interesting study on babies and aluminium absorption highlights the difference
J Expo Sci Environ Epidemiol. 2010 Nov;20(7):598-601. Epub 2009 Dec 16.Infants' exposure to aluminum from vaccines and breast milk during the first 6 months.Dórea JG, Marques RC.

The success of vaccination programs in reducing and eliminating infectious diseases has contributed to an ever-increasing number of vaccines given at earlier ages (newborns and infants). Exposure to low levels of environmental toxic substances (including metals) at an early age raises plausible concerns over increasingly lower neuro-cognitive rates. Current immunization schedules with vaccines containing aluminum (as adjuvant) are given to infants, but thimerosal (as preservative) is found mostly in vaccines used in non-industrialized countries. Exclusively, breastfed infants (in Brazil) receiving a full recommended schedule of immunizations showed an exceedingly high exposure of Al (225 to 1750 μg per dose) when compared with estimated levels absorbed from breast milk (2.0 μg). This study does not dispute the safety of vaccines but reinforces the need to study long-term effects of early exposure to neuro-toxic substances on the developing brain. Pragmatic vaccine safety needs to embrace conventional toxicology, addressing especial characteristics of unborn fetuses, neonates and infants exposed to low levels of aluminum, and ethylmercury traditionally considered innocuous to the central nervous system.

I really must get some sleep and trying to respond on my iPhone is cumbersome. However, just a thought. I remember reading that the incidence of developing an autoimmune disease after the rubella vaccine was approx 1 in 30,000. However the chance of developing an autoimmune condition after being infected with native rubella in a non immunized individual was 1 in 3000. I can dig the paper up at work tomorrow.

In regards to aluminum - there is about 4mg of aluminum in vaccines and 10mg in breast milk and its even higher in formula. Intramuscular or subcutaneous aluminum will become bound to transferrin (a protein in blood), transported to the kidney and excreted. The removal is approx 50% by 24 hours. It takes approx 3 years for ~97% to be removed. HOWEVER, the aluminum present in our diet also accumulates in our body. By the time we are adults we have around 100mg of accumulated aluminum in our bones, lungs and brains. Only a very small percentage of that has come from vaccines. Regardless of the initial source of aluminum (diet vs vaccines) they will both accumulate. Trying to link the aluminum solely in vaccines to the formation of autoimmune disease is problematic due to discrepancies in the initial source. Remember that aluminum is not present in all vaccines (it's not present in live vaccines like MMR).
