally forced to accept medications, even if they are truly beneficial, because that puts too much power in political hands. (The determination of benefit may be made scientifically, but politicians often ignore or suppress inconvenient evidence and base their decisions entirely on political considerations.)
  2. It may be that certain genetic traits carry a sensitivity to certain drugs, and that this sensitivity doesn't show up in surveys of the general population due to its rarity -- so surveys might show no correlation, but certain populations would still be affected. Autism is genetically-linked, so it could be that people who are predisposed to autism might also be predisposed to be sensitive to the drug.

Argument #2 is kind of weak and can probably be answered with available data, but I haven't had time to research it.

Argument #1 only applies on a policy level, not as an argument for not vaccinating one's own kids.
