I really don't want to get into a debate about this subject so I'll say no more after this.

Very few Australian vaccines contain thimerosal, and all which do have very small levels. The MMR vaccine has never contained thimerosal as it is a live vaccine and the presence of a preservative like thimerosal would render it inactive. If you are worried about thimerosal it is possible to request from your doctor a list of all vaccines which contain it and about preservative-free alternatives.
